Flavoring homemade yogurt
What are the best ways to flavor homemade yogurt? I like it to be sweet and fruity, but not as sweet as the commercial brands - too much for me! But I do like the idea of the entire yogurt being flavored by fruit purees instead of just fruit pieces in it. Should I use fruit jams? Jellies? Syrups? Or should I just puree fresh or frozen fruit and sweeten it another way? If so, what's the best way to sweeten that doe NOT involve honey? How should I add vanilla if that's the flavor I want? Thanks!
