The Essential Tools and Ingredients for Sourdough Sandwich Bread

Before you start making sourdough sandwich bread, it’s important to have the right tools and ingredients on hand. This will ensure that your baking process goes smoothly and that you achieve the desired texture.

Tools You’ll Need:

  • Digital kitchen scale: Precision is crucial in sourdough baking, as slight variations in ingredient weights can significantly impact the final result.
  • Stand mixer or large mixing bowl: A stand mixer can help knead the dough, but you can also mix and knead by hand.
  • Loaf pan: Use an 8.5″ x 4.5″ loaf pan to shape the dough into a perfect sandwich loaf.
  • Bench scraper: Handy for dividing and shaping the dough.
  • Dough scraper: For easy handling of sticky dough.

Ingredients You’ll Need:

  • Sourdough starter: Your sourdough starter must be active and bubbly. To test if it’s ready, perform a float test—drop a small portion of starter in water. If it floats, your starter is ready to use.
  • Bread flour: While all-purpose flour can be used in a pinch, bread flour is preferred for its higher protein content, which helps develop gluten and provides a stronger structure. For more information on flour types, check out this detailed flour guide.
  • Water: Use room-temperature water for proper hydration and fermentation.
  • Butter: This ingredient softens the crumb and adds richness to the loaf.
  • Salt: Enhances flavor and strengthens gluten.
  • Sugar or honey: Optional, but it adds a touch of sweetness and helps with browning.

Having a precise understanding of your ingredients will help you avoid common issues like dense loaves or insufficient rise. Bread flour, for instance, is ideal for giving your bread structure, especially when making a soft loaf like sandwich bread. For more insights into flour choices, check here.


Preparing Your Sourdough Starter

If you haven’t yet created a sourdough starter, you’ll need to begin by developing one from scratch. A starter is a mixture of flour and water that captures wild yeast and bacteria from the environment, naturally fermenting over time. Here’s how to get your starter ready for sourdough sandwich bread:

How to Make a Starter:

  1. Mix equal parts flour and water in a clean jar, using whole wheat or rye flour to get things going.
  2. Cover loosely and leave in a warm spot. Stir daily and discard half of the mixture before adding more flour and water in equal parts.
  3. In 5-7 days, your starter should become bubbly and active. It should have a pleasant, slightly tangy smell and double in size a few hours after feeding.

Feeding Your Starter:

Once your starter is active, it must be fed regularly to stay healthy and ready for baking. If kept at room temperature, feed it daily. If stored in the fridge, feed it once a week. Always make sure your starter is at its peak activity before using it in a bread recipe. A good way to check is by doing the float test—if it floats, it’s ready to go.


Step-by-Step Sourdough Sandwich Bread Recipe

Now that your starter is ready, let’s dive into the full recipe. Below, you’ll find a detailed step-by-step guide that will help you create a perfect loaf of sourdough sandwich bread.

1. Mixing the Dough

In a large mixing bowl or stand mixer, combine the following ingredients:

  • 630g bread flour
  • 340g water
  • 100g active sourdough starter
  • 42g butter, softened
  • 50g sugar (or honey)
  • 15g salt

Mix everything together until a shaggy dough forms. If you’re using a stand mixer, knead the dough on medium speed for 6-8 minutes until it becomes smooth and elastic. If kneading by hand, expect the process to take a bit longer. The dough should pass the windowpane test, which means you can stretch it thin enough to see through without tearing.


2. Bulk Fermentation (First Rise)

Once the dough is kneaded, transfer it to a greased bowl, cover it with a kitchen towel or plastic wrap, and allow it to rise at room temperature for 8-12 hours. This step is called bulk fermentation, during which the dough ferments, develops flavor, and rises.

The dough should double in size during this time. The duration of the bulk fermentation may vary depending on the temperature of your kitchen. In warmer conditions, the dough may ferment faster, while in colder environments, it could take longer. If your dough hasn’t doubled in size, give it more time to rise.


3. Shaping the Dough

Once the dough has completed its first rise, turn it out onto a floured surface. If you’re making two loaves, divide the dough into two equal pieces.

Here’s how to shape the dough for a sandwich loaf:

  • Roll each portion into a rectangle.
  • Tightly roll the dough into a log, pressing down as you go to create surface tension. This will help the dough hold its shape during baking.

