Mixing the Corn Starch Slurry
The process of cleaning your used cooking oil with corn starch is simple and easy. You will need 1 tablespoon of corn starch, ¼ cup of water, per 1 cup of used cooking oil. In a small bowl or measuring cup, mix the cornstarch and water together until it forms a slurry. This slurry will act as a natural clarifying agent, helping to remove any impurities or food particles that may be present in the oil.
Heating the Used Cooking Oil and Adding the Corn Starch Slurry
Next, turn on the heat to medium-low. It's important to start on medium-low heat to prevent splattering and fire hazards that can happen when adding water to oil on high heat. Slowly add the corn starch slurry to the oil and stir constantly. This will ensure that the corn starch is evenly distributed throughout the oil. Stir the mixture for 2 minutes, then increase the heat to medium and continue stirring for several more minutes.
Stirring and Straining the Used Cooking Oil
As the mixture heats up, the corn starch will begin to thicken, which will help to remove any impurities or food particles that may be present in the oil due to frying. The thickening of the mixture is due to the starch granules in the corn starch absorbing the impurities in the used cooking oil. This process effectively traps the impurities, making them much easier to remove from the oil. The mixture will begin to thicken as it reaches the right temperature and with enough stirring.
Once the mixture becomes gel-like, it's time to strain the used cooking oil and corn starch slurry. To do this, use a fine mesh strainer to strain the used cooking oil into a clean container. Be sure to strain it while it is still hot.
The newly cleaned oil is now ready for use. Repeat the process as needed. It's important to note that this method works best for oils that have been used for frying, but not for oils that have been used for baking or deep-frying. Additionally, it is worth noting that this method allows for cleaning and reusing cooking oil up to 3 times before discarding it. This not only saves money but also helps reduce waste.
Alternative Ways to Clean Used Cooking Oil
While our corn starch method is undoubtedly effective, it's not the only way to clean and reuse your cooking oil. Below are a few alternatives, using different tools and techniques to suit your specific needs and preferences.
Cooking Oil Filter
A cooking oil filter is a handy tool to have in your kitchen. They're designed to strain out particles as small as a single micron, ensuring your oil stays clear and fresh. You simply pour your used oil through the filter, and it does the hard work for you.
Using a Fine Mesh Strainer
If you don't have a dedicated oil filter, a fine mesh strainer can work just as well. This method requires a bit more effort, as you may need to strain your oil several times to remove all the impurities. Pairing your strainer with a cheesecloth can further enhance the filtering process.
Deep Fryer Oil Strainer
For those using a deep fryer, an oil strainer can be a game-changer. These are typically larger and more durable than regular strainers, making them perfect for filtering larger quantities of oil.
Filtering Oil with Coffee Filters
Coffee filters can be used as an inexpensive and readily available alternative for filtering cooking oil. Place a filter over a clean container and slowly pour the used oil through it. This process might be slow, but it's highly effective at removing even the tiniest of particles.
The method you choose ultimately depends on the tools you have at hand and the time you're willing to invest. The goal, regardless of the method, is to ensure that you're reusing clean, fresh oil that's free of impurities, and ready for your next cooking adventure.
FAQs About Clean Used Cooking Oil
Navigating the ins and outs of handling and reusing cooking oil can be a bit tricky, especially for those new to the concept. So, let's delve into some commonly asked questions related to reusing and filtering cooking oil, changing deep fryer oil, and more.
Can you reuse vegetable oil?
Absolutely! Vegetable oil can indeed be reused, especially when you've used it for frying. However, it's important to clean it properly between uses to ensure the flavor of your dishes isn't compromised. Our method of cleaning used oil with a corn starch slurry is particularly effective for vegetable oils.
How often should you change the oil in a deep fryer?
The frequency of changing your deep fryer oil depends on various factors, such as the type of oil used and the foods you've fried in it. As a general rule, you should change the oil after 6-8 uses. However, if the oil starts to foam, produces a foul smell, or turns dark, it's time to change it, regardless of how many times it's been used.
What does it mean to filter cooking oil?
Filtering cooking oil involves removing small particles and impurities from the oil that can affect its taste, color, and smell. There are several ways to filter oil, but one common method is to use a strainer or a specialty cooking oil filter. Our corn starch method is an easy and effective way to filter cooking oil at home.
Can you reuse deep fryer oil?
Yes, deep fryer oil can be reused. However, given the intense heat it is subjected to, it generally degrades faster than oil used for pan frying. Therefore, it's especially important to filter and clean deep fryer oil between uses. Also, always check for any signs of degradation, such as darkening color, bad smell, or excessive foaming.
