I used british bread flour, Asda own brand which is just repacked Allinson's. Made for a very nice pizza in the end.
Is it? The one in the green bag? I use it for making sandwich loaves in a 4kg pullman tin, tear-and-share buns and fruit loaves in 2kg tins (Mary Berry's Hot Cross Buns recipe - but with extra spices - she's a bit mean with hers). It's a very good flour and at a very good price.
