How to Make a Cornstarch Slurry for Thickening
A cornstarch slurry is a mixture of cornstarch and water that is commonly used as a thickening agent in a variety of dishes, including sauces, soups, and stews. It is a simple and effective way to achieve the desired consistency and texture in your favorite recipes.
To create a cornstarch slurry, you only need two ingredients: cornstarch and water. The ratio of cornstarch to water in a slurry is typically equal parts, allowing for easy measurement and preparation. For example, you can mix 1 tablespoon of cornstarch with 1 ½ tablespoons of water to create a moderate amount of thickening. This ratio can be adjusted based on your preference and the specific dish you are preparing.
Once you have prepared the cornstarch slurry, the next step is to incorporate it into your dish. Start by heating the sauce, soup, or stew in a saucepan over medium heat. As the dish reaches a gentle simmer, slowly pour the cornstarch slurry into the pot while whisking continuously. This will help prevent clumping and ensure even distribution of the cornstarch.
Pro Tip: Adding the cornstarch slurry to a hot or boiling dish helps activate the thickening properties of the cornstarch. The heat breaks down the starch molecules, causing the mixture to thicken and create a smooth and velvety texture.
As you add the cornstarch slurry, you will notice the dish gradually thickening. Continue stirring or whisking the mixture until it reaches the desired consistency. Keep in mind that the slurry may require a few minutes to fully thicken, so be patient and keep stirring until you achieve the desired results.
If you find that your sauce, soup, or stew is not thick enough after incorporating the initial cornstarch slurry, you can make additional slurry using equal parts cornstarch and water. Mix the cornstarch and water in a separate bowl until smooth, then pour the slurry into the dish while stirring continuously. Repeat this process until you achieve the desired thickness. However, be cautious not to add too much cornstarch, as it can result in a sticky or overly thick texture.
The cornstarch in the slurry must be heated to around 203°F (95°C) to activate the thickening process. As the dish continues to cook, the starch molecules will absorb the liquid and thicken the sauce, soup, or stew. It’s important to cook the dish for a few minutes after adding the cornstarch slurry to ensure that the raw cornstarch flavor is cooked out and the mixture reaches its full thickening potential.
Using a cornstarch slurry as a thickening agent not only enhances the texture of your dishes but also allows you to adjust the consistency according to your preference. By mastering the art of creating a cornstarch slurry, you can confidently prepare a wide range of flavorful and perfectly thickened recipes.

Cornstarch Slurry Recipe:
- Mix equal parts cornstarch and water in a bowl.
- Stir until the cornstarch is fully dissolved and the mixture is smooth.
- Slowly pour the slurry into a heated sauce, soup, or stew.
- Stir continuously to prevent clumping and ensure even thickening.
- Cook the dish for a few minutes to activate the thickening properties of the cornstarch.
- Continue to stir until the dish reaches the desired consistency.
Alternative Homemade Glue with Cornstarch

Using Cornstarch as a Fabric Starch
When it comes to achieving a crisp and stiff finish for your fabric projects, cornstarch can be a fantastic alternative to commercial fabric starches. Not only is it effective, but it is also more eco-friendly and free from harsh chemicals. Here’s how you can use cornstarch as a natural fabric starch:
- Create a Cornstarch Paste: Start by mixing cornstarch and water in a bowl to create a paste. The consistency should be smooth and free from lumps. Use the following measurements as a starting point: 1 tablespoon of cornstarch to 1 cup of water.
- Dissolve the Mixture: Once you have prepared the cornstarch paste, dissolve it in a larger quantity of water. This can be done by adding the paste to a container filled with water and stirring until fully dissolved.
- Transfer to a Spray Bottle: To make application easier, pour the cornstarch mixture into a spray bottle. Make sure to shake the bottle well before each use to ensure that the cornstarch is evenly distributed.
- Apply to Fabric: Before ironing your fabric, spray a light and even layer of the cornstarch mixture onto the fabric surface. The cornstarch will help stiffen the fabric and create a crisp finish.
- Iron as Usual: After applying the cornstarch mixture, proceed to iron your fabric as usual. The heat from the iron will activate the cornstarch, helping to set the fabric and maintain its shape.
