Hi Lynn, I think David is trying to get us off all sugar first then if we want to have sweet things use dextrose powder instead of white crystal sugar
Your grandchildren won't worry what sugar is in the cakes as long as it tastes nice and you will be doing them a favour particularly if they want to know about. If they change when they are young they will automatically look for alternatives when they grow up.
Dextrose is fine for everyone it's just a different type of sugar, the stuff our grand parents and great grand parents used before they big conglomorants fiddled with it
I have just had a go at making ice cream with dextrose and while I actually mucked up the making of it, not the recipe, it tasted quite good. Will be doing some modifications and it should end up being a hit with everyone.
Keep up the good work, we all need to take it easy and find what suits us best. hope this has been helpful
Cheers
Pam
