Sourdough Starter Basics
Cultivating a starter is an exercise in patience rather than skill. You are building a stable ecosystem that will eventually act as the leavening agent for your bread.
Consistency is your primary ingredient.
Use a digital scale to ensure your ratios are exact. A warmer kitchen will speed up the process, while a cold room will slow the yeast activity.

What goes in.
- 50gwhole rye or whole wheat flour
- 50groom temperature filtered water
Maintaining Balance
Discarding half the mixture before every feed prevents your jar from overflowing and ensures you aren't trying to feed a massive, inactive population of yeast.
The method.
Mix the initial starter
Combine 50g of whole flour and 50g of water in the jar. Stir until no dry streaks remain. Cover loosely and set aside at room temperature for 24 hours.
The first feed
After 24 hours, discard half of the mixture. Add 50g of bread flour and 50g of water to the jar. Stir well and cover.
Establish the routine
Repeat the discard and feed process every 24 hours. Use unbleached bread flour for feedings to keep the yeast robust.
Observe the signs
Watch for small bubbles near the surface and a slight change in scent. By day four or five, you should notice the mixture rising and falling.
Verify maturity
The starter is ready to bake with when it consistently doubles in volume within 4 to 6 hours of feeding and smells like fresh, slightly tangy dough.
Other turns to take.
Rye Starter
Using rye flour for every feeding makes for a very active, fast-growing starter with a deep, earthy scent.
Cold Storage
Once established, keep the starter in the refrigerator and feed it once a week to maintain it without the daily commitment.
When it doesn't go to plan.
Always weigh your ingredients; volume measurements like cups are too inaccurate for fermentation.
Use a rubber band around the outside of the jar to mark the level of the starter after feeding so you can easily track its growth.
If a dark liquid forms on top, known as hooch, the starter is hungry. Pour it off and feed immediately.
The ones that keep coming up.
Does it matter if I use tap water?
If your tap water is heavily chlorinated, it may inhibit yeast growth. Use filtered water to be safe.
What should I do with the discard?
Keep it in a separate jar in the fridge until you have enough to incorporate into pancakes, crackers, or other recipes.
