I grow fresh stevia, then make it into a tincture which I cook down on low to produce non-alcoholic liquid stevia sweetener.
Experimented with things like vanilla, orange peel, lemon peel, Spearmint, peppermint.
Sometimes I'll include one or more of these in the tincture before I cook it down, but that can sometimes extract more bitter flavors. I've had some better results adding things right at the end of the process, then fishing them out. No bitter taste and there is still some of that flavor.
Makes a low calorie flavor with a nice sweetness.
If I'm looking for super sweet, I'll use honey.
