Bring ½ c water to a boil and pour over peppers, allowing to them to re-hydrate for about 10 minutes.
Place the following in a blender: 1/2 cup boiling water, 1-2 Medjool dates (seeds removed), 1 clove garlic, 1 Tbsp apple cider vinegar, rehydrated chiles (skin only, remove all seeds & the stem; using seeds will add a LOT of heat)
Blend the above on high until smooth.
Then add the following: 6 oz tomato paste (no salt added), 1/4 tsp salt (or to taste), 1/4 tsp pumpkin pie spice
Continue blending until smooth, adding additional water if needed for desired consistency.
