Authentic Bread Flavor

Henry Hunter Jr. is the founder of Crust & Crumb Academy and the Baking Great Bread at Home community. This sourdough version uses a sweet levain to solve the sourness problem that keeps most bakers away from sourdough enriched doughs.

Equipment Needed

Stand mixer with dough hook (optional)
9×13 inch baking pan
Small saucepan (for tangzhong and glaze)
Digital kitchen scale
Pastry brush
Piping bag or zip-lock bag (for flour paste cross)
Instant-read thermometer

Ingredients

Scale Recipe:

Sweet Levain

Build this 8–10 hours before mixing. The sugar feeds your starter quickly and produces a milder, less acidic levain — which means hot cross buns that taste spiced and sweet, not sour.

granulated sugar5g

Tangzhong (Water Roux)

Make this while the levain builds. Cool completely before using.

Pro Tip

Keep the cinnamon at this amount. More cinnamon = slower fermentation. Cinnamaldehyde, the compound that gives cinnamon its flavor, inhibits yeast activity. In a sourdough dough with fat, sugar, and eggs already slowing things down, too much cinnamon can stall the bulk fermentation completely.

8–10 hours before mixing

Build the Sweet Levain

A built with milk and a touch of sugar instead of plain water. The milk and sugar create a milder fermentation environment — less acetic acid, more lactic. The result is a levain that leavens well without making your buns taste sour.

1

Mix the levain

In a clean jar, combine the active starter, bread flour, lukewarm milk, and sugar. Stir until well combined — the mixture will be stiff. Close the lid loosely and leave at room temperature (75–78°F / 24–26°C).

2

Watch for peak

The levain is ready when it has doubled or more in size, is domed on top, and has visible bubbles throughout. This takes 8–10 hours at 75–78°F. A levain built with milk moves a little slower than one built with water — that's normal.

⏱ Wait Time

8–10 hours

Two types of acid

Sourdough produces two organic acids: lactic (mild, yogurt-like) and acetic (sharp, vinegary). Acetic acid is what most people mean when they say sourdough is 'too sour.' It develops more in cooler, drier, longer ferments. Lactic acid dominates in warmer, wetter, shorter ferments.

How this levain shifts the balance

By using milk instead of water (adding fat and protein) and a small amount of sugar (additional food for the yeast), we create a warmer, richer fermentation environment that favors lactic acid production over acetic. Lower inoculation (17%) also limits how long the fermentation runs before baking, which keeps acidity in check.

The cinnamon factor

Cinnamon slows yeast activity via cinnamaldehyde, a natural antifungal. In this recipe, that's actually an advantage for flavor control — the slower ferment means less acidity accumulates. It's a built-in brake on over-fermentation.

The Takeaway

Sweet levain + 17% inoculation + enriched dough = hot cross buns that taste like the recipe, not the starter.

Soak Fruit and Make Tangzhong

Do both of these while the levain is building. Both need to be cool before they hit the dough.

1

Soak the fruit

Combine currants and candied orange peel in a bowl. Pour the hot tea or orange juice over them. Cover and let soak at least 30 minutes. Drain well before using.

2

Make the tangzhong

Whisk 25g bread flour and 125g whole milk in a small saucepan until smooth. Heat over medium-low, stirring constantly, until the mixture thickens to a paste and reaches 65°C (149°F) — about 3–4 minutes. Press plastic wrap directly onto the surface and cool completely.

Mix

Mix the Dough

Build the dough once the levain is at peak — doubled, domed, and bubbly. Same method as the yeasted version: dry ingredients first, wet ingredients in, butter last, fruit after the gluten is built.

Progress

Click each step to mark complete

1

Combine dry ingredients

In your stand mixer bowl, whisk together the bread flour, sugar, salt, cinnamon, allspice, nutmeg, cardamom, and orange zest.

