In the test: Cosori Dual Blaze hot air fryer with 6,4 liters

I have to say, I haven't tested an Air Fryer before and this device category doesn't have too much to do with Apple either, but I know from past conversations that you can also read reviews from tape dispensers, spider fishing gear, camping tables or insect bite healers happy. Therefore: Welcome to the test of the Cosori Dual Blaze 6,4 liters.

At this point I would like to thank Cosori for providing the device. The companies send me devices here and there for reviews, but the posts go online without the companies being able to see or influence them beforehand. I want to write honest reviews and I am committed to you and no one else.

This time the Cosori Dual Blaze hot air fryer is being tested in practice (photos: Sir Apfelot).

Using the volume meter, I was able to find out that both hot air fryers are pretty much equally loud or quiet.

Non-stick coating on basket and crisping tray

One more note about the cooking basket: This is made of aluminum with a plastic handle that doesn't get warm. Both the cooking basket and the "crunchy tray", as the manufacturer calls it, have a non-stick coating and are easy to clean.

So that the crispy tray does not scratch the non-stick coating of the basket, the feet of the tray are covered with silicone.

Both the cooking basket and the crispy tray, as Cosori calls the insert, have a non-stick coating.

XXL Air Fryer with 6,4 liters cooking area

One thing that is immediately apparent in the product name is the mention of the 6,4 liters available in the frying basket. Of course, you can't fill the entire volume with fries, but you do have an impressively large area on which to lay out your groceries.

We currently have a hot air fryer with two small frying baskets, which is of course good if, for example, you want to make fish fingers in one basket and vegetable sticks in the other, but you couldn’t get a lot of fries there because the two small baskets are still smaller are as the one large basket of the Cosori Dual Blaze.

In this photo you can see our old Air Fryer with two small compartments on the left and the space available with the Cosori on the right.

Two heating coils

The other special feature that can be found in the Cosori hot air fryer are the two heating loops that are attached above and below the cooking basket. This ensures that the food also gets enough heat from the underside and does not just brown on one side.

With our other hot air fryer, for example, you always have to shake the fries after about 12 minutes so that the top ones don't turn brown while the bottom ones stay light. The second heating coil is intended to help against this.

The Cosori Dual Blaze has two heating coils that ensure even heat distribution - practical for rolls and pizza (photos: Sir Apfelot).

A word about the app and the recipe book

Since the Cosori Dual Blaze is a "smart" hot air fryer, there is also an app for the device. These can be downloaded from the App Store and the Play Store and then installed.

You can use the app to look at recipes offered by the manufacturer, but you can also set the temperature and cooking time or choose a preset. The small catch is that you have to start the cooking process manually with the device. For safety reasons, it is not permitted to start the fryer remotely.

The VeSync app is the control center for various smart devices, including the Cosori hot air fryer. I didn't use it further because the function is very limited and I don't need any "smart" functions.

Here is the information on the product page:

Warning: According to safety standard IEC/EN 60335-2-9, the Smart Air Fryer “Start” button should be pressed manually. Then you can control it remotely via the APP.

But I don't find that tragic, as I find it far too cumbersome to open an app to make the settings, which I did much faster directly on the device.

Second, I'm not a great cook, so I don't try all these recipes, just doing the obvious with the deep fryer:

build buns
bake pizza
Bake chicken nuggets or fish fingers
Build up pretzels or rolls
fry fries

According to the recipe book, however, you can cook and bake things with the right accessories, which you can also order with the Cosori Dual Blaze, as is possible in the One-Pot. All of this works well according to Amazon reviewers, but I haven't tried it.

The enclosed recipe book contains recipes in different languages and surprises with dishes that you wouldn't have expected from an air fryer.

My experiences

Before I give my conclusion on the Cosori Air Fryer, I would like to briefly describe my experiences with the device. But let's start with a small point of criticism.

Criticism: Two holes in the crispy tray

French fries are without question one of the most popular dishes to make in an air fryer. That's why I tried it several times (and because I like to eat fries). What I immediately noticed was that there are two finger holes built into the crispy tray that you put in the bottom of the cooking basket, which are supposed to help get the tray out of the basket again.

The crisping sheet has two holes in the middle to remove it. Unfortunately, some fries always fall in there, which then do not come out when emptying.

So far so good, but what unfortunately happens all the time is this: You spread the fries on the tray and some of them disappear into the holes. It's kind of impractical.

I found the tip on the internet to stuff two balls of baking paper into the holes each time. That may work, but it's somehow not an elegant solution. Maybe you could have included two silicone plugs.

How are fries made in the Cosori XXL?

The result after the "French fries program" looks quite good. Normally I would have shaken the fries halfway through, but the manufacturer advertises that the fries also turn brown all over.

