Create your own organic sourdough starter from scratch with just a few simple ingredients. This all-natural and homemade starter will become the heart of your sourdough bread baking adventures, infusing your loaves with that distinctive tangy flavor.
In a 4+ cup jar/bowl, add ¼ cup whole wheat flour and ¼ all-purpose flour. Whisk together to combine.
Add ¼ cup room temperature spring water and stir with a fork until you don't see any dry flour.
Cover with a breathable lid or covering and store in a warm spot in the kitchen (I put mine on top of the refrigerator or on top of the hutch).
Leave for 24 hours.
Day 2
You probably won't see much happening on day 2. Maybe a few bubbles. Leave covered for another 24 hours.
Day 3
By day 3 you should be seeing plenty of bubbles and some expansion in your starter.
Remove half of the starter and set aside in a separate container in the fridge for a future discard recipe.
Feed your starter: add ¼ cup all-purpose flour and ¼ room temperature spring water. Stir until no dry flour is visible.
Cover starter again and put it back in its warm place for another 24 hours.
Days 4-5 (but maybe 4-7)
From this point on you should see lots of activity from your starter (lots of bubbling and expansion).
Every 24 hours, remove half of the starter and feed the original jar (¼ flour + ¼ water) and stir.
Float Testing
Starting on day 5, given there is plenty of activity in your starter, you should be checking to see if it is ready to use.
To perform a float test, fill a cup with water and drop a small dollop of starter in. If the starter floats, it's ready. If it doesn't float, feed again and check again in 24 hours.
Notes
If by day 3 you're not seeing lots of bubbly activity in your starter, feed it twice a day to give it an oomph.
