Why is My Beef Tallow Smoking? Common Causes Explained
Beef tallow is one of the most popular cooking fats for its flavor and high smoke point, and it is good for frying, roasting, and searing.
Smoking beef tallow, however, can spoil the taste of your food and may sometimes create health issues.
To get the best results, you need to know why beef tallow smokes and how to stop it from occurring.
In this article, we’re going to talk about why your beef tallow is smoking, some of the common causes, and how to put a stop to it.
What is Beef Tallow, and Why Does it Smoke?
Rendered meat fat from cows, most often from the kidney or other fat deposits around it.
At room temperature, it is solid and has been used for hundreds of years in cooking, being a natural alternative to today’s oils, as well as processed fats.
Beef tallow will begin to smoke when it gets to its smoke point, which is the temperature at which it starts to break down and smoke.
This is a big deal in cooking because when fat starts smoking, its flavor is gone, and it can release nasty stuff.
In order to use tallow properly in your kitchen, it is important to know what happens when it smokes.
How High is Beef Tallow’s Smoke Point?
Beef tallow has a smoke point of 375°F (190°C) to 400°F (204°C) (1).
Because of this, beef tallow is a great option for high-heat cooking like frying and searing since it can handle higher heat than some other cooking oils.
But every fat has its limits.
Tallow can start to break down when it reaches its smoke point, leading to bitter tastes and possibly dangerous chemicals like acrolein (2), which can irritate the eyes and throat.
This is why tallow cookery should be watched carefully to ensure the heat doesn’t rise above the smoke point.
There are several common causes of smoking in beef tallow.
A few things could cause your beef tallow to smoke before you expect it to.
The most common cause of this is overheating, which could be due to using too much heat or leaving the fat in the pan too long, and the temperature rises too high.
Impurities in the tallow, like food particles or moisture, can also cause early smoking and reduce the smoke point, making it another cause.
Lastly, smoking using low-quality beef tallow or tallow that has been improperly rendered can also lead to premature smoking.
The first step in solving this problem is to know the causes of your beef tallow's smoking.
Tallow’s Smoke Point
Heating the beef tallow to a temperature above its smoke point is one of the most common reasons for beef tallow smoking.
If you leave the tallow heating for too long, you can get it to this stage, or if you use high heat settings that cause the temperature to spike quickly.
This leads to the fat molecules breaking down and the tallow beginning to smoke, releasing unpleasant odors and flavors.
If you do not want to do this, always keep an eye on the temperature of the tallow and use a thermometer if you can.
Keeping your tallow within the suggested temperature range will assist you in maintaining the best cooking temperature for your tallow.
Contaminants in Your Tallow
Secondly, your beef tallow might smoke due to the presence of contaminants.
Food particles and moisture from reusing tallow, or unfiltered tallow, will bring down the smoke point of the fat.
This is because tallow contains impurities, which cause the breakdown of the fat at a lower temperature than it otherwise would (3).
Strain and filter your tallow before using it to avoid this, making sure you get out any leftover food particles or moisture.
It will help to keep the quality of the tallow and prevent it from smoking too soon.
Using Low-Quality Tallow
The quality of your beef tallow is going to play a big role in how it will behave when hot.
Poorly rendered or sourced tallow from animals not raised in natural, healthy environments will have a lower smoke point and more impurities.
While buying beef tallow, opt for products made from grass-fed beef, which are of better quality and will perform better in cooking (4).
Tallow that is of lower quality can smoke at a lower temperature, which isn’t ideal for cooking at very high heat.
To avoid this issue, invest in high-quality, well-rendered beef tallow that will give you a better cooking experience.
Beef tallow smoking is very common, especially if you use a wok or skillet with a loose-fitting lid.
The next section will discuss how we can stop beef tallow from smoking.
You can cook delicious food every time with a few simple precautions to keep your tallow smoking-free.
For Exact Heating, Use a Thermometer
The best way to prevent your beef tallow from smoking is to know how hot it is.
An easy and effective way to guarantee your tallow does not go past the smoke point is with a thermometer.
Knowing the exact temperature of the fat allows you to avoid overheating it and ensure it does not smoke.
When using beef tallow to cook in a pan or deep fryer, try to operate the temperature between 375°F (190°C) and 400°F (204°C).
Strain and Filter Your Tallow
When using beef tallow, it should be strained first to remove any impurities, such as food particles and moisture, before use.
If you are rendering beef tallow at home, it’s easy to end up with small bits of meat or skin in the fat.
The fact is that these bits can cause the fat to break down at a lower temperature, which can cause smoke.
If you strain your tallow through a fine mesh sieve or cheesecloth, you make sure you are using only the purest fat in your cooking and reduce the chance of smoking.
Avoid Reusing Tallow Too Often
It may be tempting to reuse the beef tallow after frying, but this will eventually cause smoking problems.
Every time you heat tallow, you’re breaking it down a little bit more and reducing its smoke point (5).
If you reuse the same tallow, it will eventually smoke at lower temperatures and ruin the flavor and quality of your food.
Rather, attempt to dispose of applied tallow appropriately and utilize fresh tallow each time you cook.
If Your Beef Tallow Starts Smoking, What to Do
If you see your beef tallow smoking, don’t freak out.
Fortunately, there are a few simple things you can do to save the situation.
Turn Down the Heat Immediately
Your beef tallow will start to smoke if you have it on too high a heat, or in fact, if it is any sort of fat. So the first thing you should do is turn the heat down or turn the pan off the burner altogether.
It will cause the fat to stop breaking down further, and smoking more.
When the temperature goes down, there will be no problem continuing to cook.
Ventilate Your Cooking Area
- Beef tallow starts smoking very quickly and can quickly fill your kitchen with unpleasant smoke.
- Make sure your kitchen is well-ventilated to prevent this from becoming overwhelming.
- Open windows and turn on your exhaust fans to allow smoke to escape.
- It will clear the air and make your cooking environment more comfortable.
How to Salvage Your Smoked Beef Tallow
If you've already smoked your beef tallow, you can still use it, but it may not be great for frying or high-heat cooking.
Instead, use the smoked tallow in recipes where the flavor of the smoke would enhance the dish, such as in sauces or baked goods.
Alternatively, you can throw the smoked tallow and begin again with a new batch for better results.
Final Thoughts
When cooked correctly, beef tallow is an incredible cooking fat.
If you understand its smoke point and know how to prevent it from smoking, you’ll be able to cook better and dodge problems.
Just be sure to watch the temperature, strain your tallow, and make sure you’re buying good stuff so it does not smoke.
Following these tips will help you use beef tallow with confidence and make some delicious meals every time.
