Method

Build the Sponge

Create a bubbly, active sponge that provides flavor and leavening.

1. Combine flour and water. Add bread flour (280g) and warm water (210g) to a large bowl. Mix until no dry flour remains. The mixture will be thick but stirrable.
2. Add yeast. Sprinkle the instant yeast over the surface and stir until evenly distributed.
3. Cover loosely. Use plastic wrap or a damp towel. The sponge needs room to expand.
4. Ferment. Leave at warm room temperature (78-82°F) for 3-5 hours. Ready when doubled, domed, bubbly, and smells yeasty.

Wait: 3-5 hours

Tip: This wide timing window is sponge's advantage—it's very forgiving.

Mix the Final Dough

Combine all ingredients and develop smooth, elastic gluten.

1. Add sponge to mixer. Scrape all of the sponge into the bowl of a stand mixer fitted with the dough hook.
2. Add remaining ingredients. Add fresh bread flour (280g), room temperature milk (115g), softened butter (45g), sugar (35g), salt (10g), and instant yeast (3g).
3. Mix on low. Mix on low speed (speed 2) for 3 minutes until everything comes together into a rough dough.
4. Develop gluten. Increase to medium speed (speed 4) and mix for 6-8 minutes until smooth and passes the windowpane test.

Tip: Target dough temperature: 78-80°F. The enrichments slow fermentation, so a warmer dough helps.

Bulk Fermentation

Let the dough double—no folds necessary.

1. Prepare for rising. Transfer dough to a lightly oiled bowl. Cover with plastic wrap.
2. Ferment. Ferment at warm room temperature (78-82°F) until doubled in size, about 1-1.5 hours.
3. Check readiness. Press gently with a floured finger. If the indent springs back slowly, it's ready.

Wait: 1-1.5 hours

Divide and Pre-Shape

Portion the dough and let it relax.

1. Divide. Turn onto a lightly floured surface. Divide into two equal pieces (approximately 530g each).
2. Pre-shape. Gently pat each piece into a rough rectangle, then fold in thirds like a letter. Flip seam-side down.
3. Rest. Cover loosely and rest 10 minutes to relax the gluten.

Shape for Pan

Roll into tight logs for even slices.

1. Prepare pans. Lightly butter or spray two 9x5 inch loaf pans.
2. Shape each loaf. Flip dough seam-side up. Press or roll into a rectangle about 8 inches wide by 12 inches long.
3. Roll. Starting from a short end, roll the dough tightly toward you, creating a log. Pinch the seam to seal.
4. Pan. Pinch ends and tuck under. Place seam-side down in prepared pans. Dough should fill about half the pan.

Final Proof

Let loaves rise until they crown above the pan rim.

1. Cover. Cover loosely with plastic wrap or a damp towel.
2. Proof. Proof at warm room temperature until dough crowns about 1 inch above the rim of the pan (45-60 minutes).
3. Test readiness. Poke gently with a floured finger. Indent should spring back slowly and mostly fill in. Don't over-proof.

Wait: 45-60 minutes

Tip: Sandwich bread that over-proofs will collapse during baking. When in doubt, bake sooner.

Shaping

Classic loaf shaping for even slices and great oven spring.

Pan Loaf (recommended)

Traditional sandwich loaf shape for even slices.

1. Prepare pans. Lightly butter or spray two 9x5 inch loaf pans.
2. Shape loaf. Flip dough seam-side up. Press or roll into an 8x12 inch rectangle.
3. Roll tightly. Starting from short end, roll toward you into a tight log. Pinch seam to seal.
4. Pan loaves. Pinch ends and tuck under. Place seam-down in pans—dough should fill about half.

Baking

Bake until deep golden and internal temperature reaches 195-200°F.

Standard Oven (recommended)

Bake until deep golden brown with internal temp of 195-200°F.

Equipment: Two 9x5 inch loaf pans,Oven

1. Preheat. Preheat oven to 375°F (190°C) during last 20 minutes of proofing.
2. Optional egg wash. Beat egg with water and brush gently over tops for a golden, glossy crust.
3. Bake. Place pans on middle rack with space between. Bake 30-35 minutes until deep golden brown.
4. Check doneness. Internal temperature should reach 195-200°F. If tops brown too quickly, tent with foil at 25 minutes.
5. Cool. Rest in pans 5 minutes. Turn out onto wire rack. Cool completely before slicing—at least 1 hour.

Note: Cutting too early results in gummy, compressed slices. Let the crumb set completely.

Storage

• Room temperature: 4 days at room temperature in a plastic bag or bread box.
• Frozen: Up to 2 months. Slice before freezing. Toast frozen slices directly.

For softer crust, brush hot loaves with melted butter immediately after baking.

Frequently Asked Questions

Can I use active dry yeast instead of instant?

Yes. Bloom it in the warm water for 5-10 minutes before adding flour.

What if my sponge has collapsed?

A slightly collapsed sponge is still usable—it's just past peak. The flavor may be slightly more complex. Proceed normally.

How do I know when it's done baking?

Internal temperature should reach 195-200°F. The crust should be deep golden brown and feel rigid.

Why did my loaves collapse?

Over-proofed—the gluten couldn't support the expansion. Proof for less time next time, and bake when dough still has some spring left.

My crumb has large holes. What happened?

The dough wasn't shaped tightly enough, trapping air pockets. Roll more snugly next time and press out large bubbles during shaping.
