Sourdough Flaxseed Rye Bread – Leinsamenbrot

sourdough-flaxseed-bread-recipe-a

Each movement of the serrated knife shoots sesame seeds in all directions, but it’s a minor annoyance that is easily justified. Baking releases the fragrance of the sesame seeds onto the crust and makes a noticeable difference. I should’ve done the same thing with the second loaf.

Inside, the flaxseed aroma is more subtle but thoroughly permeates the sour boule. Lightly toasting a slice wakes up the flaxseeds in the same way your oven does the sesame seeds on the outside.

I used dark rye flour instead of medium rye so these came out denser and more deeply browned than intended in the original recipe. I’ll stick with the dark rye when (not if) I make another batch.
