I'm based in the UK and one of our big supermarket chains is called Tesco... I always buy the best premium flour they have which is usually Allison's extra strength bread flour or Hovis Super Strength premium bread flour. These make an adequate loaf, which is tasty (as tasty as any in the shop!!) and has a good texture. I'm really just talking wholemeal bread flour and white bread flour.
Two days ago I broke my rule!!!!!!
