To activate your sourdough starter, follow these simple steps:

1. Begin by adding 1 tablespoon of all-purpose flour and 1 tablespoon of room temperature water to into your pint-sized glass jar. Stir the mixture thoroughly with wooden stir-stick. 
2. Cover the jar with your included, breathable material and secure with the screw-top lid or a rubber band. Store it in a warm place like a countertop for 12-24 hours.
3. After this initial period, feed the starter with an additional 2 tablespoons of flour and 2 tablespoons of water, stirring thoroughly. The consistency should resemble pancake batter.
4. After 12-24 hours, feed the starter with an additional 1/4 cup of flour and 1/4 cup of water. Stir thoroughly. 
5. After 12-24 hours, discard down to 1/4 cup starter and then feed the starter with 1/4 cup flour and 1/4 cup water. Stir thoroughly.
