Whisk the base: In a medium bowl, whisk peanut butter with hot water until smooth and creamy. The hot water helps to emulsify everything.
Add the flavor boosters: Stir in sriracha (or Thai red curry paste), soy sauce, honey, rice vinegar (or lime juice), sesame oil, garlic, and ginger. Mix until well combined.
Adjust the texture: If the sauce feels too thick, add a splash of hot water. If it’s too thin, whisk in a little more peanut butter.
Balance the flavor: Taste the sauce. If it’s too salty, add a touch more honey. If it feels flat, brighten with more lime or vinegar. For extra spice, stir in more chili paste.
