Tharg – Very funny. Arf! Arf!
Gothitjulie – I just looked for “bread flour” on the Waitrose website and all they have is Dove Farm gluten-free ‘White bread mix’ and g-f ‘Seeded bread mix’, which is a bit shocking. And only Marigold yeast flakes.
Sainsbury’s list own brand ‘Strong White’ bread flour plus Allison’s ‘Strong White’, ‘Very Strong White’, ‘Country Grain’ and ‘Wholemeal Plain’ flours, plus Dove Farm Organic Wholegrain Rye’ flour. NO YEAST!
Morrison’s only list Allinson’s ‘Very Strong White’ and Dove Farm ‘Buckwheat’ flour. Own brand ‘Yeast Flakes’ and Allinson’s ‘Dried Active Yeast’.
Asda list own brand ‘Strong White’, plus Allinson’s ‘Strong White’, ‘Very Strong White’, ‘Wholemeal’, ‘Brown’, ‘Seed and Grain’, and ‘Granary’. One brand yeast and Allinson’s ‘Easy Yeast’, ‘Dried Active’ and ‘Easy Bake’ sachets, and Marigold ‘Yeast Flakes’.
Tesco – own brand ‘Organic Strong’ and Allinson’s ‘Strong White’. Own brand ‘Fast Action’ yeast, Allinson’s ‘Time Saver’ and Marigold ‘Super Engevita’ yeast flakes.
I’ve no idea what your range of local supermarkets is, but as of today it looks like Asda might be your best bet!
