To a blender, add ½ cup peanut butter, ⅓ cup soy sauce, 3 - 4 tablespoons lime juice, 2 tablespoons brown sugar, 1 - 2 teaspoons sriracha sauce, 1 small clove garlic (grated), and 1 teaspoon ginger (grated).Note: You can also make peanut sauce by hand. In this case, add all ingredients to a small bowl and whisk until combined. The sauce won't be as smooth as the one made with a blender.
Blend until you reach your desired consistency and texture. Taste and adjust for lime juice and sugar.
