The answer to this common question is both yes and no. While potato flour and cornflour share some similarities, they differ in their properties, making them suitable for different applications. Let’s explore their unique characteristics and how to use them effectively.

Understanding Potato Flour

Potato flour is a fine powder made from dehydrated potatoes. It is naturally gluten-free and has a slightly earthy flavor. Potato flour is primarily used as a thickener and binder in various dishes, such as soups, sauces, and baked goods.

Pros:

• Gluten-free
• Good thickening agent
• Adds a subtle earthy flavor

Cons:

• Can have a slightly bitter aftertaste if overused

Understanding Cornflour

Cornflour, also known as cornstarch, is a white powder made from the endosperm of corn kernels. It is naturally gluten-free and has a neutral flavor. Cornflour is primarily used as a thickener in soups, sauces, and gravies.

Pros:

• Gluten-free
• Excellent thickening agent
• Neutral flavor

Cons:

• May not provide as much binding power as other flours
• Can be susceptible to clumping

Substitutions: When to Use Potato Flour Instead of Cornflour

While potato flour cannot fully replace cornflour in all applications, it can be an effective substitute in certain cases:

• Soups and Sauces: Potato flour can be used as a thickener in soups and sauces. It will add a slightly earthy flavor, which may be desirable in some recipes.
