What Is Cornstarch and Why Substitute It?

Cornstarch is a fine, powdery starch derived from the endosperm of corn kernels. It’s prized for its neutral taste and excellent thickening power in hot liquids. When heated, cornstarch gelatinizes, creating a smooth, glossy texture in sauces and gravies.

However, you might need a substitute for cornstarch if:

• You don’t have any cornstarch on hand.
• You want to avoid corn products due to allergies or dietary preferences.
• You need a gluten-free thickener alternative.
• Your recipe calls for a different texture or cooking property.

The key to a successful substitution is choosing the right ingredient that matches the thickening strength and behavior of cornstarch.
