Key Facts

Cornstarch is a pure starch derived from the corn kernel, making it a powerful thickening agent.

Baking soda is an alkaline compound (sodium bicarbonate) that reacts with acids to produce carbon dioxide, causing baked goods to rise.

Substituting baking soda for cornstarch can result in a soapy or metallic taste and may not provide the desired thickening effect.

Accidentally using baking soda instead of cornstarch in a dish can often be salvaged by adding an acid to neutralize the baking soda.

According to a study by the American Chemical Society, cornstarch’s ability to thicken is due to its amylose content, which forms a gel when heated with water.

Can I use baking soda instead of cornstarch?

Baking soda cannot be used as a substitute for cornstarch. While both ingredients are white powders and may look similar, they have distinctly different functions in cooking and baking. If you use baking soda instead of cornstarch, you will not achieve the desired thickening effect, and you may end up with an undesirable taste or texture in your dish.

Cornstarch is a pure starch derived from the endosperm of the corn kernel. It is a powerful thickening agent that forms a gel when heated with liquid. This ability makes it ideal for thickening sauces, gravies, soups, stews, and pie fillings. Cornstarch also creates a smooth and glossy finish, enhancing the visual appeal of dishes.

Baking soda, on the other hand, is a chemical leavening agent composed of sodium bicarbonate. It is used in baking to make doughs and batters rise. When baking soda comes into contact with an acidic ingredient, such as vinegar, buttermilk, or lemon juice, it produces carbon dioxide gas. These gas bubbles get trapped in the batter, causing it to expand and become light and airy.

Why Baking Soda Is Not a Suitable Substitute for Cornstarch

Baking soda is an alkaline compound, meaning it has a high pH. When added to a dish as a thickener, it can impart a soapy or metallic taste, especially if the dish does not contain enough acidic ingredients to neutralize it. Additionally, baking soda does not have the same thickening power as cornstarch. It may cause some initial bubbling or foaming, but it will not create the desired gel-like consistency needed to thicken sauces or gravies effectively.

What Happens If You Accidentally Use Baking Soda Instead of Cornstarch?

If you accidentally use baking soda instead of cornstarch, don’t panic. Depending on the amount used and the type of dish, you may be able to salvage it. One approach is to add an acidic ingredient, such as lemon juice, vinegar, or cream of tartar, to neutralize the baking soda. This can help mitigate the soapy taste and prevent further reactions. However, adding acid may not restore the desired thickness, and it may alter the flavor profile of the dish.

Another option is to dilute the dish by adding more liquid or other ingredients. This can help reduce the concentration of baking soda and minimize its impact on taste and texture. However, this approach may also result in a thinner consistency than intended.

What Can I Use Instead of Cornstarch?

If you find yourself out of cornstarch, several suitable alternatives can provide similar thickening properties. The best substitute will depend on the specific recipe and desired outcome.

Arrowroot Powder

Arrowroot powder is a starch derived from the roots of the arrowroot plant. It is a powerful thickener that creates a glossy finish similar to cornstarch. Arrowroot powder is also gluten-free and has a neutral flavor, making it a versatile choice for various dishes. When substituting arrowroot for cornstarch, use an equal amount.

Tapioca Starch

Tapioca starch, also known as tapioca flour, is extracted from the cassava root. It is another excellent gluten-free option that provides a glossy, slightly chewy texture. Tapioca starch works well in pie fillings and fruit desserts. When substituting tapioca starch for cornstarch, use about twice the amount.

Rice Flour

Rice flour is made from finely ground rice. It is a common ingredient in gluten-free baking and can also be used as a thickener. Rice flour creates a smooth, creamy texture, but it may require slightly more liquid to achieve the desired consistency. When substituting rice flour for cornstarch, use about twice the amount.

All-Purpose Flour

All-purpose flour can be used as a thickener in a pinch, but it has a lower thickening power than cornstarch. It also contains gluten, so it is not suitable for gluten-free recipes. When substituting all-purpose flour for cornstarch, use about twice the amount. Additionally, be sure to cook the flour thoroughly to eliminate any raw flour taste.

Cornstarch vs. Baking Powder: Understanding the Difference

Cornstarch and baking powder are not the same, and they cannot be used interchangeably. Cornstarch is a pure starch used as a thickening agent, while baking powder is a leavening agent used to make baked goods rise. Baking powder is a mixture of baking soda, an acid (such as cream of tartar), and a moisture-absorbing agent (often cornstarch).

Can I Make Baking Powder from Cornstarch?

While cornstarch is a component of some baking powder formulations, it cannot be used alone to make baking powder. Baking powder requires both an alkaline component (baking soda) and an acidic component (such as cream of tartar) to create the leavening reaction. However, you can make a homemade baking powder substitute by combining cornstarch, baking soda, and cream of tartar in the correct proportions.

What Are the Best Practices for Using Cornstarch?

To achieve the best results when using cornstarch as a thickener, follow these guidelines:

Create a Slurry: Always mix cornstarch with a cold liquid before adding it to a hot mixture. This helps prevent clumping and ensures a smooth consistency.
Gradual Addition: Add the cornstarch slurry to the hot liquid gradually, while whisking constantly, to prevent lumps from forming.
Cook Thoroughly: Cook the mixture over medium heat, stirring constantly, until it comes to a boil and thickens to the desired consistency. Cornstarch needs to be heated to around 203°F (95°C) to fully activate its thickening properties.
Avoid Overcooking: Overcooking cornstarch can cause it to break down and lose its thickening power. Once the mixture has thickened, remove it from the heat.

When to Use Cornstarch vs. Baking Soda in Recipes