2

Add wet ingredients and levain

Add the lukewarm milk, eggs, cooled tangzhong, and all of the sweet levain. Mix on low with the dough hook for 2–3 minutes until a shaggy dough forms.

3

Add butter

Add softened butter in small pieces with the mixer running on low. Once incorporated, increase to medium-low and knead for 8–10 minutes until smooth and elastic. By hand: 12–14 minutes.

4

Add the fruit

Add the drained soaked fruit and mix on low for 2 minutes until evenly distributed. Don't overwork.

Pro Tip

This dough will feel stickier than a lean sourdough. That's the enrichment doing its job. Resist the flour. Let the mixer work.

Overnight Bulk

Overnight Bulk Fermentation

Overnight — Start the night before

The enriched dough ferments slowly overnight. Butter, eggs, and sugar all slow the yeast — which is actually an advantage here. Slow fermentation = better flavor, no over-fermentation risk.

Progress

1

Cover and ferment

Shape the dough into a ball, place in a lightly greased bowl, and cover with plastic wrap. Ferment at room temperature (75–78°F / 24–26°C) overnight, about 8–12 hours, until the dough has approximately doubled.

2

Check in the morning

The dough is ready when it's noticeably puffed, slightly jiggly when you shake the bowl, and a floured finger pressed in springs back slowly. If it springs back immediately, give it more time. If the indent stays, move on — it's at or past peak.

⏱ Wait Time

8–12 hours

Pro Tip

If your kitchen is warmer than 78°F, the bulk will go faster. Check at 6–7 hours. If your kitchen is cooler than 72°F, it may take up to 14 hours. The dough tells you when it's ready — watch the dough, not the clock.

Shape

Divide and Shape

Same technique as the yeasted version. Twelve equal buns, shaped tight, placed touching in the pan.

1

Divide

Punch down the dough gently and turn out onto a lightly floured surface. Weigh the total dough and divide by 12. Each bun should be approximately 85–90g.

2

Shape each bun

Pull the edges toward the center, rotating as you go, to build surface tension. Flip seam-side down. Cup your hand and roll in a tight circle on the surface until smooth and taut.

3

Arrange in pan

Place shaped buns in the greased 9×13 pan in a 3×4 grid with about ½ inch of space between each bun.

Proof & Cross

Final Proof and Flour Paste Cross

The final proof takes longer than the yeasted version — 2 to 3 hours is normal for a cold, enriched sourdough dough coming up to temperature. Don't rush it. Pipe the cross right before baking.

1

Final proof

Cover the pan loosely and let proof at room temperature (75–78°F) for 2–3 hours until the buns are visibly puffed, touching their neighbors, and spring back slowly when gently pressed.

2

Preheat

20 minutes before the end of the proof, preheat your oven to 400°F (200°C).

3

Make the flour paste cross

Whisk together the bread flour, water, and sugar until completely smooth. The paste should be thick enough to hold its shape when piped — like a stiff toothpaste. Adjust water by the teaspoon if needed.

4

Pipe the crosses

Transfer paste to a piping bag or zip-lock bag with a small corner snipped. Pipe one continuous line across each row of buns, then rotate 90 degrees and pipe across the columns. Pipe slightly thinner than you want — they spread a little in the oven.

5

Egg wash

Brush exposed dough (not the paste) with egg wash.

Bake and Glaze

Same bake as the yeasted version. Hot oven, short time, glaze immediately on exit.

Bake Time: 20–25 minutesOven: 400°F / 200°CInternal Temp: 190°F / 88°C

Step by Step

1

Bake

Bake at 400°F (200°C) for 20–25 minutes until deep golden brown. Internal temperature should reach 190°F (88°C).

2

Make the glaze

While the buns bake, combine the apricot jam (or orange marmalade) and water in a small saucepan over medium heat. Stir until smooth and runny.

3

Glaze immediately

Brush generously over the entire surface the moment the buns come out of the oven. Let cool in the pan for 10–15 minutes before pulling apart.