Place the rolled dough seam-side down into a greased loaf pan. The dough should fit snugly in the pan, ensuring a uniform rise and shape.


4. Proofing the Dough (Second Rise)

Cover the loaf pan with a damp towel or plastic wrap and let the dough rise at room temperature for 2-4 hours, or until it rises just above the rim of the loaf pan.

The proofing time can vary depending on the activity of your sourdough starter and the temperature of your kitchen. Use the “poke test” to check if the dough is ready to bake. Gently press the dough with your finger—if it springs back slowly, it’s ready. If it springs back quickly, give it more time to rise.


5. Baking the Loaf

Once your dough has risen sufficiently, it’s time to bake. Preheat your oven to 375°F (190°C). You can brush the top of the dough with melted butter or milk before baking to give it a golden, glossy crust.

Place the loaf in the oven and bake for 30-35 minutes, or until the top is golden brown. The internal temperature of the bread should reach around 190°F (88°C) when fully baked. To avoid overbaking, you can use an instant-read thermometer to check the internal temperature.

Remove the loaf from the oven and allow it to cool in the pan for about 5-10 minutes before transferring it to a wire rack to cool completely. Letting the bread cool fully will help the crumb set, making it easier to slice.

Variations and Customizations

Once you’ve mastered the basic sourdough sandwich bread recipe, you can begin experimenting with various add-ins and substitutions to create different flavors and textures.

Popular Variations:

  • Whole Wheat Sourdough: Replace up to 50% of the bread flour with whole wheat flour for a more hearty, dense loaf. Whole wheat flour adds a nutty flavor and more nutrition to your bread.
  • Honey-Sweetened Sourdough: Swap the sugar for honey or maple syrup to give your loaf a naturally sweet flavor that pairs beautifully with toast or sandwiches.
  • Seeded Sourdough: Add flaxseeds, sunflower seeds, or sesame seeds to the dough or sprinkle them on top for extra crunch and flavor. This is a great way to enhance the texture of your bread.

Customizing your sourdough sandwich bread allows you to create a loaf that suits your specific tastes and dietary preferences, all while maintaining the soft, sandwich-perfect crumb.

Storage and Freezing Tips

Once you’ve baked your sourdough sandwich bread, it’s important to store it properly to keep it fresh and ready to enjoy for as long as possible.

How to Store Sourdough Sandwich Bread

Room Temperature Storage: After your bread has completely cooled, you can store it at room temperature for up to five days. To maintain freshness, keep the loaf in a bread bag, plastic wrap, or an airtight container. Storing it in a cool, dry place like a bread box helps protect it from humidity, which can cause mold. Avoid refrigerating the bread, as this can cause it to dry out faster and lose its softness.

Freezing Instructions

Freezing is a great way to extend the life of your homemade sourdough sandwich bread. Here’s how to freeze it properly:

  • Allow the bread to cool completely.
  • Slice the loaf before freezing if you plan to use individual slices later. This makes it easy to grab just a slice or two, rather than thawing the entire loaf.
  • Wrap the loaf or slices tightly in plastic wrap to prevent freezer burn.
  • Place the wrapped bread in a freezer-safe plastic bag or an airtight container to keep it fresh in the freezer for up to 3 months.

Thawing Sourdough Bread

When you’re ready to enjoy your bread, remove the slices or loaf from the freezer and allow them to thaw at room temperature. If you’re in a rush, you can pop individual slices directly into the toaster. For a whole loaf, let it thaw completely before warming it up in the oven at 350°F for about 10-15 minutes to refresh the crust and soften the crumb.


Troubleshooting Common Issues

Baking sourdough can sometimes present challenges, especially if you’re new to working with sourdough starter. Below are solutions to some common issues bakers encounter when making sourdough sandwich bread.

Why Didn’t My Bread Rise?

