What is the proper way to use corn starch to thicken sauces?

Question

How do you mix corn starch slurry and how do you use it?

• Do you add the corn starch to the water, or do you add water to the corn starch?
• Generally what proportions do you need, what is the ratio of water to cornstarch?
• Do you need to use more slurry to thicken more liquid; if so, what is the quantity per volume?

Answer

I usually start small, with maybe a teaspoon of starch and a tablespoon of water. I guess that's roughly 2/1 water to starch by volume.

You do need more starch slurry for more liquid, but I advocate for going cautiously and starting with a single "dose" and then seeing if it's enough.
