I cannot seem to see the MG post...xanthan is available here, as psyllium and all the new or alternative ingredients, or most of them....it is popular niche with many shops offering...I have never cooked with xanthan before, but possibly will.
i used erythrite, it was fine in the beginning, and at some point, i had to stop using it, as it bothers me digestively severely, so i stopped.
just on the sub front, in general.
i am aware that the sub version of the strudel will not be my dream one, i will do my dream one for kid and other family members, i just want to know the recipe and be able to make it. and the sub version will certainly not be equal in texture or flakiness...but hopefully edible.
