Can You Mix Different Oils in a Deep Fryer? (Explained)

A deep fryer is a kind of kitchen appliance that is used for deep frying. And obviously, deep frying requires an immense amount of oil.

It’s feasible if you haven’t given much thought to mixing oils for deep frying yet. In a deep fryer, you can combine your oils.

Deep frying necessitates a lot of oil, and you may not always have enough of one type of oil in your kitchen. You may feel compelled to combine one or two types of oil for deep frying at certain times.

In certain cases, you can use a combination of oils in your fryer rather than getting more from your local grocery shop. Let’s learn more about mixing oils in a deep fryer and broaden our culinary horizons.

Can you mix different oils in a deep fryer? 

You can mix different oils in a deep fryer. Mixing oils is not something to be worried about in your kitchen as long as you are doing it correctly. You must know the smoke point of the oils you are about to mix. And the reason is that it will provide you with the perfect combination for deep frying.

Can you mix two different oils in a deep fryer?

Yes, you can mix different oils in a deep fryer. In the case of mixing oils, the smoking points of the oil are the most crucial terms. There’s no harm in combining two oils with identical smoke points. Although, it’s critical to keep an eye on the smoke point.

When you deep fry something, the oil’s smoke point must be high; otherwise, the food will not be cooked and your oil will entirely burn off, leaving you with only the uncooked food in your fryer. Using two different oils with equal smoke points is therefore acceptable.

Is it OK to mix two oils for deep-fat frying?

Yes, Of course, it is! Submerging food into very hot oil and fry it till it reaches a certain temperature and is deep-fried is called the deep-fat frying process. This particular process needs a lot more oil than regular deep frying.

Most of today’s deep fat fryers need around 5 to 20 cups of oil. Also, there isn’t any significant difference between the regular frying process and the deep-fat frying process.

So, just like the regular deep frying process, you can mix two oils for deep-fat frying and get away with it.

What are the effects of using different oils in deep frying?

Using various oils to fry your food in the proper manner is something to keep in mind. To complete the frying process, we know that oils with equal smoke points are required.

So, if you blend a 450°F oil with a 225°F oil, the lower one will burn off faster and contaminate the food. The food will have a burnt aftertaste. So, if you don’t know what kinds of oils you can blend, your Sunday night chicken fries aren’t going to impress your pals

What oils can you mix in a deep fryer?

You can almost mix any type of oils in a deep fryer except for a few exceptions. You have to remember that mixing oils mostly depends on their smoke points. Here are some recommendations on mixing oils that you might try:

Canola oil and coconut oil:

Canola oil and cottonseed oil have almost identical smoke points, 400°F and 420°F respectively.

Your deep fryer’s oils need to surpass the 320°-350°F mark to make the deep-frying process work. Both of these oils live up to the mark, which makes them a good option to mix.

Peanut oil and sunflower oil:

Peanut oil and sunflower oil together is a good mixture for deep frying. Both of them have the same smoke points of 450°F.

Also, both of these oils cost you very little, so you don’t have to worry about spending a ton of money on them.

Soybean oil and corn oil:

Soybean oil is the perfect oil for frying almost any type of food and corn oil is the cheapest option for you to use in a deep fryer.

But the best thing about these two is that you can mix them in a deep fryer because both of them have 450°F smoke points.

Can you add new oil to old oil in a deep fryer?

Yes, you can add new oil to old oil in a deep fryer. Just because deep-frying takes a lot of oil, it becomes essential to reuse the old oil because otherwise a lot of oil will be wasted each time you use a deep-frying process.

So, sometimes you have to use old oil with the new oil. That is completely fine and nothing to be worried about. Reusing old oil with new oil is not going to change how your food is going to taste.

But the process has to be precise. You cannot add old oil to new oil without filtering it out first.

You can’t also add old oils that have already been used a lot of times in your new oil because older oils have a thicker consistency that can potentially ruin your food by making it very greasy. You can add old oil that has been used just once or twice to your new oil though.

What is the best oil for deep frying?

Deep frying oil selection is crucial to the whole process. We already know that the oil temperature has to be 320°-350°F in order to fry something. So any oil that has a smoking point above that is okay to choose for deep frying.

There are a lot of oils that match that description. So, which one you should choose is totally up to you. Most people choose canola oil or soybean oil or sunflower oil. These are called vegetable oils and are the best oils for deep frying.

Vegetable oils don’t necessarily have strong flavours of their own (except for olive oil) which is exactly what we are aiming for. So, they are perfect for deep frying.

Can I mix shortening and vegetable oil?

Yes, sounding as astonishing as it is, you can mix shortening and vegetable oil for deep frying. Shortening is solid fat at room temperature and can be used in deep frying.

You can mix it with vegetable oil without being concerned. Shortening doesn’t have any flavour of its own. Therefore, it won’t affect your food by altering its flavour. 

Shortening may have a low smoke point, which is about 360°F, but deep frying with it is possible while mixing it with vegetable oil.

Can you mix canola and olive oil in a deep fryer?

No matter how good canola oil is for deep frying, olive oil may not be the best oil to mix with canola oil for deep frying, even though it is a kind of vegetable oil.

Olive oil is not cheap and has a low smoke point(320°F). So, olive oil is not the best oil out on your kitchen shelf for deep frying.

Mixing it with canola oil shouldn’t be considered as well. Olive oil has a very dominant flavour that can alter your food’s flavour while deep frying. So mixing olive oil with canola oil is not a great idea.

Can you mix vegetable oil and canola oil when deep-frying?

Canola oil and vegetable oil are considered the best oils for deep frying. But you may be curious if they can be mixed. To simply quench your thirst for curiosity, you can mix canola oil and vegetable oil to deep fry. Both have similar smoke points.

Canola oil starts burning off at 450°F and vegetable oil at 430°F. Both have almost no flavour of their own. In a word, they are perfect for mixing when deep frying.

Can you mix peanut and vegetable oil for deep frying?

Deep frying can be done with a mixture of peanut and vegetable oil. But there’s a catch. Peanut oil has a strong flavour compared to vegetable oil or canola oil.

Mixing peanut oil with vegetable oil for deep frying may yield a subtle change in the taste of the food. So using peanut oil has to be limited.

If you are a little short on vegetable oil, you can add some peanut oil. Moreover, peanut oil’s smoke point is 450°F which is compatible to mix with vegetable oil when you are deep frying.

Final Thoughts: 

Mixing oils for deep frying doesn’t have many limitations. So, the mixing of oils can be of any type, depending on their smoke point. It is probably the only major factor, only second to the added flavour of the oils, to be taken in before mixing oils for deep frying.
