you can also buy the lindt 85% dark chocolate in most supermarkets, which only has 19g of carbs per 100g, and no sugar alcohols at all, which means no stomach problems. It's very bitter, but some people like that, and since it's such a high percentage of cocoa, it's very low carb. When I use it to make chocolate mousse, I add splenda (which i bring in from england, but it could be there are other sweeteners here that could be used) to make it a bit sweeter.

this week for shabbat my sister dipped strawberries in melted sugarless chocolate - they were very good, but they did give us gas!
