The method described aims to clean used cooking oil, not thicken it. The process of using cornstarch and water helps remove particulate matter and impurities, making the oil reusable for further cooking; this does not thicken the oil itself. If you want to know how to clean your old cooking oil, here is a suggestion:
Cleaning Used Cooking Oil with Cornstarch
This process focuses on clarifying and cleaning used cooking oil rather than thickening it. It helps remove food particles and impurities, extending the oil's lifespan.
- Prepare the Cornstarch Mixture: Mix 1 tablespoon of cornstarch with 1 cup of water until well combined and there are no lumps.
- Pour and Stir: Gently pour the cornstarch mixture into the used cooking oil. Stir well, ensuring the mixture is evenly distributed throughout the oil.
- Cook and Capture Impurities: Heat the oil and cornstarch mixture gently. As it heats, the cornstarch will coagulate and trap the grease and food particles.
- Strain and Store: Once the cornstarch has captured the impurities, carefully strain the oil through a fine-mesh sieve lined with cheesecloth or a coffee filter.
- Proper Storage: Store the cleaned oil in a sealed container, away from light and heat, to prevent spoilage. This will help maintain its quality for future use.
It is important to note that severely degraded oil should be discarded, as cleaning may not restore it to a usable condition. Always assess the oil's color, odor, and viscosity before attempting to reuse it.
