About Cornstarch

What it is

Cornstarch and similar starches thicken sauces and gravies in cooking — and play a quiet second role as dry shampoo, baby powder, and itch-relief poultice off the stove.

Key thing to know about Cornstarch

Always mix into cold water first before adding to hot liquid — otherwise clumps. For dry shampoo on darker hair, mix 50/50 with cocoa powder.

1 tbsp cornstarch + 2 tbsp cold water = slurry for thickening 1 cup hot liquid; equal-parts paste with water for sting; sprinkle dry on hair roots

These are the most common uses for Cornstarch. Each card explains what to do, why it works, and what to notice.

How to use Cornstarch for thickening and dry uses

Make a slurry: 1 tablespoon starch + 2 tablespoons cold water. Whisk into a hot liquid to thicken.

Why it works for thickening and dry uses
