What To Know
- It is made from a blend of hard and soft wheat, giving it a moderate protein content that makes it suitable for a wide range of baked goods.
- A starch that can be used for thickening and creating a glossy finish.

In the world of baking, all-purpose flour and cornstarch are two essential ingredients that play distinct roles. While they may seem similar in appearance, their composition and culinary applications are vastly different. Understanding the difference between all-purpose flour and cornstarch is crucial for successful baking.
All-Purpose Flour: A Versatile Workhorse
All-purpose flour is a staple ingredient in countless baking recipes. It is made from a blend of hard and soft wheat, giving it a moderate protein content that makes it suitable for a wide range of baked goods.
Composition and Properties
- Protein Content: 10-12%
- Starch Content: 65-75%
- Gluten Formation: Forms gluten when mixed with water, creating a chewy texture
- Uses: Breads, cakes, cookies, pastries, and more
Cornstarch: A Thickening Agent
Cornstarch, on the other hand, is a starch derived from corn kernels. Unlike all-purpose flour, it contains no protein and is used primarily as a thickening agent.
Composition and Properties
- Protein Content: 0%
- Starch Content: 99%
- Gluten Formation: No gluten formation
- Uses: Thickening sauces, gravies, soups, and more
Can I Substitute All-Purpose Flour for Cornstarch?
The answer is: No, you cannot directly substitute all-purpose flour for cornstarch in baking. The absence of protein in cornstarch means it will not form gluten, which is essential for giving baked goods their structure.
Can I Substitute Cornstarch for All-Purpose Flour?
The answer is: No, you cannot substitute cornstarch for all-purpose flour in baking. Cornstarch lacks the protein and gluten-forming ability required for creating baked goods with the desired texture and structure.
When to Use All-Purpose Flour vs. Cornstarch
- Use all-purpose flour: For baked goods that require gluten formation, such as breads, cakes, and pastries.
- Use cornstarch: For thickening sauces, gravies, soups, and other liquids.
How to Use All-Purpose Flour vs. Cornstarch
- All-purpose flour: Measure and add to dry ingredients according to the recipe.
- Cornstarch: Mix with a small amount of cold liquid before adding to hot liquids. This will prevent clumping.
Other Flour Substitutes for Cornstarch
If you do not have cornstarch on hand, you can use other flour substitutes:
- Arrowroot powder: A starch with similar thickening properties to cornstarch.
- Tapioca flour: A starch with a slightly chewy texture.
- Potato starch: A starch that can be used for thickening and creating a glossy finish.
Takeaways: Understanding the Difference
All-purpose flour and cornstarch are distinct ingredients with different roles in baking. Understanding their differences and using them appropriately is essential for successful baking outcomes. Remember, all-purpose flour is for structure and gluten formation, while cornstarch is for thickening liquids.
