We nearly always eat home baked bread.
You don't need to use fresh yeast, dried is perfectly good, and most supermarkets stock decent flour such as Allinson's. We have the Paul Hollywood book, and another good one is the Women's Institute by Liz Herbert. The loaves are great. We occasionally buy a loaf from a baker, but the only sliced one that seems reliable is, as others have said, Warburtons.
