The jar

Sourdough, kept simply.

A starter is a small daily obedience: flour, water, and time. This section is the jar, the feedings, and the bakes that come from them, including the discard you should not feel guilty about.

How to feed the jar

Ready when it has doubled, not when you are impatient.

01

Begin

Day one is only flour and water, equal weights, in a clean jar. For the next week, keep a small amount and feed it the same weights of flour and water each day. You are not behind if nothing exciting happens before day four.

02

Know it is ready

Bake with it when a feeding reliably doubles the jar in 4 to 8 hours, the surface is domed and bubbly, and the smell is clean and tangy. A fallen starter can still flavor pancakes. It will not lift a country loaf.

03

Keep it

In the refrigerator, a weekly feeding is enough. The day before bread, feed it and leave it out until it peaks. Use what the recipe asks, feed the jar again, and put it back once it is lively.

04

Use the extra

The portion you do not put back in the jar is discard. Once it smells pleasant, it becomes pancakes and crackers. The first murky days of a brand-new starter belong in the compost, not in breakfast.

“See how the farmer waits for the precious fruit of the earth and is patient with it.”

James 5:7

Every recipe uses a scale. Cups will fight you here.
