First day (evening)

1 dl (100 g) sourdough starter

3 dl (300 g) lukewarm water 

3 dl (180 g) bolted rye flour 

Mix together all the ingredients. Cover with a tea towel and leave to sit at room temperature (22–24° Celsius) until the next day.

Second day

3 dl (300 g) lukewarm water

2 tsp salt

2 tbsp honey

1 dl (0,4 cup US) fried onions, dried and crushed

10 dl (650 g) wheat flour

about 1 dl (60 g) bolted rye flour 

Blend all the ingredients with the starter dough and knead until the dough feels smooth. It takes 6–8 minutes. (Knead 6 minutes. If the dough still feels sticky, add bolted rye flour and continue the kneading process for couple of extra minutes.)

Cover and leave to rise at room temperature for 4 hours or until the dough has almost doubled in size. (The dough is ready for baking, if it slowly springs back, when you gently push a finger against the dough.)

Turn the dough out onto a lightly floured surface and knead it gently. Divide the dough into two equal pieces. Shape the pieces into two round loaves and put them into floured baskets. Cover and leave to rise at room temperature for 1,5–2 hours.

Put a baking tray into the oven and preheat it to 275°C. At the same time, put a sheet pan on the bottom rack to get it hot too. Using the parchment paper slide the breads into the hot baking tray and put them into the oven. When you do this, remember to throw ice cubes onto the heated sheet pan too. Reduce the temperature to 200°C and bake for 40–50 minutes. 

Let cool on a wire rack.
