This is loosely based on Ken Forkish's levain from "Flour, Water, Salt, Yeast", but without the absurd flour quantities he requires. A starter is a microbial culture. Fifty grams of food might as well be a planet, as far as yeast is concerned.
- Whole wheat flour.
- All purpose flour or bread flour.
- A scale capable of gram measurements (I like this one).
- A small jar with a lid (mason jar, pimento jar, whatever).
- Tape you can write on (e.g. painters tape, masking tape).
- Patience.
