Raise your hand if you know lots about stevia. If you don't know anything, keep your hand down. Mine would be somewhere in the middle. Then the lovely people at NuNaturals sent me an email asking me to review some of their products. I figured this was as good a time as any to increase my stevia IQ. I knew that stevia was a great natural sweetener that I could cook with to avoid getting the gross sugar highs and energy crashes I experience when I eat sugar. But when I have cooked with stevia in the past I've struggled to get past the slightly bitter aftertaste.
