To make potato starch slurry, combine potato starch with warm water.
Here's a more detailed breakdown:
- Grate the potatoes: Scoop grated potatoes into a pot. You can use a food processor or a hand grater.
- Cover with water: Cover the grated potatoes with warm water. The amount of water you need will vary depending on the amount of potatoes you have, but approximately 3 to 4 cups (700 to 950 milliliters) should suffice.
- Stir and Separate: The process of grating and adding water helps to release the starch from the potato cells. The white substance you may see, especially after using a food processor, is the potato starch. This mixture of starch and water is the potato starch slurry.
