Fresh blueberries, cane sugar, apple cider vinegar, scorpion chilis, and our proprietary spice blend. On a scale of 1-5 (1 being mild, & 5 being extremely hot), this sauce is a 3. Our "Michigan Devil" hot sauce took some thought. It's packed full of fresh blueberry flavor, with a tangy vinegar undertone. This would go really well with fish and chips.
