How to Clarify Used Cooking Oil
How to Clarify Used Cooking Oil will help you get the most use out of leftover oil after frying, searing, or sauteeing.
Ingredients
- 1 cup used cooking oil, cooled
- ¼ cup water
- 1 tablespoon cornstarch
Instructions
- Place a fine-mesh strainer over a heat-safe bowl and set aside.
- In a small dish, whisk together water and cornstarch to create a slurry. Set aside.
- Pour your used cooking oil into a large pot.
- Pour the cornstarch slurry into the pot with the used cooking oil.
- Heat this mixture over low heat. (You don't want it to simmer.) Occasionally, stir and scrape the bottom of the pot. This process takes about 10-12 minutes. You know it is done when the cornstarch has all come together, becomes a solid, and has collected all of the debris.
- Remove oil from heat and pour it into the fine mesh strainer. (You can also use a couple of layers of cheesecloth.)
- Discard the cornstarch mixture.
- Allow the oil to cool completely before storing. The oil will look cloudy at first but will settle as it cools.
- Refrigerate the clarified oil.
Notes
To clarify more than 1 cup of oil:
Measure how much oil you have in cups. Multiply the recipe by that number. If you have 2 cups of oil you will double the recipe.
