Step 1

Combine cornstarch and water in a mason jar until smooth. Then add in all the remaining ingredients. Fasten the lid, and shake until fully incorporated.

Step 2

(Alternatively, you can mix everything in a bowl with a whisk.)

Step 3

Use as desired. Instructions for a basic stir fry are in the full article.

Step 4

If not using right away, store in a sealed jar or airtight container in the refrigerator. Note: after it's been sitting and untouched for a while, the ingredients will separate and the cornstarch has a tendency to settle and harden at the bottom of the jar. Take a dull knife to loosen it up, then fasten the lid and give it a good shake to reincorporate everything before using.
