75% is ok and tastes more like chocolate! Just 2 squares is about right and shouldn't cause too much of a spike. I'm eating some 85% right now, lol... slightly bitter but still tastes like chocolate. I did track down some 98% which bore no resemblance to chocolate as we know itSince becoming diabetic in October I have stayed away from chocolate and sweets. I am need chocolate!!! Can someone give me some advice on which chocolate to choose. I have read that 90% is ok. Many thanks.
