2lb Large tinned and 1lb tinned Rye Sourdough Loaf made with Shipton Mill Rye wholemeal Bread Flour. Rye breads tend to be heavier than wheat breads because the rye contains much less of the gluten/gliadin proteins which enable the light structure of a wheat bread. Nevertheless, such “heavy”-seeming rye breads are very light on the digestion and are even “digestive”…easy to assimilate, and almost therapeutic. Rye is often considered “European” and associated with dark German or Scandinavian breads, yet history shows that Rye was once widely eaten in the UK, especially in the North East.
