Step 1

Whisk all of the ingredients except the cornstarch together in a small pot. You can blend them in a food processor or blender if you'd like.

Step 2

Bring the pot to a boil, then reduce the heat and simmer for 3 minutes.

Step 3

If you'd like to thicken it, dissolve 1 tablespoon cornstarch in 2 tablespoons of water until well mixed. Stir it into the szechuan sauce and stir until it thickens up, 2-3 minutes. For thicker szechuan sauce, use 2 tablespoons cornstarch.

Step 4

Cool and serve.
