In a mixing cup, combine hoisin sauce, peanut butter, white wine vinegar, sriracha, and garlic.
Thin the sauce with water 1 tablespoon a time while stirring until your desired consistency.
Garnish with chopped peanuts on top.
The sauce will thicken the longer it sits. Thin with more water as necessary.
Usage: Use it as a dipping sauce for Vietnamese fresh summer rolls, spring rolls, Chinese egg rolls, and more!
Storage: the sauce stores well in an airtight jar in the fridge. It should last 1 week with no double dipping.
Notes
Hoisin Sauce: Don't skip the hoisin sauce! It adds a savory umami flavor that perfectly balances the sweet, nutty peanut butter.
Balancing the Flavors: For the best flavor, use a 1:1 ratio of hoisin sauce to peanut butter, or a 1.5:1 ratio if you prefer a little more hoisin kick.
Consistency is Key: The sauce will thicken as it sits. If it gets too thick, just thin it out with a bit more water until it's just right.
