What is Cornstarch?
Cornstarch is a fine, white powder made by extracting the starchy endosperm from corn kernels. Due to its neutral flavor and excellent thickening properties, cornstarch is a common ingredient in numerous culinary, household, and personal care applications.
Essential Culinary Uses for Cornstarch
Cornstarch is a beloved staple in the culinary world, prized for its ability to produce glossy, smooth textures and crisp coatings. Here are the most popular ways to use cornstarch in the kitchen:
1. Thicken Sauces, Gravies, and Soups
- Cornstarch is a go-to thickener for gravies, pan sauces, soups, and stir-fries.
- For best results, dissolve cornstarch in cold water to create a “slurry” before adding it to hot liquids. This prevents lumps and ensures an even, glossy finish.
- Typically, 1 tablespoon of cornstarch thickens about 1 cup of liquid.
- Use cornstarch for a clear, smooth sauce in contrast to the slightly cloudy effect of flour.
2. Perfect Pie Fillings and Fruit Compotes
- Add cornstarch to fruit pie fillings, puddings, and compotes to achieve the ideal, sliceable texture.
- Unlike flour, cornstarch yields a glossy, translucent finish that showcases vibrant fruit color.
- For pies, use roughly 1 to 2 tablespoons of cornstarch per cup of fruit, depending on the juiciness of the produce.
3. Make Crispy Fried Foods
- Cornstarch is an essential ingredient in Asian-style stir-fried meats, tempura, and fried chicken or shrimp coatings.
- It forms a delicate, wispy, and ultra-crispy crust when used alone, or can be combined with flour for more structure.
- For gluten-free frying, use cornstarch by itself to coat proteins or vegetables before frying.
4. Lighten Baked Goods by Making Cake Flour
- If you don’t have cake flour on hand, substitute by mixing cornstarch with all-purpose flour (replace 2 tablespoons of each cup of flour with cornstarch).
- This helps create softer, more tender cakes by reducing gluten development.
5. Achieve Fluffy Omelets and Waffles
- A small spoonful of cornstarch in omelet or waffle batter helps trap steam, yielding a lighter, airier result.
- Try adding 1/2 to 1 teaspoon of cornstarch per batch.
6. Egg Substitute for Vegan Baking
- Cornstarch can replace eggs in many baked goods and batters.
- Mix 1 tablespoon cornstarch with 3 tablespoons water to mimic the binding and moisture of one egg (ideal for cookies, cakes, muffins, and pancakes).
Household Uses for Cornstarch
Beyond the stovetop, cornstarch serves as an affordable and non-toxic cleaner, deodorizer, and even a beauty aid. Explore its many household applications:
7. Shine Up Silver and Clean Surfaces
- Use a thick cornstarch paste (mixed with water) to polish silverware; let it dry, then buff to a shine.
- Sprinkle dry cornstarch on wood to remove grease residues or furniture polish build-up.
- Mix cornstarch with water and spray on glass, then wipe for a streak-free finish.
8. Untangle Tight Knots
- Struggling with a knotted shoelace or necklace chain? Sprinkle cornstarch on the knot and rub gently to help the fibers slide apart more easily.
9. Remove Grease Stains
- Cornstarch is adept at absorbing grease and oil stains from clothing, upholstery, and textiles.
- Sprinkle a generous amount of cornstarch on the spot, let sit for at least 15 minutes, then brush or vacuum it away. Repeat if necessary.
10. Homemade Dry Shampoo
- Blend 2 parts cornstarch with 1 part baking soda for a quick DIY dry shampoo solution.
- Dust onto roots with a brush, wait a few minutes to absorb oil, then brush out thoroughly for refreshed hair between washes.
11. Soothing Sunburn and Skin Irritations
- Make a cooling paste for sunburn relief by mixing cornstarch with water and applying gently to affected skin.
- Sprinkle cornstarch on bedsheets before sleep to reduce friction and discomfort from sunburn.
- Cornstarch can also be used as a poultice to relieve insect bites or mild rashes—let it dry on the skin, then brush away.
12. DIY Deodorant
- For a natural and effective homemade deodorant, combine equal parts cornstarch and baking soda; apply with a cotton ball or brush as needed.
- This is especially helpful for sensitive skin or individuals undergoing treatments where commercial deodorants cause irritation.
13. Prevent and Soothe Blisters
- Sprinkle cornstarch on your feet before putting on shoes, especially when going sockless, to reduce friction and moisture and thus prevent blisters.
- If a blister does form, cushion it appropriately and keep the area dry and protected.
14. Pet Grooming and Cleaning
- Rub cornstarch into matted fur on dogs or cats to help detangle and make brushing easier.
- Works as a gentle, absorbent cleaner for pets between baths.
Fun and Clever Projects with Cornstarch
Thanks to its unique properties, cornstarch is a favorite material for crafts, science projects, and even stress relief activities.
15. Homemade Slime and Oobleck
- Make your own Oobleck—a non-Newtonian fluid famous from Dr. Seuss—that is both a solid and a liquid under different types of pressure.
- Mix 2 cups cornstarch with 1 cup water (add a few drops of food coloring), and watch it transform as you handle it.
- Fun, safe, and easy for children’s sensory play or home science experiments!
16. Homemade Baby Powder
- As an alternative to commercial powders, pure cornstarch can serve as a mild, fragrance-free powder to keep skin dry, fresh, and chafe-free.
17. Cleaning and Dusting Agent
- Cornstarch can serve as a gentle and effective dry cleaning agent for books, papers, fabrics, and more.

Frequently Asked Questions (FAQs) about Cornstarch Uses
Q: Can I use cornstarch instead of flour for all thickening needs?
A: Cornstarch works as a substitute for flour in most cases, and produces a clearer, glossier finish. However, it loses its thickening power if cooked for too long or at high temperatures, so add near the end of cooking.
Q: How do I store cornstarch?
A: Store cornstarch in a cool, dry place in a tightly sealed container. Kept away from moisture, it lasts indefinitely.
Q: Is cornstarch gluten-free?
A: Yes, pure cornstarch is naturally gluten-free. It’s a common ingredient in gluten-free recipes and suitable for people with celiac disease or gluten sensitivity.
Q: Can cornstarch cause skin irritation?
A: Cornstarch is generally safe for most skin types, but in rare cases it may irritate very sensitive skin or worsen certain yeast rashes. Avoid using it on broken skin or existing infections.
Q: Is it safe to use cornstarch-based powders on babies?
A: Many parents prefer cornstarch powder as a natural alternative to talcum powder for preventing diaper rash. It’s generally safe when applied to clean, dry skin, but be careful to avoid creating airborne dust that could be inhaled.
Handy Tips for Using Cornstarch
- Always create a smooth slurry by mixing cornstarch with cold liquid before adding to hot sauces or soups to prevent lumps.
- For crispy crusts, coat meat or vegetables in cornstarch just before frying.
- Cornstarch is flavorless, so it won’t alter the taste of your dishes—just the texture.
- Remember that cornstarch-based sauces thicken as they cool; if your sauce seems thin when hot, let it rest before adding more.
- To make Oobleck or similar slime, discard in the trash, not down the sink, to avoid clogging drains.
