I use KAL powdered stevia and have for years, just because I have some issues w/ low blood sugar and it’s a nice way to sweeten plain yogurt w/o the sugar highs and lows. Anyway, not all stevia is created equal taste-wise. I like the KAL because it doesn’t have that bizzaro grassy aftertaste that some stevias have. A stevia tip: a little goes a LONG way, and using slightly too little is FAR better than using slightly too much. If you use too much stevia in something it just tastes plain weird.
Hope it helps!
