How to Make Corn Starch Slurry?
To make a corn starch slurry, start by adding cornstarch gradually to your sauce or soup.
It is important to add it gradually and not by itself.
If your sauce or soup becomes too thick, you can adjust the thickness by adding water.
It’s important to note that corn flour and cornstarch are not the same.
Corn flour is made from ground, dried corn, while cornstarch is made from the starchy part of a corn kernel.
Cornstarch is mainly used as a thickener and gives a smooth texture with a glossy luster.
If you prefer to use a substitute for cornstarch in Japanese or Asian recipes, you can try using potato starch, tapioca starch, or arrowroot.
Each substitute may have different ratios, with arrowroot being a one-to-one substitution with a glossy finish, potato starch also being a one-to-one substitution but having a tendency to clump more, and tapioca starch requiring 2 tablespoons for every 1 tablespoon of cornstarch.
Quick Tips and Facts:
1. Corn starch was first used as a substitute for wheat flour during World War II due to its low cost and widespread availability. It became a popular ingredient in various recipes and has remained a staple in many cuisines since then.
2. The process of making corn starch involves grinding corn kernels into a fine powder and then separating the starch from the rest of the components. This is achieved by soaking the ground corn in water and then allowing the heavier starch particles to settle while the lighter components are discarded.
3. Corn starch slurries were traditionally used in Chinese cuisine to thicken sauces and gravies. The addition of a corn starch slurry not only increases the viscosity of the sauce but also imparts a desirable glossy appearance, making the dish more visually appealing.
4. When mixed with water, corn starch undergoes a phenomenon known as “shear-thinning.” This means that the slurry becomes less viscous when subjected to force, such as stirring or whisking. As a result, corn starch slurries have a unique property of thickening when at rest but becoming more fluid when in motion.
5. Corn starch can be a handy household product for various non-culinary purposes. It can help remove grease stains from clothing by absorbing the oil, and can also be used as a dry shampoo substitute to absorb excess oils from hair.
Gradually Add Cornstarch To Sauce Or Soup
When using cornstarch as a thickening agent in your sauces or soups, it is important to add it gradually and never by itself.
To avoid clumps and uneven distribution, mix the cornstarch with a small amount of cold water before adding it to your sauce or soup.
This creates a slurry, which helps the cornstarch blend more easily.
Slowly pour the slurry into the sauce while continuously stirring to prevent lumps from forming.
Gradual addition allows the cornstarch to properly thicken the mixture, giving it a desirable consistency.
- Add cornstarch gradually
- Mix cornstarch with cold water before adding
- Create a slurry
- Slowly pour the slurry into sauce while stirring
- Gradually thicken the mixture
“When using cornstarch as a thickening agent in your sauces or soups, it is important to add it gradually and never by itself. Adding cornstarch directly into the mixture can result in clumps and uneven distribution. To create a smooth and even consistency, mix the cornstarch with a small amount of cold water before adding it to your sauce or soup. This creates a slurry, which helps the cornstarch blend more easily. Slowly pour the slurry into the sauce while continuously stirring to prevent lumps from forming. This gradual addition allows the cornstarch to properly thicken the mixture, giving it a desirable consistency.”
Adjusting Thickness With Water
Sometimes, a sauce or soup can become too thick after adding cornstarch. In such cases, water can be used to adjust the thickness. Adding small amounts of water at a time allows you to thin out the mixture to your desired consistency.
It is important to note that the amount of water needed may vary depending on the desired thickness and the amount of cornstarch used. Gradually add water while stirring continuously to incorporate it into the mixture evenly. This simple technique ensures that your sauce or soup reaches the perfect consistency and doesn’t become overly thick.
Corn Flour Vs. Cornstarch
It is crucial to understand the difference between corn flour and cornstarch when using them in your cooking. While both are derived from corn, they serve different purposes in the kitchen. Corn flour is made from grinding dried corn kernels, resulting in a flour-like consistency. On the other hand, cornstarch is extracted from the starchy part of the corn kernel.
Corn flour is typically used like other flours in baking and cooking, whereas cornstarch is primarily used as a thickener. Understanding this distinction will help you choose the right ingredient for your culinary needs, ensuring the success of your dishes.
Cornstarch For Smooth And Glossy Texture
When it comes to enhancing the texture of your sauces and soups, cornstarch is a preferred thickening agent. Unlike flour, which can make your sauce or soup cloudy, cornstarch offers a smooth texture with a glossy luster. The unique properties of cornstarch allow it to create a velvety texture that is visually pleasing. To achieve this, incorporate the cornstarch slurry into your mixture while it is being cooked, stirring continuously. This process ensures that the cornstarch is well-distributed and results in a silky smooth sauce or soup with a beautiful sheen.
Preventing Sauce From Becoming Looser When Served
It is common for the texture of a sauce to become looser when served, as the remaining moisture from the cooked ingredients continues to be released. To prevent this from happening, it is recommended to cook ingredients with higher moisture content for a longer duration before adding the cornstarch slurry. This extended cooking time allows the excess moisture to evaporate, leading to a thicker and more stable sauce. By following this technique, you can ensure that your sauce maintains its desired consistency, even after being served.

Substitutes For Cornstarch In Japanese/Asian Recipes
In Japanese and Asian recipes, cornstarch is often used as a thickener. However, if you don’t have cornstarch on hand or prefer alternatives, several substitutes can be used. Here are some alternatives for cornstarch in these recipes:
- Potato starch
- Tapioca starch
Arrowroot can be substituted in a one-to-one ratio with cornstarch while providing a glossy finish. Potato starch is also a one-to-one substitution, but it tends to clump more than arrowroot. Tapioca starch, on the other hand, requires using two tablespoons for every one tablespoon of cornstarch. These substitutes offer similar thickening properties and allow you to achieve the desired consistency in your Japanese and Asian dishes without compromising the taste or texture.
In conclusion, making a corn starch slurry is a simple yet essential technique for achieving the perfect thickness in your sauces and soups. By gradually adding cornstarch to your mixture, adjusting the thickness with water, and understanding the difference between corn flour and cornstarch, you can elevate the texture of your dishes.
Additionally, the use of cornstarch provides a smooth and glossy appearance, preventing your sauces from becoming looser when served. For those looking for alternatives, potato starch, tapioca starch, and arrowroot can be used as substitutes in Japanese and Asian recipes.
By following these guidelines, you can become a master of creating delicious and perfectly thickened sauces and soups in no time.
