Toss the water, chopped bell pepper, onion, chilies, and garlic into a blender or food processor. Give it a few pulses. You still want little bits, not a runny puree.

Scrape that chunky mix into a saucepan. Sprinkle in the salt and sugar, pour in the vinegar. Stir it all up, set it over medium heat, and let it cook until you can't see any sugar grains left.

Mix the cornstarch or potato starch with 2 tablespoons water. Slowly add it into your bubbling sauce, keep stirring the whole time. Let it gently cook until it thickens up just a bit.

Use as a dipping sauce with fried stuff, grilled meats, or roasted veggies. Or just slap it on as a tasty topping whenever you want.
