In a small blender or food processor, add soy miso paste, maple syrup, cayenne pepper, tamari sauce, and garlic powder. Blend together until smooth, adding water to thin into a paste.
Taste and adjust flavour as needed. Add more cayenne pepper or chili flakes for spice, tamari sauce for depth of flavour, maple syrup for sweetness, garlic for “zing” or salt for saltiness.
Store in the refrigerator up to 2 weeks or in the freezer up to 1 month.
