this is my own creation, which i am posting here mostly for my own reference so i can remember this next time i want to make it, and also so others can enjoy it...
1.5 c. coconut milk
1.5 c. natural peanut butter (i.e., no sugar added)
2 T. soy sauce or Bragg's liquid aminos
1 T. brown sugar
1 T. rice vinegar
1-2 T. diced chilis (e.g., thai chilis, jalapenos, serranos)
1-2 T. sriracha (or other garlic chili sauce) - optional
water or extra coconut milk (as needed)
combine all ingredients except water/extra coconut milk in a small sauecpan. cook over a low flame until heated through. once hot, add water/extra coconut milk to achieve desired consistency. cook a minute or two longer - do not cook longer than this or the sauce will begin to solidify.
this is a good dipping sauce for lightly fried tofu, or can be used to make peanut noodles.