There are a few common reasons why your sourdough sandwich bread might not rise properly:

  • Inactive Starter: Your sourdough starter might not be strong enough to give the dough the rise it needs. Make sure your starter is bubbly and active before incorporating it into the dough. Perform a float test to confirm readiness: drop a small piece of starter into a bowl of water. If it floats, it’s ready to use; if it sinks, feed it again and wait a few hours.
  • Cold Environment: Sourdough fermentation is sensitive to temperature. If your kitchen is too cold, the dough will take longer to rise or may not rise at all. Aim for a room temperature of around 70-75°F (21-24°C) to ensure proper fermentation. You can also try placing the dough in a warmer spot, like inside an oven with just the light on, or near a warm appliance.

Why Is My Bread Dense?

A dense loaf can be caused by a variety of factors, but here are the most common culprits:

  • Under-proofing: If your dough hasn’t risen enough during the bulk fermentation or proofing stages, it won’t develop enough structure, leading to a dense crumb. Make sure the dough doubles in size during the first rise and that it’s puffy during the second rise.
  • Gluten Development: If the dough wasn’t kneaded long enough, the gluten network won’t be strong enough to hold the gas produced during fermentation, resulting in a dense texture. Ensure you knead the dough until it passes the windowpane test—stretching the dough thin enough to see through without tearing.

Why Is My Crust Too Hard for Sandwiches?

If the crust on your sandwich bread turns out too thick or tough, here are a few tips to help soften it:

  • Steam in the Oven: Adding steam to the oven can help soften the crust. You can place a small tray of water at the bottom of the oven during the first 10-15 minutes of baking.
  • Brushing the Dough: Before baking, brush the dough with melted butter or milk. This will help soften the crust and give it a rich, golden color.

FAQs: Common Questions About Sourdough Sandwich Bread

1. How Long Does Sourdough Sandwich Bread Take to Make?

Making sourdough sandwich bread is a slow process because of the natural fermentation. From start to finish, it can take anywhere from 12-24 hours depending on how long you allow the dough to rise. However, most of this time is inactive, as the dough is left to ferment and proof.

2. Can I Use All-Purpose Flour Instead of Bread Flour?

Yes, you can use all-purpose flour if you don’t have bread flour on hand. However, bread flour has a higher protein content, which helps develop more gluten and gives the bread a chewier texture. Using all-purpose flour might result in a slightly softer loaf with less structure.

3. Can I Add Ingredients Like Honey or Seeds?

Absolutely! Adding honey or seeds to your dough is a great way to customize your bread. Honey adds a mild sweetness, while seeds like flaxseeds or sunflower seeds add crunch and extra flavor. Simply add them in when mixing your dough, or sprinkle seeds on top before baking.

4. How Can I Make My Bread Softer?

For a softer loaf, try adding more fat to the dough. Ingredients like butter or milk help soften the crumb and give the bread a rich, tender texture. Adding an egg to the dough can also contribute to a softer result, but this will slightly change the flavor profile.

5. Can I Freeze Sourdough Sandwich Bread?

Yes, sourdough bread freezes very well. Just make sure to let it cool completely before wrapping it in plastic and placing it in a freezer-safe bag. It can last for up to 3 months in the freezer. When you’re ready to eat it, let it thaw at room temperature or warm it up in the oven.


Advanced Tips for Sourdough Enthusiasts

Once you’ve mastered the basics of sourdough sandwich bread, there are several ways to take your bread-making skills to the next level. Here are a few advanced techniques to explore:

Experimenting with Higher Hydration

Higher hydration (more water in the dough) leads to a more open crumb structure, which is especially appealing in sourdough baking. However, handling high-hydration dough requires practice, as it can be stickier and harder to shape. Start by gradually increasing the water content in your dough to see how it affects the final loaf.

Adding Flavor Inclusions

Once you’ve perfected your basic loaf, you can start experimenting with inclusions like dried fruits, herbs, or cheeses to add more complexity to the flavor. Try adding dried cranberries, rosemary, or even cheddar to your dough during the last round of mixing for a unique twist on the traditional loaf.

Controlling Fermentation for Flavor

The length of fermentation has a big impact on the flavor of sourdough bread. If you prefer a tangier loaf, extend the fermentation time by allowing the dough to proof in the fridge overnight. For a milder flavor, reduce the fermentation time or feed your starter more frequently to mellow out the sour notes.


Conclusion: Your Perfect Loaf Awaits

With the right tools, ingredients, and techniques, making sourdough sandwich bread at home is a fulfilling and delicious experience.
