Sourdough Ranching

Step-by-Step Instructions for using a freeze-dried sourdough starter

With a little patience, it is easy to rehydrate and activate a freeze-dried sourdough starter.

What You will Need: • freeze-dried sourdough starter • Unbleached flour (can be all purpose, whole-wheat, or bread flour, preferably organic) • Non-chlorinated water (filtered or bottled water works best) • A clean jar or container with a lid • A small spoon, fork or spatula for mixing

Day 1: Rehydrate the Starter

Rehydrate your starter

  1. Add the starter to your glass jar.
  2. Add 2oz lukewarm or room temperature water (around 75–85°F).
  3. Add 1.5oz flour and stir well. Try to break up the big lumps. Let it sit for 30 minutes to 1 hour then stir again - this helps to fully mix up the yeast in the starter with the flour and water. Cover loosely with a lid or plastic wrap and let it sit at room temperature for 24 hours.

Check for activity

Day 2-3: Check for activity

You might see small bubbles or notice a slight sour smell—this is a good sign. If not, don’t worry; it can take a few days to wake up - this depends on the room temperature. If the room temperature is high, and you see many bubbles, move to the next step to feed the starter.

Day 3-4: Feed the starter

Add 1 oz of flour and 1 oz of water. Mix well. Cover loosely and let it sit for another 12–24 hours. You should start to see more bubbles.

Day 4–6: Strengthen the Starter

  1. Repeat feedings twice a day: Discard half of the starter and feeding it with equal amounts of flour and water every 12 hours.
  2. Look for signs of activity: The starter should start doubling in size within 4–6 hours of feeding, have a bubbly texture, and develop a pleasant sour aroma.

When is the Starter is Ready?

Your starter is fully active and ready to use when: • It doubles in size consistently within 4–6 hours of feeding. • It has a bubbly surface and a slightly tangy smell. At this point, you can use it for baking or store it in the refrigerator for future use. Make sure to feed it weekly if refrigerated.
