These are hands down our favourite scrapers for sourdough. The curved edge is perfect for getting right along the inside of the bowl and the straight edge is great for cleaning up the counter or cutting rolls into shape.
Its made from plastic (only one of 2 pieces of plastic we sell in the whole shop!!) in Lincolnshire and it is uniquely flexible but strong and cleans up like a dream. We really haven't ever found a better bowl scraper and we have tried all of them!!
Size of this scraper 150mm x 75mm
