Ingredients
Method
- Activate the yeast: pour 50 ml of warm water over 1 tsp of dry yeast and let it stand for 10-15 minutes.
- Sift the rye and wheat flour into a bowl, add the salt, the warm kefir and the remaining 100 ml of warm water.
- Pour in the activated yeast and knead the dough. Dust in a little extra flour only if needed: the dough should stay tacky, but not glue-like.
- Gather the dough into a ball, place it in a bowl greased with vegetable oil, cover with plastic wrap and leave for 40 minutes.
- Punch the dough down, knead it for about 3 more minutes, then cover again and let it rise for another 40 minutes.
- Punch down and knead once more, shape into a ball, place on a flour-dusted baking sheet, cover with plastic and proof for 1.5 hours.
- Mentally divide the loaf into 4 segments and score one of them. This is mandatory: carbon dioxide escapes through the cut, otherwise the loaf will tear badly.
- Preheat the oven to 200°C (390°F) with an empty tray on the bottom. Put the bread in, pour a cup of boiling water onto the tray and bake with steam for 5 minutes.
- Remove the tray and bake for another 20 minutes at 200-220°C (390-430°F). Cool the loaf on a rack before slicing. Enjoy!

Notes
Don't overload the dough with flour - it should stay slightly tacky. Steam at the start of baking gives the crackly crust; the score keeps the loaf from tearing.
