How to mix cornstarch and water?

In this brief article, we will provide you with the answer to the question: “how to mix cornstarch and water?”, discuss the applications of cornstarch and how to store it. 

How to mix cornstarch and water?

The cornstarch needs to be dissolved with warm water, without it getting too hot. The slower it is incorporated into the recipe, the better the end result.

Most mixtures will clump up as soon as we increase the heat a little, so it is best to stick to low heat and keep an eye on them during the process.

Cornstarch should never be added straight to a boiling liquid since it will clump and produce starch lumps. Cornstarch should be combined into a paste with room temperature or slightly chilly liquid before being incorporated into the hot liquid. This will ensure that the cornstarch molecules are distributed evenly before they expand and gelatinize.

What are the applications of cornstarch?


Cornstarch is most commonly used in food. Cornstarch can be added into cold or room temperature liquids and then heated to thicken them. Cornstarch is often regarded as a superior thickener to wheat flour since the resultant gel is transparent rather than opaque. 

Cornstarch is likewise flavorless when compared to flour and has almost double the thickening capacity. 

Cornstarch can also be used to cover fruit before baking in pies and other pastries. As it bakes, the thin coating of cornstarch combines with the fruit juices and thickens them. This keeps pies and other pastries from being too moist and the juices from running.  It is also used to thicken fruit juice when blended with it.

Cornstarch is also used to prevent caking. Shredded cheese is frequently covered with a thin layer of cornstarch to prevent it from clumping together and becoming a clump of cheese on the container. 

Cornstarch also absorbs moisture from condensation and avoids the formation of a slimy texture. To produce the same effect, a tiny quantity of cornstarch is frequently blended with powdered sugar. 

Cornstarch is a significant component in Chinese cuisine, notably in stir-fried meals. Cornstarch is used throughout the stir-frying process, beginning with the marinade and ending with the preparation of a sauce. Cornstarch, when combined with egg, is a key component in meat and fish marinades. 

When the cornstarch is pushed through the oil, it helps seal in the protein’s juices and makes it crisper. A cornstarch paste is added to the wok at the conclusion of the cooking process to thicken the liquids left at the bottom of the pan and so produce a sauce for the meal. The cornstarch ensures that all of the protein and veggies are evenly distributed.

Cornstarch-containing mixtures must be cooked before cooling. Cornstarch combinations that have been heated may allow moisture to drain or become thin again after chilling. After a little heating, the liquid may look thicker, but if the starch molecules are not fully gelatinized, they will lose moisture when chilled.


Cornstarch can be used to keep the skin healthy or to treat minor skin irritation. A paste formed with it and a little water cures sunburn, irritation from bug bites, and even diaper rash, which is common in newborns.

Those with oily skin may even add a little cornstarch to cosmetics like foundation, lipstick, or bronzing powder to reduce shine and give their makeup a more matte look. Another great application for it is talcum powder for your shoes and feet. After all, cornstarch aids in the retention of moisture and the prevention of undesirable smells.

For cleaning

Cornstarch, as unusual as it sounds, can be a useful cleaning tool, particularly for removing oil stains.

If oil has spilled over a tablecloth or a cherished garment, you can make a paste of the product and a little water and apply it to the afflicted region. Allow it to act for a few minutes after softly rubbing it. Then, using a moist towel, remove the mixture and wash as usual. 

How to store cornstarch?

Because cornstarch absorbs moisture, it must be stored in an airtight container that is not exposed to ambient humidity. Cornstarch should also be stored away from high temperatures. Cornstarch should be stored in a closed container in a cold, dry area. Cornstarch may be preserved forever if properly stored.
