Combine 100g rye flour and 100g water in a clean container, cover, let sit out 24 hours at room temperature
Day 2:
In a clean container combine 100g rye flour, 100g water, and 100g yesterday’s starter. Throw out the remaining starter. Cover and let sit out at room temperature 24 hours. You should start seeing bubbles and some activity.
Day 3:
Repeat Day 2. Your starter should just about double or more!
Day 4:
Combine 100g all-purpose flour, 100g water, and 100g yesterday’s starter. Throw out the remaining starter. Cover and let sit out at room temperature 24 hours. The starter will definitely double and have larger air pockets.
Day 5:
Repeat Day 4. Mine had tripled by this point. You can totally use her to leaven bread!
Day 6 & 7:
Repeat Day 4.
Feeding your starter for the long term: You want a controlled growth of your starter when you are going to use it for bread. This is all in the feeding. Once you have an active starter you can switch to the following ratio for a stiff levain:
100g water
10g previous day’s starter
100g AP flour
Or this one for a Liquid Levain:
125g Water
10 g Previous day’s starter
100g AP Flour
