SCV400RD-050 Slow Cooker

The Crock-Pot is what one would call a good slow cooker. The temperature control is good and the handles hardly heat up, even if the case gets a little hot. This means that the heating is average. However, our recipe is the best in this cooker and we can definitely recommend it for use.

The VonShef - Slow Cooker Slow Cooker has all desirable features and is easy to use. Unfortunately, the handles and the case become a bit hot for several hours and the recipe is not quite as successful in this slow cooker as in other devices.

Klarstein

35 Slow Cooker

Unfortunately, the Klarstein - 35 Slow Cooker does not have a warm-keeping function. You can set the temperature control to automatic, but then the cooker itself decides when the food should be kept warm. It would be better if this could be set manually. In addition, the appliance smells a lot like plastic. However, the Slow Cooker did best in temperature control. Thus it is still rated well in our test.

Russell Hobbs

24180-56 Slow Cooker

The Russell Hobbs - 24180-56 Schongarer was unfortunately very hot during the test process. It has partially cooked our food to over 100 °C, which is not the purpose of a slow cooker. Fortunately, from the outside, the cooker has not warmed up as much as the rival devices and it is also positive that you can write on the surface with chalk. Nevertheless, it can not compete with comparable devices in terms of performance.

Our winner

The Crock-Pot is what one would call a good slow cooker. The temperature control is good and the handles hardly heat up, even if the case gets a little hot. This means that the heating is average. However, our recipe is the best in this cooker and we can definitely recommend it for use.

  • Do not use the Slow cooker to heat cold food - it is not suitable for this. Keeping warm, however, works very well.
  • Avoid lifting the lid often. So the pot loses heat and moisture - the cooking process takes longer and possibly the food burns.
  • The best way to cook food is when the container is at least half full. But he should not be more than 2/3.
  • Prefer dishes with liquid - soups, stews, casseroles, sauces. The slow cooker is perfect for that.
  • If possible, start the cooking process with an hour on "high" and then turn the controller to "low". This way, a safe temperature is reached faster.
  • If there was a power failure during the cooking time, do not continue the cooking process in the slow cooker. Cook the ingredients on the stove.
 

How do we test at askgeorge.com?

Live and authentic: We get the devices into our Hamburg test laboratory. Here we take a close look at everything.

Each test is preceded by an extensive search:

  • Which suppliers are on the market?
  • What current products are there?
  • What are the comparison criteria?
  • What tests are we going to run?
  • What is the test procedure?

When everything's settled, we'll bring the devices to us. For each product the test procedure, the measured values and product properties are documented in detail. We create photos and videos. We evaluate the results for you, summarize everything in a test report and calculate the test grade.

Have fun!

In the run-up to the test, we defined practical requirements and the following test criteria:

  • Handling
  • temperature control
  • heating
  • functional scope

In order to evaluate these criteria, we have defined several tests for the Slow Cooker. In these tests, pulled pork is prepared in all devices. First, the scope of delivery and functions are checked and the devices are pre-ranged according to the manufacturer's specifications. Each cooker is filled with 1.5 litres of water and 650 g of pork shoulder. As soon as the appliances are in operation, the temperature of the casing, handles and interior is measured at regular intervals.

The test runs are carried out at the "High", "Low" and "Keep Warm" levels. Once the meat is ready, the consistency is assessed. Handling, ease of use and safety are assessed throughout the test phase. Finally, the equipment is cleaned.

In order to avoid errors and to ensure the stress of everyday use, each test is carried out in several stages.

The test criteria are given percentages depending on their importance. The final score is then objectively calculated from the test criteria using an algorithm.

Product selection
Our product selection is based on observation of the current market. In addition to popular branded products, we also include insider tips in our selection. Criteria such as price and range of functions are an important factor for us. The test field is also determined by analysis and evaluation of customer reviews and external tests (e.g. Stiftung Warentest).

The devices are purchased anonymously or lent to us by the manufacturer. Dealers and manufacturers have no influence on the tests and our evaluation.

As soon as new relevant products come onto the market, our test field is extended by these. The new products go through the same test as the already tested devices.

Slow and thorough - With a slow cooker, meals are cooked over a long period of time. What advantages does this way of cooking bring? For which foods is the method suitable? How can cooking be varied? The following sections will answer these questions.

The term "Slow Cooker" is a modern term for a Crock Pot. Unlike a normal cooking process or preparation in a microwave, the slow cooker cooks to low temperatures for an extended period of time.

