In a small bowl, whisk together the peanut butter, lime juice, tamari, sriracha, and maple syrup. Whisk in water, 1 tablespoon at a time, to reach a drizzleable consistency. Peanut butters vary in thickness, so you may need more or less water each time you make this recipe.
If desired, stir in garlic, ginger, sesame oil, and/or more sriracha.
