Jennie’s Thoughts

Starting a sourdough starter always felt intimidating to me at first — like it required some secret baking magic. But once I tried this easy method, I realized it’s just about consistency and patience.

I love seeing my starter bubble and grow each day — it’s like having a little kitchen companion. And the flavor it adds to homemade bread is unbeatable. Once you try baking with your own starter, you’ll never want store-bought yeast again!

Ingredients

• ½ cup all-purpose flour (or bread flour)
• ¼ cup filtered water (room temperature)

Optional: a pinch of sugar to help jump-start fermentation (especially in cooler kitchens)

How to Make Your Sourdough Starter

Day 1: Mix

1. In a clean jar or bowl, combine ½ cup flour and ¼ cup water.
2. Stir until smooth and no dry flour remains.
3. Cover loosely with a clean cloth or lid (don’t seal tightly).
4. Let sit at room temperature for 24 hours.

Day 2–7: Feed

1. Each day, discard about half of the starter (roughly ½ cup).
2. Add ½ cup fresh flour and ¼ cup water.
3. Stir until smooth and cover again.
4. By day 4–7, you should see bubbles forming, a pleasant sour smell, and your starter should double in size after feeding.

Ready to Use

Once your starter is bubbly and doubles in size within 6–8 hours of feeding, it’s ready for baking! Use it immediately in sourdough bread, pancakes, waffles, or any recipe that calls for a sourdough starter.

Float Test: Is Your Starter Ready?

The float test is an easy way to check if your sourdough starter is ready to bake with:

1. Fill a small bowl with room temperature water.
2. Take about 1 teaspoon of your starter and gently drop it into the water.
3. If the starter floats, it’s full of air bubbles and ready to use.
4. If it sinks, it needs a little more time and feedings before baking.

Tip: Timing is everything! Even if your starter passes the float test, make sure it’s at peak activity—bubbly, doubled in size, and slightly sour-smelling—for the best bread rise.

Tips for Success

• Keep your starter at room temperature for best results.
• Use filtered water if your tap water is heavily chlorinated.
• Stir your starter daily to incorporate air and encourage bubbles.
• If not baking daily, store the starter in the fridge and feed once a week.

Making a sourdough starter from scratch doesn’t have to be intimidating. With just flour, water, and patience, you can create a living starter that will give your bread a depth of flavor you can’t get from store-bought yeast.

Once your starter is active and bubbly, you’ll feel empowered to bake soft, crusty, tangy sourdough loaves right at home. It’s fun, rewarding, and a little magical — and your kitchen will smell amazing the whole time!
