To mix powdered starch effectively, you need to create a slurry with cold water first to prevent clumping when it's introduced to hot water. Here's how:
-
Combine starch and cold water: In a bowl or jug, add four tablespoons of powdered starch to a small amount (approximately 1/4 cup) of cold water.
-
Stir until smooth: Thoroughly mix the starch and cold water until you achieve a smooth, milk-like consistency, ensuring there are no lumps. This is crucial for even distribution.
-
Introduce to hot water: Slowly pour the smooth starch mixture into one pint (2 cups) of hot water, stirring constantly.
-
Continue stirring while heating: Continue stirring the mixture over low heat until it thickens. Be careful not to boil it, as this can alter its properties.
-
Use or store: Once the starch mixture is smooth and thickened, it's ready for its intended use. If storing, allow it to cool completely and keep it refrigerated in an airtight container.
Why this method works:
-
Cold Water First: Mixing starch with cold water first creates a slurry, preventing the starch granules from clumping together when they come into contact with hot water. Starch granules gelatinize quickly in hot water and will clump if added directly.
-
Consistent Stirring: Stirring ensures even distribution of the starch granules, preventing lumps and resulting in a smooth, consistent mixture.
-
Slow Introduction to Heat: Slowly pouring the starch slurry into the hot water while stirring gives the starch granules time to hydrate and thicken evenly.
This method is commonly used for thickening sauces, gravies, desserts, and even for making homemade fabric stiffeners.
