For thickening, you generally need less cornstarch than flour; a good rule of thumb is to use half the amount of cornstarch compared to flour for the same thickening effect. This substitute works well in dishes like soups, stews, and pie fillings where a thick, clear consistency is desired. When using cornstarch, it’s best to mix it with a little cold water first to prevent lumps and ensure an even distribution.
How much cornstarch should I use to thicken sauces or soups?
When thickening sauces or soups with cornstarch, a good rule of thumb is to start with about 1 tablespoon of cornstarch mixed with 1 cup of cold liquid for every cup of hot liquid in your recipe; this cornstarch slurry helps prevent lumps. If you need a stronger thickening effect, you can gradually increase the amount of cornstarch, but be cautious as too much can make the sauce or soup excessively thick and give it a slightly starchy taste. For a creamier texture, mix the cornstarch with a small amount of cold water or broth before whisking it into your sauce or soup to ensure it disperses evenly and thickens smoothly.
Can cornstarch be used as a facial powder?
Cornstarch can be used as a facial powder due to its natural absorbent properties, which help to control oil and shine on the skin, making it a popular alternative to traditional talcum powders.

For best results, apply cornstarch to slightly damp hair, as this can enhance its absorbent properties. Remember to use a fine-tooth comb or brush afterward to remove any visible powder, ensuring a natural finish.
Can cornstarch be frozen?
Cornstarch, a common thickening agent in many recipes, can indeed be frozen, but it’s important to handle it correctly to maintain its quality. To freeze cornstarch, place it in an airtight container or a freezer-safe, sealed plastic bag to prevent air and moisture from seeping in, which can lead to clumping or degradation. It’s best to use frozen cornstarch within a few months for optimal effectiveness. While freezing doesn’t affect its thickening properties, it’s recommended to let it come to room temperature before using it to avoid any texture issues. This method can be particularly useful when you have leftovers from a bulk purchase or need to ensure a steady supply for future cooking needs. Freezing cornstarch is a practical solution for prolonging its shelf life and maintaining its usability.
Can cornstarch be used instead of baby powder?
