I thought this was so-so and plan to play around with it more but both the girls loved it and ate almost the lot with beetroot dip!
here's my VERY rough "recipe"
i used 500g plain GF flour (orgran brand). i added in around 2-3 tabs each of:
coconut flour, potato starch, lupin flour, tapioca starch and flaxmeal
about 1 tab coconut sugar, 1 tspn salt, 1-2 tabs plain yoghurt, yeast (around 1 sachet) and 1 egg.
i mixed it in my thermomix and just added enough warm water to get the dough i needed. i did 3 minutes on the knead setting
it a little til smooth and pressed out to shape. let it rise for 30
mins then topped with beaten egg, nigella and sesame seeds and baked at
200'c for 25 mins
