Notes: I had success replacing the unbleached flour with white spelt flour — but I'm afraid other whole grain flours may be too heavy (resulting in dense / chewier cinnamon rolls). (ohladycakes.com)
I use white spelt flour for a lot of my recipes (gluten free but not wheat free if you have Celiac Disease or other wheat allergies). (delightfulmomfood.com)
The night before preparing the walnut swirl bread, mix 50 g of white spelt flour, 50 g of water and 1 tablespoon of your active sourdough starter. (mydailysourdoughbread.com)
