It's totally up to your preference, but I'm also in the process of doing the research to find out which sweetener is best. In the meantime, I’ll continue to occasionally use natural unprocessed sweeteners like maple syrup and raw honey, but in very small amounts, so I can keep the glycemic impact low. Also, my general rule of thumb for adding sweeteners is to not follow recipes at all. 1-2 cups of sugar in a batch of cookies is insane. A great keto beginners tip (for those not ready to jump in full-keto right away), is to add your sweetener till you can just taste a hint of sweet. Sweet should be an undertone to the awesome healthful flavors in our food like herbs, spices, healthy fats, etc. It should definitely not be the overpoweringly primary flavor we taste. If you have a different philosophy, please feel free to substitute the honey for your favorite keto sweetener! And if you feel like enlightening me with your own ideas on sweetness, make a comment at the end of this post.
