While still at the seed culture stage I'm reading Reinhart's book ahead to the mother starter stage and I admit to feeling confused. His instructions to convert from seed culture to mother stage are clear; it's the instructions for refreshing that confuse me.
He states: "Whenever the mother starter gets low, rebuild it using 4 oz of the old starter and repeating the instructions above". (ie combining 4 oz of Phase 4 seed culture with 9 oz spring water and 12 o whole wheat flour.)
But then in his following paragraph he states: "To rebuild your mother starter, use 1 ounze of mother starter and add 3 ounces of flour and 2 gto 2.25 ounces of water".
So is it 4 oz or 1 oz of old mother starter?
I want to keep my mother starter indefinitely in the refrigerator. How do I feed it? And do I feed it once a week as I've read in various places, or every 5 days?
Any advice would be very much appreciated, thank you!
