After searching high and low for these ingredients, I finally made them today. I love how these came out after 3 and half hours later. It is a bit too long to bake them.
So glad the meringue worked out for you natylka! I know, they take forever to bake, thanks to the xanthan gum holding onto water for so long. I'll definitely update the recipe if I ever find a way around this. Thanks for your input!
