Process

Note, these instructions are written assuming the standard serving size, since you have modified the number of servings, these steps may need to be modified for best results
  1. Day 1: Combine 1 cup of flour and ¾ cup filtered water in a large clean mason jar. Mix together and cover with a thin dish towel or paper towel. Set aside in a dark warm place.
  2. Day 2-5: On each day, discard half of the starter and add ½ cup of flour and ⅓ cup filtered water to the jar. Repeat.
  3. Day 6 & 7: Discard half of the starter and feed with ⅓ cup flour and ¼ cup filtered water. You will do this twice a day on both days.
  4. Day 8: You are ready to bake!* 6-8 hours before you plan to use your starter, discard a portion of the starter and feed with ½ cup flour and ⅓ cup water. Once it has reached its peak in fermentation (you will see lots of bubbles), it will be ready to bake with!
  5. To maintain your starter, feed it a little bit each day, or keep it in the fridge to slow fermentation until you are ready to use again!

    So excited I found your page! I have my starter and will be making bread on Friday. I’m a “gram” girl. Do you know how many grams are in one cup of starter?
