Thai Spicy Peanut Sauce

This is an attempt to recreate the spicy peanut sauce served at my favorite Denver Thai restaurant.  Serve it with noodles, stir-fry, tofu, or spring rolls.   Use it as a dip.  Or, just eat it with a spoon.  This stuff is addictive.  You have been warned!

one 14-oz can organic coconut milk
1 cup organic peanut butter
4 tablespoons vegan sugar
2 tablespoons organic soy sauce
4 cloves garlic, minced
1 teaspoon chili paste
1/2 to 1 tablespoon rice vinegar (optional)
1 tablespoon cornstarch dissolved in 6 tablespoons water

Combine all ingredients in a saucepan.  Heat on medium high heat until bubbly.  Serve warm.
