Making cornstarch chunks is a relatively straightforward process. The most important thing to keep in mind is that cornstarch is heat sensitive and can become gummy if cooked for too long or at too high of a temperature.
The first step is to gather the ingredients you’ll need. You will need cornstarch, vegetable oil, and water. You’ll also need a medium-sized saucepan.
In a medium-sized saucepan, mix together one cup of cornstarch and one cup of cold water. Stir this mixture until it is smooth.
Once the mixture is smooth, heat the pan over medium-high heat. As the mixture heats, it will thicken. Once it has thickened to a pudding-like consistency, add two tablespoons of vegetable oil and stir.
Continue to stir the mixture until it is thick and lumpy. Once the mixture has reached the desired consistency, turn off the heat and remove the pan from the stove.
Allow the pan to cool for at least 10 minutes. Once the mixture has cooled, you can use a spoon to create small chunks. You can also use a spatula to scrape the mixture from the sides of the pan and form it into larger chunks.
Once your chunks are the right size, place them on a plate lined with parchment paper. Allow the chunks to cool completely before serving or storing. Enjoy!
