Here's a simple little bakery, on an off-street, not very busy. Walk in, buy a plain old cheese sandwich for €1.50. Nothing much: just a lovely little baguette, baked a few minutes ago, with lots of lovely brie.
It's not that hard. Flour, water, yeast, cheese. It's exactly what I get at the pizza shop twice a week. But simpler (no sauce), and infinitely better. Why can't we do this?
