Molasses comes from sugar cane or sugar beets and is a byproduct of making either refined or raw sugar. It has a distinctive flavor and is super-rich in minerals and vitamins. You can find unsulfured molasses in any grocery store, but it's not as common as other types of molasses. Some others are treated with sulfur dioxide (SO2) to preserve color and act as antioxidants. SO2 maintains color but may also cause allergic reactions in sensitive individuals. Once off-gassed, it can also create an unpleasant smell and taste. In conclusion, look for unsulfured molasses on labels if you're trying to avoid added SO2 during processing. Knowing more about uncultured molasses will help you choose substitutes for molasses.
