Cornstarch
Instant thickening power for silky sauces and crispy coatings, your gluten-free kitchen essential.
What it is
Cornstarch is a fine, powdery starch extracted from corn kernels. It's a naturally gluten-free ingredient that acts as a powerful thickening agent in cooking and baking.
How to use
Mix with cold liquid before adding to hot dishes to prevent lumps. For thickening, use 1 tablespoon per cup of liquid. Always stir constantly while adding to hot mixtures.
Flavor and texture
Cornstarch is virtually flavorless and creates a smooth, glossy texture when cooked. It thickens liquids without adding any taste or cloudiness.
Best uses
Perfect for thickening soups, gravies, and stir-fry sauces. Use in baking for tender cakes and cookies, or dust on chicken and fish for extra-crispy coatings when frying.
Storage & freshness
Store in an airtight container in a cool, dry pantry away from moisture.

| Frozen | 6-10 yearsindefinite storage if properly sealed |
Durations are for best quality. Safe to consume longer if no spoilage signs present.
Cornstarch readily absorbs moisture from air, causing clumping and reducing thickening power.
Cooking tip
Always make a slurry by mixing cornstarch with cold water before adding to hot liquids - this prevents clumping and ensures smooth results every time.
Interesting note
Cornstarch creates a stronger thickening power than flour - you only need about half the amount of cornstarch to achieve the same thickening effect.