In principle, the "Crocky", as the Slow Cooker in America is also colloquially called, has a simple structure. It is an oval-shaped, electric cooking pot, which is covered in its interior with a layer of porcelain or fired ceramic. In contrast to a normal saucepan, a slow cooker has its own heating elements and is not dependent on a stove plate, so that the food can be heated. Instead, the pot is operated via the normal house current. Depending on the model, different cooking levels can be set and many crock pots also have adjustable time switches. This can be set exactly how long the food should be cooked before the slow cooker automatically turns off.

A slow cooker is about making the food so gentle that it can be consumed safely and at the same time remains tender and nutritious. To ensure this, the temperature in a slow cooker must never reach 100 ° C. The lowest temperature for most appliances is around 70 ° C. This temperature is sufficient to pass all food through completely. The highest temperature is in a slow cooker, however, in the rules at just under 90 ° C.

It certainly sounds seductive to prepare everything with a slow cooker, what you want to eat. After all, it's so easy: you pack all the ingredients in the device, set the temperature and looks after a few hours for the result. The likelihood is high that the meal is not as successful as one would have liked. This is because different foods have to be cooked in different ways.

The following meals can be prepared in a slow cooker without worrying about the result:

1) Soups & stews

Soups and stews are almost predestined for slow cooking. At such meals, it is all about the overall taste and neither an exact temperature nor a precise cooking time must be respected. That is why it is very easy to prepare a soup or a stew in a slow cooker.

2) Pot roast

Any meat product that is supposed to stew for an extended period of time is ideal for the crock pot. Due to the low fluid loss, the food remains very juicy even after a long cooking time and becomes so tender that it literally melts in the mouth. The Slow Cooker is therefore also considered an absolute insider tip in the preparation of Pulled Pork or Pulled Beef. This type of meat is said to be so very soft that it can be pulled into strips with a fork. For this, it is absolutely necessary that the meat keeps a lot of liquid and only gets cooked very slowly.

Slow Cooker end result
Slow-cooked pork makes it wonderful to make Pulled Pork.

With a slow cooker, this type of preparation is very easy, so even beginners with little effort can prepare their first pulled beef yourself.

3) Desserts

Desserts like creme brulee or rice pudding tend to burn quickly if the temperature gets too high. In a slow cooker, however, these desserts can be prepared with little effort and without the risk of boiling or burning.

4) Funds

A simple stock on meat leftovers, vegetable slices and maybe a few pieces of onion does not need much attention and can quietly simmer for several hours without supervision. Similar to a soup, a fond in a slow cooker can hardly fail and becomes an excellent base for sauces.

On the other hand, these foods are not suitable for cooking alone with the Slow Cooker:

1) Rice & Pasta

Cereal products like rice and pasta need a lot of attention to cooking as well as a lot of liquid. Again and again, these ingredients must be stirred and controlled for their strength. If they cook too long, they absorb too much liquid, which quickly turns them mushy. That's why it makes more sense to cook such foods in the traditional way.

2) Roast Chops, Meatballs, Roast Beef and Co.

Need a high temperature and a lot of practice. The meat should be well-fried and the meat should have a certain strength afterwards. For this, it is necessary that the food loses liquid. However, in a slow cooker, roasted meat would never be cooked in the same way as in a roasting pan or in a pan. The meat would be too soft and the taste would not be so good.

3) Baked goods

In order for pastries to succeed properly, temperatures of well over 100 ° C are usually necessary. Too low temperatures prevent dough from rising properly and instead of a cake you only get a heated dough. That's why pasta should be cooked in an oven instead of the slow cooker.

There are several things that speak for and against the use of a slow cooker. The biggest advantages of the kitchen utensil are:


Independence:

A slow cooker requires much less attention in cooking than other kitchen appliances. After being filled and set to the required cooking level, the Slow Cooker works independently, without having to worry about the preparation.


Security:

A slow cooker is safer compared to a saucepan. There is no burning and no overcooking. You do not have to worry about hotplates and you can even go outside for a few hours or let the crock pot run overnight without anything bad happening.


Energy saving:

Compared to a stove or a hotplate, a slow cooker is significantly more frugal in its energy consumption. On the one hand, this has to do with the fact that the cooking appliance only produces lower temperatures. On the other hand, less energy is lost in the closed slow cooker than in an open cooker.


For large quantities:

The big slow cooker has a capacity of 6,5l. This makes it very easy to prepare dishes for a larger group of guests without the effort being greater.


Good for vegetables:

Vegetables contain many vitamins that are good for your health. When cooking a large part of the vitamins is lost, because the nutrients are destroyed by high temperatures. In the Slow Cooker, on the other hand, vegetables can be cooked at much lower temperatures, so that most of the vitamins are retained.

Beginner-friendly:

With a slow cooker even beginners in the kitchen will succeed in a nutritious meal without much previous knowledge. All you have to do is wash and trim the ingredients. The rest is taken over by the crock pot.

