Day 1: Mix 100 g flour (locally produced, organic) with 100 g of water in a bowl. Stir together. Let stand at room temperature. Cover with e.g. a lid.
Day 2: Let it rest.
Day 3: Add an additional 50 g of wheat flour and ½ dl (50 grams) of water. Mix well.
Day 4: Let rest.
Day 5: Add additional 100 g of wheat flour and 1 dl (100 g) water. Mix well.
Day 6: Sourdough is ready to use. This is the base. Can be stored in the refrigerator for about a week. "Feed" if necessary with equal parts (in grams results) water and wheat flour. Always save 50 g in the bottom of the bowl to use as the "concentrate" and feed when necessary. If it isn't feed often enough, it can "die". Is there too much in the bowl, you pour out a little but keep the "bottom".
