Sourdough Chinese Donuts with Grilled Oregano Sugar & Lemon Glaze

What Makes This Special

These Chinese donuts (yóutiáo-inspired, but donut-shaped for enjoyment and portability!) use a lively sourdough starter for deep, complex flavor, and a light, airy texture—no commercial yeast needed. The warming aroma of grilled oregano sugar and a bright lemon glaze add a cooling, summery twist. Designed for sharing, these donuts are ideal for an office treat: easy to handle, eye-catching, and full of conversation-worthy technique.

Ingredients

Summer brings fresh herbs and vibrant citrus—here, grilled oregano infuses sugar with herbal-citrus notes, paired with sourdough’s subtle tang. Bread flour ensures structure for the high hydration dough, while honey and butter enrich every bite.

For the Sourdough Donut Dough

• 450g bread flour: Gives structure for light, chewy donuts.
• 60g all-purpose flour: Softens the crumb.
• 120g active sourdough starter (100% hydration): The natural leaven, providing rise and flavor.
• 260ml water: Hydrates for an open, soft interior.
• 50g granulated sugar: Adds sweetness and helps browning.
• 15g honey: Adds flavor depth and moisture.
• 10g fine sea salt: Balances flavor.
• 40g unsalted butter: Adds richness and soft crumb.
• 4g baking soda: Assists browning and puffing at fry time.

For Grilled Oregano Sugar

• 50g fresh oregano leaves: For herbaceous, summer flavor.
• 200g granulated sugar: Carrier for infused flavor.

For Lemon Glaze

• 1 lemon, zested and juiced: For bright, cooling finish.
• 150g icing sugar: Sweet, glossy glaze.

Instructions

Step 1: Build a Strong Sourdough Starter

(Evening—12–14 hours before mixing) Feed your mature starter so it’s vigorous by morning. In a clean jar, mix 50g mature starter + 50g flour + 50g water. Let rise at room temp (21–24°C) overnight. It should be bubbly, doubled, and smell pleasantly tangy when ready.

Why? A strong starter is key to full rise and flavor, especially in enriched dough.

Step 2: Mix and Autolyse

In the bowl of a stand mixer, combine bread flour, all-purpose flour, water, and active starter. Mix on low until a shaggy dough forms (1–2 minutes). Cover and rest (autolyse) for 30 minutes.

Why? This rest allows the flour to hydrate and gluten to begin forming naturally, leading to better extensibility.

Step 3: Add Sugar, Honey, Salt, and Butter

Add granulated sugar, honey, and fine sea salt. Mix on low until incorporated. With mixer running, gradually add softened butter in small pieces, mixing until fully absorbed and dough is smooth (5–7 minutes). Knead until you achieve a soft, elastic, slightly tacky dough.

Step 4: Bulk Fermentation

Transfer dough to a lightly oiled bowl. Cover and bulk ferment at 24–26°C for 3–4 hours, performing 3–4 sets of stretch-and-folds (every 45–60 minutes). Dough should get smoother and puff up about 50% by the end.

Master Tip: Stretch-and-folds strengthen the dough without overmixing, crucial for open, light crumb.

Step 5: Cold Proof (Retardation)

Cover the bowl tightly and refrigerate overnight (8–12 hours). This slows fermentation, deepens flavor, and firms the dough for shaping.

Step 6: Shape Donuts

Turn dough onto a lightly floured surface. Gently deflate. Roll to 1.5cm thickness. Using a 7cm round cutter, punch out donuts. Use a 2cm cutter for the center. Transfer rounds to a parchment-lined tray, cover, and proof at room temp until slightly puffy (60–90 minutes).

Why? Proper shaping and final rise ensures airy, tender donuts.

Step 7: Prepare Grilled Oregano Sugar

Meanwhile, preheat a grill pan (or outdoor grill) to medium-high. Lightly oil a grill basket or foil. Spread oregano leaves in an even layer and grill for 30 seconds–1 minute, just until fragrant and very lightly charred (do not burn!). Cool, then grind with 200g sugar in a mortar and pestle (or pulse in food processor) until sugar is green-speckled and aromatic.

Step 8: Fry the Donuts

Heat frying oil in a deep pot to 175°C. Fry 2–3 donuts at a time for 2–2.5 minutes per side, until deep golden and puffed. Drain on a rack.

Why? High-temp frying ensures a crisp exterior while the interior stays airy and tender.

Step 9: Toss in Grilled Oregano Sugar

While still warm, brush donuts lightly with neutral oil, then toss in grilled oregano sugar to coat.

Step 10: Lemon Glaze

In a bowl, whisk icing sugar, lemon zest, and enough lemon juice to make a thick, pourable glaze. Drizzle over donuts or dip half of each donut for a sunny, summery look.

Step 11: Presentation for the Office Treat

Arrange donuts in a single layer in a parchment-lined bakery box. Garnish with extra oregano leaves and lemon zest for appeal. Provide napkins to handle the sugar and glaze.

Pro Tips

• Master Your Starter: Feed and use your starter at peak activity. If sluggish, do a double feed the day before.
• Cold Proof is Essential: The overnight chill makes shaping easier and flavor more nuanced.
• Grill Oregano Lightly: Over-grilling makes herbs bitter; aim for a light char for best aroma.

Troubleshooting

Flat or Dense Donuts? Your starter may have been underactive or your kitchen too cold. Ensure strong bubbles before mixing and proof in a warm spot.

Oily or Greasy Donuts? Oil wasn’t hot enough. Always check with a thermometer (aim for 175°C) and fry in small batches.

Variations

• Matcha Sugar: Replace grilled oregano with 2 tbsp matcha powder for a vibrant green, slightly bitter coating.
• Orange Blossom Glaze: Replace lemon zest/juice with orange zest and a few drops of orange blossom water.
• Savory Twist: Skip the glaze and sugar, brush with chili oil and sprinkle flaky sea salt for a cocktail hour treat.

Storage

Best eaten the day they’re made, but will keep 1–2 days in an airtight container at room temp. For longer storage, freeze unglazed donuts and reheat briefly in a hot oven before glazing and serving.