In fact, you also notice that the fries are supplied with bottom heat. They definitely don't brown as much in my other air fryer unless I flip them. But I think I would shake them up in the Cosori in the future as well, because that way the tips of the fries don't turn so brown, which tends to happen with all hot air fryers.

The fries in the Cosori are definitely better than in our other hot air fryer - but unfortunately that doesn't really come out in the photo.

Ready-made pizza fits perfectly and is delicious!

One of the reasons why I wanted to try the 6,4 liter Cosori XXL is because other customers said it could be used to make a ready-to-serve pizza.

But you have to use a little trick to make it work, because if you put it in the cooking basket deep-frozen, it will be crooked because it won't fit veeeeery right.

But instead of shortening the curves of the pizza, you can simply put it in at an angle and let it run for 2 minutes in the pizza program (bake). The edge has then thawed and the pizza has slipped into position and lies flat on the bottom.

Here's the ready-made pizza, which I pimped with cheese - before baking.

Now you cover them if you want to "pimp" them with other ingredients and send them back into the oven. After a good 10 to 12 minutes, the pizza is nicely brown and ready to eat.

By the way, I baked them without a crispy tray so that the heat comes directly through the tray to the bottom of the pizza. That has worked well so far.

My expertise in food photography is pretty much non-existent, but I think you can tell the pizza is done and done.

Pizza in the Air Fryer - really saves electricity

I admit, it's not that easy to get the pizza out of the steamer and it's more elegant to make it in the regular oven. However, it is worth using the Air Fryer if you only want to make a pizza, because you save a lot of electricity.

For one thing, there is no heating up. The "space" in the Air Fryer is so small that it reaches full temperature in less than a minute. This alone easily saves us 5 minutes of cooking time.

Our convection oven consumes a whopping 1700 watts instead of 2700 watts (like the Cosori) - a clear difference that also costs money.

On the other hand, the power required to get the same temperature is significantly lower. While the Cosori hot air fryer works with 1700 watts, my power meter showed me that our oven needs 1000 watts more (2700 watts).

With current electricity prices, you might save 5 to 10 cents per pizza, which isn't much, but in the long run you'll save quite a bit if you use the device more often and also bake rolls or other dishes. And last but not least, the food is on the table faster and you save resources.

Officially everything from the Cosori is dishwasher safe. In the long run, harsh cleaning is not good for any plastic, which is why I prefer to clean by hand.

Build up pretzel rolls

Every Air Fryer bakes normal rolls well, because they usually don't have to rise. That's why pretzel rolls are level 2 of the roll-baking discipline, so to speak: they have to rise during the baking process and also be done on the inside so that they taste good.

Our old hot air fryer has the problem that it doesn't get enough heat from below, despite the crispy tray. As a result, I had to turn them several times during baking so that they got a reasonably even heat, but there was always some dough inside that was still more or less raw.

The unbaked pretzel rolls on the crispy tray of the Cosori Dual Blaze.

I also used the Cosori hot air fryer with the crispy tray and to test the performance, I didn't turn the rolls, but baked them continuously for about 10 minutes at 160 °C.

Buns are definitely ready faster in the Cosori Dual Blaze than in any oven because there is no preheating time.

The result was not 100% perfect, but 95% good. I could still make out small areas in the bun that looked like the dough could have baked another 1-2 minutes, but there was no noticeable taste.

Inside you can still see that the dough might have needed 1-2 minutes longer, but the rolls tasted normal.

The bottom line is that the Cosori is much more suitable for "fresh" rolls than other hot air fryers without a hot spiral under the cooking basket.

Pan replacement for fried potatoes and Co.

Something I haven't tried myself, but seems to work well too, is using the air fryer as a frying pan. I saw this in the video by YouTuber "Rizzo Life":

https://www.youtube.com/watch?v=q_vB3o6PTq8

I've also made normal pieces of potato in the Cosori, but I've never worked with that much fat. But of course this helps to brown the onions nicely.

In the Cosori recipe book you will also find numerous other recipes that go far beyond normal "frying". For most of these recipes one will though the larger set of the Cosori fryer have to buy it, but I didn't.

The Cosori fryer looks elegant and also has great inner values - you can't go wrong with the purchase.

My conclusion on the Cosori Dual Blaze

With 6,4 liters of cooking space, the Cosori Dual Blaze is one of the larger models in hot air fryers. The two heating coils, which are attached below and above the cooking basket, achieve noticeably better heat distribution.

You can compensate for the poorer heat distribution in other hot air fryers, for example by shaking the fries in the basket after 10 minutes, but you can't shake a pizza much.

This means that if you would like to make a frozen pizza every now and then, the Cosori deep fryer could be a good choice. Just be aware that larger pizzas won't fit in there.
