I haven't been able to get bread flour for the past month and a half,
but I did manage to snag a 10 kilo sack of chapati flour, which I had
never used before. I made my first loaf with it today, using 250g whole
wheat flour and 300g of the chapati. It rose well, baked nicely, and
tastes good. The only difference was that it required 20g more water
than I usually use for this recipe (fits a 4x12 pan).
