Step-by-Step Instructions for Making Your Own Sourdough Starter

By Mateo Rodríguez

Understanding Sourdough: A Brief Overview

Sourdough is a type of bread made by the fermentation of dough using naturally occurring lactobacilli and yeast. Unlike commercial breads that use baker's yeast, sourdough relies on wild yeast to rise. The result is a rich, tangy loaf with a chewy texture and complex flavor.

Creating your own sourdough starter at home is not just about making bread; it’s about cultivating a living culture that requires care and attention. This process may seem daunting at first, but with patience and a few simple ingredients, you can create a starter that will last for years and provide endless delicious loaves.

Gathering Your Ingredients and Tools

The first step in making your sourdough starter is gathering the right ingredients and tools. Fortunately, you don’t need much to get started:

• Flour: Use whole grain flour such as whole wheat or rye to start your culture. These flours contain more natural yeast and bacteria than all-purpose flour, which will help kickstart the fermentation process.
• Water: Use non-chlorinated water. Chlorine can kill the beneficial bacteria needed for fermentation. Filtered or distilled water works best.
• Jar or Container: Choose a clear container so you can easily monitor the starter's progress. A mason jar is perfect.
• Spoon or Spatula: A non-metal spoon or spatula to mix the ingredients.

Day-by-Day Instructions for Creating Your Starter

Day 1: Begin the Fermentation

Ingredients:

• 50g whole grain flour
• 50g water

Instructions:

1. Add the flour and water to your jar. Stir until there are no dry bits of flour. The consistency should resemble thick pancake batter.
2. Cover the jar loosely with a lid or cloth to allow air circulation while keeping out dust and insects.
3. Place the jar in a warm spot, ideally between 70°F and 75°F (21°C to 24°C).

Tip: Temperature is key. If your kitchen is too cold, fermentation will slow down significantly. A warm spot above the refrigerator or near a radiator might help.

Day 2: Observe and Refresh

You might see a few bubbles by now—this indicates that fermentation has started!

Instructions:

1. Discard half of the starter (about 100g). This keeps the acidity in check and maintains the balance of yeast and bacteria.
2. Add 50g of fresh whole grain flour and 50g of water. Stir well to combine.

Your starter should still be in the same warm spot. Cover it as before.

Days 3-5: Continue Feeding

By now, the starter should have more bubbles, and possibly a pleasant aroma.

Instructions for Each Day:

1. Repeat the Day 2 instructions: Discard half and feed with equal parts flour and water.

If all goes well, your starter will become more active each day, with more bubbles and an increasingly sour smell.

Maturing Your Starter

Day 6-7: Establish Routine Feeding

Your starter should be almost ready. It should double in size within 4-6 hours after feeding. If this isn't happening yet, continue daily feedings for a few more days.

If it's ready, here's how to maintain it:

• If baking regularly (every day or two), keep feeding daily at room temperature.
• If baking less frequently, store it in the refrigerator and feed once a week.

Troubleshooting Common Issues

• If you see a liquid on top ("hooch"), it’s hungry—simply feed it without discarding extra hooch.
• If mold develops, discard the starter and begin again.

Baking Your First Loaf of Sourdough Bread

Kneading the Dough

The art of kneading is crucial for developing gluten in your dough. Here’s how:

• Use your hands to gently stretch and fold the dough on a floured surface.
• The goal is not to add too much flour; the dough should remain slightly sticky but manageable.

Shaping the Loaf

This step determines your loaf's final shape. Follow these steps:

1. Pre-shape into a round by folding edges toward the center.
2. Let it rest for 10 minutes covered by a towel.

Finally, shape into your desired form—whether it's a classic boule or a batard—by gently stretching the dough into shape without deflating it.

Baking Tips for Perfection

Preheat your oven with a Dutch oven inside to 450°F (232°C).

• Score the top of your loaf with a sharp blade. This allows steam to escape during baking.
• Bake covered for 20 minutes, then uncover to finish until golden brown (about 25 more minutes).

Tip: For extra crispness, spray some water into the oven just before closing the door to create steam.

Caring for Your Sourdough Starter Long-Term

A sourdough starter can last indefinitely if properly maintained. Here’s how:

• Keep it in the fridge if not used regularly. Feed every week to keep it healthy.
• If planning to bake, take it out and feed daily three days prior to reactivate it.

Sourdough is more than just bread—it's a journey into culinary tradition, science, and care. Once you've mastered these steps, feel free to experiment with different flours and hydration levels to make sourdough uniquely yours.