In addition to these advantages, there are a few drawbacks to consider when using a slow cooker:

Few functions:

Compared to other kitchen appliances, a slow cooker is not very flexible. You can only cook food with it, while you can roast or cook with other aids such as a pan.

Time Intensive:

A slow cooker is not suitable for a quick meal in between. No matter what you want to cook - each cooking process takes time to thoroughly cook the ingredients.

Not for small households:

A small slow cooker can hold 3.5 liters. It should always be filled up to half to make it worthwhile to use the device. For a 2-person household this is often too much and inevitably means that part of the cooked meal has to be frozen.

Preliminary work necessary:

Not all ingredients of a meal can be cooked together in the slow cooker, as meat, for example, has a different cooking time than potatoes. As a result, many meals rely on boil-in of individual ingredients so they can cook at the same time along with the rest in the slow cooker.

Falling below the 100 ° C mark has an important background. 100 ° C is the temperature at which water begins to boil. As a result, water vapour emerges from the food and spreads in the air. Cooked ingredients such as meat lose texture due to this fluid loss and quickly become tough.

On the other hand, if the temperature in the cooking vessel does not exceed 100 ° C, significantly less liquid will escape from the food. As a result, the ingredients stay juicy and tender, even if they have to be boiled for a long time.

Slow Cooker end result
The meat is boiled until it almost decays by itself.

To ensure that the food can be cooked at all, a temperature of at least 70 ° C is required. This is because both meat products and some vegetables and fruits may contain substances that are incompatible with humans. So supposedly good products can contain germs or bacteria that are not recognizable to the human eye. Some foods, such as brussels sprouts, by their very nature, contain substances that can cause nausea or malaise when consumed. These substances serve as a natural defence against predators but have nothing to look for in a meal. In order to kill germs and bacteria and at the same time to decompose plant substances with negative effects, temperatures between 60 ° C and 70 ° C are already sufficient. With higher temperatures, the decomposition accelerates in addition.

In addition to the ingredients, recipe books also contain cooking stages and cooking times for the slow cooker. Although this information should actually be consistent, it sometimes happens that the prepared food does not succeed properly. There can be different reasons for this. Maybe the ingredients were not cut small enough. Or maybe the device that developed the recipes for the cookbook had different cooking levels. Regardless of the possible causes, there are ways to shorten or lengthen the cooking time of a slow cooker so that meals succeed as they should. To shorten the cooking time, these tricks help:

Other cooking levels:

Instead of the lowest level, try the medium or highest level to cook the higher temperature ingredients.

Smaller pieces:

If you cut your food into smaller pieces, they will cook even faster.

Pre-cooking:

Especially meat products should be sautéed in a pot or pan before cooking in a slow cooker. The cooking time is reduced significantly.

Warm instead of cold:

Adding cold liquids like a broth to the slow cooker will affect the cooking time. Accordingly, one can shorten the time a bit when working with warm liquids. To extend the cooking time, these tips help again:

Lower level:

If a dish is to be prepared at the highest or the middle cooking level, choosing the lowest cooking level instead can help. If a recipe uses the lowest level, you can also use the warm-up feature. In this case, however, the dish should be pre-cooked at least half of the original low-level cooking time before switching to the warm-up level.


Frozen Ingredients:

Although fresh ingredients are usually better, it helps prolong the cooking time by using frozen ingredients. The cooking time is extended by the time to thaw.


Coarser pieces:

The larger a piece, the longer it takes, until it is completely cooked. So if a dish gets too fast with chopped ingredients, then cutting it next time can make it coarser.

The process comes from a time when hotplates could not reach the temperatures that are possible today. To ensure that the meals could be cooked anyway, they were cooked in cast iron pots over a long period of time. With the advent of more modern cooking appliances, however, the slow speed was slowly forgotten and only became popular again in the 1950s with the presentation of the first crock pot in the USA.

The slow cooker got its boost in the 70s, as more and more women took their role as classic housewives and started to work. With less time to cook, crock pots were a real home-made relief and became a bestseller.

Conclusion

With a slow cooker, delicious meals can be prepared comparatively uncomplicated. There are a few things to watch out for. However, the handling is very beginner-friendly overall. If you pay attention to the things that have been dealt with in this text, then it will not be difficult to prepare the desired food. With the necessary amount of creativity, you can then develop your own recipes so that a slow cooker can quickly become an indispensable kitchen appliance.

In addition to slow cookers, we have also tested other devices that cook food gently. For a detailed review of Steamers, see here. Also with a Hot Air Fryer you can cook very gently and the vitamins contained in the food well, which is why these should also be considered.
