You can typically find Huy Fong Chili Garlic Sauce in the ethnic section at your grocery store.
It you like a thicker sauce, add in more cornstarch.
TIP! Wrap fresh ginger in plastic wrap and in a freezer bag and store in the freezer. Whenever a recipe calls for fresh ginger you have fresh ginger right at your fingertips. Plus keeping it in the freezer makes it easier to grate too!
