When to Start Discarding Sourdough Starter?

When Can You Use Sourdough Discard? You can use the discard from your starter to bake, but it's better if you wait at least 7 days before you actually use it. In the first 5-7 days, it's better if you bin or compost your discard because the bacteria will be fighting it out and it will generally smell pretty gross.

Do you discard sourdough starter before or after feeding?

Feed the starter 1/2 cup (4 ounces, 113g) water and a scant 1 cup (4 ounces, 113g) all-purpose flour twice a day, discarding all but 1/2 cup (4 ounces, 113g) of the starter before each feeding. It should soon become healthy, bubbly, and active.

How do you dispose of a sourdough starter?

If you want to throw it away, it's best not to do so in its liquid state, as it can start to smell. Instead, pour it onto a piece of parchment or waxed paper and either bake it or let it air dry until it's brittle before throwing it away.
