Piloncillo is widely available in the US. I cannot speak for other countries (other than Latin countries which are sure to have it). As I mentioned in the post, the flavor is unique, but you can substitute brown sugar with a bit of molasses. Find piloncillo on Amazon.
Cooking time will vary depending on the thicknesses of your wedges. It should require 30-40 minutes.
Macronutrients (an approximation from MyFitnessPal.com) are based on 1 cup of raw pumpkin, and 1/4th of the syrup (that is pretty generous!). I also included 2 ounces of full fat vanilla yogurt with each serving.
