it's heat stable so should be alright in cooking...wouldn't work in baking though I dont think cos of the diff in volume.

did yours come with a tiny scoop in the bottle/jar.....if so that is about the same as a teaspoon of sugar.....

just googled stevia recipes and got a heap of sites and blogs come up so maybe have a trawl through them...i personally haven't cooked with it more just used it in tea and on brekky type thing.
