Another big pan de mie sandwich loaf. Sourdough, but also with some super ripe kefir added. A mix of KA bread flour, Glick's high gluten and some white rye. Dough was from Saturday, baked last night. Didn't get a high as the last loaf but plenty of real estate for sandwich or toast. My tangiest sourdough yet. Also, the $2 1960's electric knife from the local garage sale is my new favorite bread knife.
edit: There was maybe 1/4 cup of potato flakes added too. I forgot.
