Freezing Sourdough Starter
Step 1: Feed your starter and wait until it’s at its peak before freezing.
Step 2: Make sure your ice cub trays or silicone molds are clean and dry.
Step 3: Carefully portion into small freezer-safe containers or silicone trays. I like to have a tray or baking sheet underneath my ice cube tray just in case it spills in the freezer. This will depend on your freezer space.
Step 4: Wait 8-12 hours to make sure it's completely frozen.
Step 5: Pop your frozen starter out of the tray or mold and store in a labeled, freezer-safe bag.
Thawing Frozen Sourdough Starter
Step 1: Pop out a cube or portion, place in a mason jar. Place in fridge overnight or thaw at room temperature. I chose to thaw mine at room temperature to speed up the process.
Step 2: Once it is thawed, give your starter a gentle stir.
Step 3: Feed with equal parts flour and warm water. I did 50 g of filtered water and 50 g flour. Mix it up well and cover with a loose lid and set it in a warm spot.
Step 4: Let your starter sit at room temperature for 4–12 hours depending on the temperature of your home.
Step 5: Now, continue regular feedings daily for 2–3 days until it shows signs of activity, which is very bubbly and doubling. This will all despond on how string your starter was before you froze it. Once it looks up to optimal strength, you can bak with it!
