7 Simple ways to reuse cooking oil

Cooking oil is one of the main ingredients used in day-to-day cooking. In most households and commercial kitchens, cooking oil is reused several times, which may pose serious health concerns. However, some experts feel that reusing cooking oil after taking proper measures can help in reducing wastage and also makes the oil fit for consumption. Here are seven simple ways to reuse cooking oil effectively.

Filter and Store
After frying or sautéing, you can filter used cooking oil to remove food particles. Let the oil cool down, then pour it through a fine mesh strainer or cheesecloth into a clean, dry container. Store the filtered oil in a cool, dark place, preferably in an airtight glass jar or bottle. Be sure to label it with the date and type of oil. This method allows you to reuse the oil for similar cooking methods, such as frying or sautéing.

Homemade Salad Dressings
Used cooking oil can add a unique flavor to homemade salad dressings. For instance, oil that has been used for frying garlic or herbs can enhance the taste of vinegars. Combine the used oil with vinegar, mustard, herbs, and spices to create a delicious dressing. Just ensure that the oil has not been overheated or burned, as this can impart an unpleasant flavor.


Infuse Oils for Flavoring
You can infuse used cooking oil with additional flavors by adding fresh herbs, garlic, or spices. Simply heat the used oil gently with your chosen ingredients for about 30 minutes, then strain the oil into a clean container. This infused oil can be used for drizzling over dishes, enhancing the flavor of salads, or as a base for marinades.

Use in Baking
Many baking recipes call for oil, and you can substitute used cooking oil for fresh oil, especially if it’s neutral-flavored like canola or vegetable oil. Just keep in mind the type of oil you have used; for example, oil used for frying fish may not be suitable for a sweet cake. Ensure that the used oil is still fresh and hasn’t been overheated before incorporating it into your baked goods.

Create homemade soap
Used cooking oil can be transformed into homemade soap. The process involves combining the oil with lye and water, then allowing it to saponify. This method not only repurposes oil but also creates a gentle, biodegradable product. There are many recipes available online for making soap at home, but it’s essential to follow safety precautions when handling lye.

Oil for Lubrication
Used cooking oil can serve as lubricant for various household tasks. It can be used to lubricate squeaky hinges, garden tools, and other mechanical parts. Simply apply a small amount to the area that needs lubrication and wipe off any excess. However, be mindful not to use it in areas where food safety is a concern.

Composting and fertilizing
While you should avoid adding large amounts of used cooking oil directly to compost as it can create odors and attract pests, small quantities can be mixed into compost or used to create a homemade fertilizer. The nutrients in the oil can benefit soil health. Another option is to mix the used oil with other organic materials to create a nutrient-rich composting mix. Just ensure that you’re using it in moderation.
