Don't be fooled by rustic looking "artisan" sourdough bread in supermarkets! There's no law or food legislation on what constitutes artisan sourdough bread so supermarkets add extra ingredients to speed up the process. It takes up to 2 days to make a real sourdough loaf using just 3 ingredients; water, flour and salt. This process gives it flavour. Typical factory made or "baked in store" sourdough ingredients; Wheat Flour (Wheat Flour, Calcium Carbonate, Iron, Niacin, Thiamin), Water, Rice Flour, Salt, Wheat Flour, Rapeseed Oil, Flour Treatment Agent (Ascorbic Acid) Real sourdough bread is available from Haddington Food Assembly; the online farmers' market Supermarket taste test - https://www.theguardian.com/lifeandst... What is the food assembly? It's like a farmers' market; fresh local produce direct from the producer, except you order online or with the App then collect from the producers at the venue.
