Combine all the ingredients and dissolve the sugar completely. This works easily with stevia instead of the sugar. I use 2-4 drops.
Keeps in the refrigerator for up to 3 days. Store in tightly sealed glass container in the fridge.
Vietnamese Peanut Sauce:
Using a food processor or mortar, pound peanuts to a course powder. Set aside.
Sieve the tamarind and water. Set aside the liquid, discard the solids.
Heat the oil in a wok or skillet over high heat. Add garlic and stir fry about 15 seconds, until color begins to change. Toss in the pork and cook until it is cooked through.
Add soybean paste and tamarind and stir until blended. Add 1/2 cup of water. Then stir in most of the ground peanuts (reserve 1 T for garnish). Add the sguar and chiles. Add water until you reach the desired texture (thick and pourable, but not watery).
Serve at room temperature or warmer. Squeeze a lime over it and add the reserved peanuts.
This keeps in the refrigerator for 3 days or freezes for one month. Reheat before serving.
