I've had a few attempts at a sugar free pavlova. The problem the sugar helps create that hard outer shell and soft inner. When using dextrose it stays soft like meringue so you don't get that hard outer shell. After a bit of research I'm going to attempt again using something else. However in the mean time, some tips. If you cannot go cold turkey, why not try reducing your sugar intake slowly? I know your not supposed to make dextrose treats until after withdrawl, but you know what the dextrose treats actually helped me during my withdrawal period. My main problem was the sweet treat after dinner. During the day was fine, i was happy to have cheese, nuts, kabana etc but nothing would change that after dinner sweet. I would only have a tiny bit, enough to keep me satisfied. Eventually the cravings went and I stopped having dextrose treats altogether.
