This is the creamy peanut sauce that goes with fresh spring rolls: peanut butter loosened with warm water, deepened with hoisin, brightened with lime. The target is thick-but-pourable — heavy-cream-like, coating the back of a spoon — and the recipe gets you there by adding the water one tablespoon at a time.
Ingredients
Makes about 1 cup.
- 1/2 cup creamy peanut butter (conventional creamy gives the smoothest, most predictable result)
- 2 tbsp hoisin sauce
- 1 tbsp lime juice, plus more to taste
- 1 tsp sugar (optional; some peanut butters are already sweet)
- 1 clove garlic, finely minced or grated
- 1/2 tsp chili garlic sauce or sliced Thai chile (optional, to taste)
- 6 tbsp warm water, added gradually
- 2 tbsp crushed roasted peanuts, for topping
Method
- Whisk the peanut butter, hoisin, lime juice, sugar (if using), garlic, and chili sauce in a bowl.
- Add warm water 1 tablespoon at a time, whisking until smooth after each addition. The sauce will seize and look lumpy at first — keep whisking, it smooths out. Stop when it reaches a thick-but-pourable, heavy-cream-like consistency that coats the back of a spoon.
- Taste and adjust: more lime for brightness, more hoisin for savory depth, more chile for heat. If it thickens as it sits (it will), whisk in warm water a teaspoon at a time to loosen.
- Transfer to a serving bowl and top with crushed peanuts. Serve at room temperature.
Tips and ingredient notes
- Peanut butter: conventional creamy gives the smoothest result. Natural peanut butter works but separates more and needs extra whisking.
- Hoisin: adds the savory-sweet backbone. Check the label for gluten if that matters to you — hoisin commonly contains wheat.
- Consistency: the sauce should coat a spoon, not run off it. Natural vs. conventional peanut butter absorbs water differently — adjust the last spoonfuls by feel, using the heavy-cream benchmark.
Storage and food safety
Allergen note — important: this sauce is unsafe for peanut-allergic readers, full stop. It also contains soy (hoisin, peanut butter may contain it); check labels for gluten in hoisin. Refrigerate leftovers and use within 1 week. Stir and loosen with warm water before re-serving.
