The best brand of dried soy curls to use are from
Butler Foods. They're available in select places in Canada and the U.S. and can be ordered online as well. Use 1 whole bag of those, or you can find dried TVP pieces in most health food stores. 4 cups is approximately a standard size bag of pieces. You'll have enough sauce for this amount. Soak the soy pieces in a large bowl with the water, apple cider vinegar, lemon, and cayenne mixture for 1 hour in the fridge. Meanwhile, make your bbq sauce.
