Begin by measuring 2 tablespoons of cornstarch and placing it in a small bowl.
Add 2 tablespoons of cold water to the bowl containing the cornstarch.
Stir the mixture with a wire whisk until the cornstarch is completely dissolved, and turns into a smooth paste.
Gradually introduce 1 cup of water to the cornstarch paste this will make it more runny and easier to pour in recipes.
Continue stirring until the slurry is thoroughly combined and free of any lumps.
Your cornstarch slurry is now ready for use!
Notes
You don't have to add additional water to the slurry. It just makes it easy to add to a recipe. Most recipes are gone to tell you the amount of water and corn starch to mix to make your slurry, so follow the recipe.
Generally, if you are trying to thicken something like a soup, I start with 2 tablespoons of cornstarch and 1/4 cup of cold water for my slurry and let it go in the dish before adding more.
This is great as a thickening agent in sauces, soups, or other recipes that need thickening. When mixing the slurry into your dish, add it slowly to prevent clumping.
Cornstarch is a safe option for those with gluten sensitivities.
