👩‍🍳 Step-by-Step Instructions

Day 1: Start the Culture

  1. In a clean jar, mix ½ cup whole wheat flour with ¼ cup water.
  2. Stir until a thick, smooth paste forms (no dry flour pockets).
  3. Cover loosely with a paper towel or lid and let sit at room temperature (70–75°F ideal) for 24 hours. 😊

Day 2: First Feeding

  1. You may see small bubbles — or none yet. That’s okay!
  2. Discard half of the mixture.
  3. Add ½ cup all-purpose flour and ¼ cup water. Stir well.
  4. Cover loosely and rest 24 hours.

Days 3–5: Feed Daily

  1. Discard half each day.
  2. Feed with ½ cup flour + ¼ cup water.
  3. By day 4 or 5, it should smell slightly tangy and show steady bubbling. ✨
  4. Use a rubber band to track how much it rises.

When Is It Ready?

Your starter is ready when:

  • It doubles in size within 4–6 hours after feeding
  • It smells pleasantly sour (not rotten)
  • It’s bubbly and airy throughout

💡 Pro Tips

  • Warm Spot: If your kitchen is cold, place the jar near a warm appliance.
  • Consistency: Starter should look like thick pancake batter. Adjust water slightly if needed.
  • Storage: Once active, store in the fridge and feed weekly.
  • No Waste Option: Use discard in pancakes, waffles, or crackers.

🔄 Variations

  • Use all whole wheat flour for a stronger flavor.
  • Try rye flour for faster fermentation.
  • Switch to bread flour once established for stronger gluten structure.

❓ FAQ

Why do I discard half?
Discarding keeps the starter manageable and properly fed.

What if it smells bad?
A strong sour smell is normal. Mold or a rotten smell means you should start over.

Can I speed it up?
Warmer temperatures (not hot!) help fermentation move faster.

What if I miss a feeding?
Just resume regular feedings. It’s more forgiving than you think!
