I have been using xylitol sugar substitute for DIY toothpaste and mouthwash but have never used it for cooking mainly because I don't want to ingest anything made in China and also I don't eat a lot of food with high sugar content.
I came across this sugar substitute when I test baked several years ago for
Peter Reinhart's low carbs, gluten free, and sugar free book but never used it for cooking nor for my drinks. I recently got a large bag USA-produced xylitol made from
birch bark. The reviews are mixed, with a few users complaining of upset stomach. It's time to test for myself if it has an unpleasant flavor and if it will give me stomach cramps.
