Ingredients You'll Need

How to Make Sourdough Starter
Step 1: Mix Initial Ingredients
In a wide-mouth 4-cup jar or bowl, combine ¼ cup wheat flour with ¼ cup all-purpose flour. Add the water and stir until you see no dry flour. Cover loosely and leave it in a warm spot for 24 to 48 hours.
Step 2: Check and Stir
On Day 2, check for any signs of activity such as bubbles. Stir the mixture if necessary and let it sit for another 24 hours.
Step 3: Feed the Starter
If you notice bubbles on Day 3, discard half of the starter. Add ½ cup all-purpose flour and ¼ cup lukewarm water. Stir to combine, cover loosely, and rest for another 24 hours.
Step 4: Continue Daily Feeds
From Days 4 to 7, discard half of the starter each day and feed with ½ cup flour and ¼ cup water daily. By Day 7, your starter should be ready.
Step 5: Test for Readiness
To test if your starter is ready, see how long it takes to double in size or perform the float test. If it passes, it's ready to use in baking.

Pro Tips from My Kitchen
✓ Use Quality Flour – The quality of flour can affect your starter's health, so choose fresh, unbleached varieties for best results.
✓ Maintain Consistent Warmth – Consistent warmth is key. A warm spot in your kitchen helps the fermentation process.
✓ Adjust Hydration as Needed – If your starter is too runny, reduce water slightly or add more flour at feedings.
✓ Be Patient – Fermentation is a slow process. Give it more time if you don’t see bubbles at first.
✓ Smell and Visual Check – Keep an eye on texture and smell; a healthy starter should be bubbly and have a pleasant tangy aroma.
Serving Ideas and Variations
- Your fresh sourdough starter can be used to make delicious artisanal bread with chewy crusts and deep flavors.
- Use your starter in pancakes or waffles for a tangy twist and improved texture.

After it's ready, store your starter in the fridge. Feed it once a week to keep it active.
A foul smell might indicate contamination. Ensure that no mold or pinkish hue is apparent and consider starting over with fresh ingredients.
Sourdough bread pairs well with savory soups, can be topped with your favorite spreads, or simply enjoyed as is, freshly baked.
