One of my food memories from school was when one guy threw a slice of ”knäckebröd” (Swedish crisp bread) up in the air. The sandwich got stuck with its buttered side up on the ceiling, and I mean really stuck. No one seemed to pay any attention or tried to get the bread down. In fact it would have been a project by itself as the dining room was like a ball room with very high ceiling. Hm, I wonder if it still up there!

This recipe is by Alice at Brax on Food (freely translated by me).

twelve crisp breads
25 gram yeast (I used  ½  package of ¼ oz Active Dry Yeast)
1 tablespoon honey
200 ml (almost 1 cup) yogurt
400 ml (1 2/3 cup) water
600 ml (2 ½ cup) rye wholegrain flour
600 ml (2 ½ cup) wholewheat flour
1 tablespoon caraway seeds
2 teaspoons salt
and
100-200 ml ( ½ – 1 cup) regular flour for rolling the breads

Prepare the yeast depending on which yeast you are using. When the yeast is ready, blend it with honey, yogurt, water, rye and the wholewheat flour. Cover the bowl and keep at room temperature in a non-drafty area for at least 6 hours.
Roast the caraway seeds in a dry pan and crush them finely in a mortar. Blend in the salt and wholewheat flour. When the dough is ready, work in the wholewheat flour/caraway mixture. Add some of the regular flour to make a smooth dough. Divide the dough in 12 equal parts and roll them into balls. Preheat the oven to 225°C (435°F). Use a rolling pin and some regular flour to roll out every ball of dough into a thin round cake, approximately 1/8” (3 mm) thick. Place as many as you can fit on a baking tin and nibble the breads with a fork (or you can use a special rolling pin with small knobs). If you want to, you can make a hole in the middle with a small ”snaps” glass. Bake the breads immediately for about 8-10 minutes in the middle of the oven.  When finished let the breads cool down on an oven rack. Keep uneaten ”knäckebröd” in a sealed container. (Hanging on a broom stick will make them dusty).
