In a small blender or food processor, combine the chickpea miso, maple syrup, chili flakes, coconut aminos, and minced garlic. Blend until smooth, gradually adding water as needed to achieve a thick, spreadable paste.
Taste the mixture and adjust according to preference. Add extra chili flakes for more heat, coconut aminos for enhanced umami depth, maple syrup for a touch of sweetness, or garlic for a sharper bite. If additional saltiness is required, a pinch of salt can be incorporated.
Transfer to an airtight container and store in the refrigerator for up to two weeks. For extended use, freeze for up to one month. This flavorful sauce is perfect for drizzling over tempeh, tossing with crispy cauliflower wings, whisking into marinades, or blending into bold, spicy sauces.
