Hereโs a simple, no-fuss method for making your own sourdough starter from scratch using just flour, water, and time. In about 5โ7 days, youโll have a bubbly, active starter ready to leaven bread naturally โ no commercial yeast needed.
๐พ Homemade Sourdough Starter
๐งพ Youโll Need:
-
Flour โ unbleached all-purpose or whole wheat (or a mix)
-
Water โ filtered or dechlorinated (room temp)
-
A clean jar or container
-
A kitchen scale (strongly recommended for accuracy)
-
Optional: breathable cover (cloth, coffee filter, or loose lid)
๐ Day-by-Day Instructions:
๐น Day 1: Start the Culture
-
Mix:
-
60g flour (about 1/2 cup)
-
60g water (about 1/4 cup)
-
-
Stir into a paste in a jar. Scrape down the sides and loosely cover.
-
Let sit at room temperature (70โ75ยฐF / 21โ24ยฐC) for 24 hours.
๐น Day 2: First Feeding
-
You might see a few bubbles โ or nothing yet (totally normal).
-
Discard half the starter (about 60g).
-
Add:
-
60g flour
-
60g water
-
-
Stir, cover loosely, and rest another 24 hours.
๐น Days 3โ5: Feed Daily
-
Repeat the process every 24 hours:
-
Discard half (or keep it for discard recipes).
-
Feed with equal parts flour and water (by weight).
-
-
By day 4 or 5, you should see more bubbles, mild rise, and a sour smell.
๐น Day 6โ7: Ready or Almost Ready
-
Your starter is ready when it:
-
Doubles in size within 4โ6 hours of feeding
-
Smells tangy and pleasant (not off or rotten)
-
Has a bubbly, slightly stretchy texture
-
โ Do the float test: Drop a spoonful into water. If it floats, itโs airy and active!
๐ Feeding Schedule (After Maturity):
If baking daily:
-
Feed once every 24 hours at room temp.
If baking weekly:
-
Store in the fridge, feed once per week.
-
Before baking, take it out, feed it 1โ2 times at room temp to reactivate.
๐ Tips:
-
Whole wheat or rye flour can help boost fermentation early on.
-
If it smells like nail polish or rotten cheese โ donโt worry! Itโs likely just hungry. Feed it.
-
Always use clean utensils and containers.
