In reply to Jacqui.

3 tsp = 1 tbsp, 16 tbsp = 1 cup. So if you use 16 packets, that should equal a cup of sugar in sweetness. Since erythritol is only 70% as sweet as sugar, you should use a bit more Truvia. Although we usually use a 1:1 conversion for simplicity's sake and to not make things overly sweet. We are trying to train ourselves off super sweet things :)
