How do I thicken my soup with cornstarch?

To thicken your soup with cornstarch, first mix 1-2 teaspoons of cornstarch with an equal amount of cold water to make a slurry. Then, add the slurry to the soup and stir.

Does cornstarch thicken immediately?

Yes, cornstarch will thicken immediately when added to a hot liquid. However, it is important to note that the thickening effect of cornstarch will diminish with time, so it is best to add it just before serving. Additionally, it is important to make sure the cornstarch is completely dissolved before adding it to the liquid, as lumpy or partially dissolved cornstarch can cause a gritty texture.
