In a small mixing bowl, combine peanut butter, soy sauce, ginger powder, garlic, chili flakes, and lime juice.
Mix in water one tbsp at a time until the sauce reaches your desired consistency.
Transfer sauce to an airtight container in the fridge and let sit for at least 10 minutes - the flavors combine so well if you let it sit! Refrigerate leftovers for up to 10 days.
Add more or fewer chili flakes to reach your desired spicy level. I found 2 tsp was plenty spicy!
You can sub lime juice for lemon juice or even apple cider vinegar.
The longer you let the sauce sit after being mixed, the better the flavor becomes. Make sure to let the sauce sit before tweaking the ingredients too much, I find it becomes sweeter after resting.
This peanut sauce is perfect in our Spicy Peanut Chickpeas recipe!
