I've been wanting to try stevia for awhile, so when I was in the health food store yesterday, I asked the clerk and she directed me to a canister with a "Stevia" label on it. It was an olive green powder, which was not what I was expecting, but since I had never seen it before, I figured, that must be it! I bought a half-ounce to try it. When I got home, I made a pot of herbal tea and put a 1/4 tsp of the the stuff in it and stirred. Nothing happened! It did not dissolve. It just floated to the bottom and stayed there. When I tasted the tea, it was bitter, not sweet at all. So I think I may have bought the wrong thing. What does Stevia look like? Shouldn't it have dissolved? Does anyone know what I actually bought?
