Step 1

Add chili flakes, garlic, vinegar, honey, 3/4 c. water, and salt to a small saucepan and bring to a boil over med-high heat. Boil for a minute at medium heat, stirring constantly.

Step 2

Mix the potato starch with the remaining water and add to the sauce, stirring over medium heat until thickened - about another minute or two.

Step 3

Remove from heat, cool thoroughly and transfer to a container to store in the fridge (the sauce keeps for a couple of weeks, if it lasts that long...). Reused glass dressing bottles or canning jars both work well.
