Soft with uneven pores. Some bigger and some very fine. The pores are getting bigger towards the crust of the loaf.


This loaf has a hearty and aromatic taste. It is nice to taste the crunchy crust in combination with the soft and fluffy crumb.

Goes good with

Hearty things like ham, cheese or boiled eggs.
