Three cities. Three specialist cook shops. No luck.
I thought I may find a banneton or proving basket somewhere in Leeds, Manchester or Sheffield. The cook shops were full of lovely shiny things but when I enquired about proving baskets I got blank looks. When I explained what they were for, the Leeds shop assistant exclaimed that though they were not afraid of a niche market, this product was still too specialised for them. So much for the great real bread revival.
