Spelt steamed buns with hoisin aubergine are soft, lightly nutty folded buns filled with sticky roasted aubergine. White spelt flour makes the dough tender, and a 12-minute steam keeps the crumb pale.

The aubergine roasts at 220 C / 425 F while the dough proofs. The edges brown, the centers turn soft, and the hoisin glaze stays sticky.

The method stays simple. You need a bowl, a sheet pan, a skillet and a steamer. Total time is under 2 hours, and most of it is waiting.

You can steam the buns up to 3 days ahead and reheat them in 5 minutes. That suits a family dinner or a casual gathering.

Ingredient Notes

  • white spelt flour: Use white (light) spelt for a soft, pale bun. Whole spelt gives a denser bun and needs 1 to 2 tsp more water. Spelt absorbs less water than wheat flour, so measure by weight.
  • aubergine: Choose firm, glossy aubergines (eggplants) of about 300 g each. Thick-sliced king oyster mushrooms work as a substitute.
  • hoisin sauce: Brands vary in sweetness and salt, so taste the glaze before tossing. Add 1 tsp extra rice vinegar if it reads too sweet.
  • baking powder: A small amount keeps the buns light, since spelt gluten is weaker than wheat gluten. Use an aluminum-free brand if you notice a metallic taste.
  • rice vinegar: It brightens the sweet glaze. Apple cider vinegar or lime juice can replace it at the same amount.

Instructions

  1. Whisk 300 g white spelt flour, 1 tsp instant yeast, 1 tsp baking powder, 1 tbsp sugar and 1/2 tsp fine salt in a 3-quart / 2.8 L mixing bowl. Add 165 ml warm water (about 35 C / 95 F) and 1 tbsp oil, and stir into a shaggy dough.
  2. Knead on a lightly floured counter for 8 minutes, until the dough is smooth and slightly tacky. Return it to the bowl, cover, and rest for 60 minutes at room temperature, until puffy and about 1.5 times its size.
  3. While the dough rests, heat the oven to 220 C / 425 F. Toss the aubergine cubes with 2 tbsp oil and 1/4 tsp salt, then spread them in a single layer on a 33 x 46 cm / 13 x 18 inch sheet pan. Roast for 25 minutes, turning once at 12 minutes, until the edges are golden and the centers are soft.
  4. Divide the risen dough into 8 pieces of about 62 g each. Roll each into an oval about 12 x 8 cm / 5 x 3 inches, brush lightly with the remaining 1 tbsp oil, and fold in half. Set each bun on a 10 cm / 4-inch square of parchment, cover loosely, and proof for 20 minutes. Start steaming at 20 minutes even if the buns look slightly underproofed, because overproofed spelt dough sags and wrinkles in the steam.
  5. While the buns proof, whisk 4 tbsp hoisin, 1 tbsp soy sauce, 1 tbsp rice vinegar, 1 tsp toasted sesame oil, 2 minced garlic cloves, 1 tsp grated ginger and 2 tbsp water in a 26 cm / 10-inch nonstick skillet. Warm over medium heat for 1 minute, add the roasted aubergine, and toss for 2 to 3 minutes, until the glaze is sticky and coats each cube.
  6. Bring about 3 cm / 1 inch of water to a boil in a 28 cm / 11-inch wok or wide pot. Set a 26 cm / 10-inch two-tier bamboo steamer over it, with 4 buns on each tier and 3 cm between them. Cover and steam over medium-high heat for 10 minutes, then turn off the heat and keep the lid on for 2 minutes.
  7. Open each bun gently and fill with about 3 tablespoons of hoisin aubergine. Top with cucumber slices, spring onion and sesame seeds. Serve within 10 minutes.

Note

Additional Notes

  • Roast the aubergine during the first proof, so it adds no extra time to the timeline.
  • Start steaming at the 20-minute mark of the second proof, even if the buns look slightly underproofed.
  • Taste the glaze before tossing, since hoisin brands vary in saltiness.
  • Check the hoisin label to confirm it is vegan.

Equipment

  • 26 cm / 10-inch two-tier bamboo steamer
  • 28 cm / 11-inch wok or wide pot
  • 33 x 46 cm / 13 x 18 inch sheet pan
  • 26 cm / 10-inch nonstick skillet
  • 3-quart / 2.8 L mixing bowl
  • rolling pin

Tips

  • Use white spelt flour and measure by weight, because spelt dough that is too wet turns sticky and tears when you fold it.
  • Spread the aubergine in a single layer on the sheet pan, with a little space between cubes, for browned edges.
  • Brush each dough oval lightly with oil before folding, so the finished bun opens cleanly without tearing.
  • Set each bun on its own 10 cm / 4-inch square of parchment and leave 3 cm between buns in the steamer.
  • Fill the buns just before serving and eat within 10 minutes, so the bun stays soft and the filling stays glossy.

Variations

  • Swap the aubergine for thick slices of king oyster mushroom, roasted until browned and tender, for a meatier bite.
  • Add 1 tablespoon of chili crisp or a pinch of chili flakes to the hoisin glaze for a gentle heat.
  • Add quick-pickled carrot or red cabbage to each bun for acidity and crunch, which balances the sweet glaze.

Storage and Reheating

Steamed spelt buns keep in an airtight container in the refrigerator for 3 days. Let them cool completely first, so condensation doesn't make the tops sticky. Store the hoisin aubergine separately for up to 4 days.

Reheat the buns in a steamer for 5 minutes from the refrigerator, or 8 minutes from frozen. Warm the aubergine in a 26 cm / 10-inch skillet over medium heat for 3 minutes, with a splash of water if the glaze has tightened.

Freeze unfilled buns in a single layer, then bag them for up to 2 months. No thawing is needed before steaming. Fill them only after reheating.

Serving Suggestions

Fill each warm bun with about 3 tablespoons of hoisin aubergine, a few cucumber slices, sliced spring onion and sesame seeds. Serve two buns per person for a light dinner.

Put the toppings and a small bowl of chili sauce on the table, so everyone fills their own. The bun stays soft and the filling stays glossy when you eat within 10 minutes.

Miso soup or steamed bok choy rounds out the meal. Leftover aubergine also works spooned over rice the next day.

Frequently Asked Questions

Expand All:

Why are my spelt steamed buns wrinkled or collapsed after steaming?

Overproofed dough is the usual cause. Spelt gluten is weaker than wheat gluten, so buns left past the 20-minute second proof sag in the steam. Steam for 10 minutes, then turn off the heat and keep the lid on for 2 minutes before lifting it.

Can I use whole spelt flour instead of white spelt flour in steamed buns?

Yes, but the buns come out denser and darker. For a softer result, use 150 g whole spelt and 150 g white spelt. Add 1 to 2 teaspoons more water, because the bran absorbs extra liquid, and expect a slightly nutty flavor.

Can I freeze spelt steamed buns before filling them?

Yes. Steam the buns, cool them fully on a rack, then freeze in a single layer before bagging them. They keep for up to 2 months. Frozen buns need no thawing. Steam from frozen for 8 minutes, then fill with warm hoisin aubergine.

What goes well with hoisin aubergine steamed buns?

A bowl of miso soup keeps the meal light, and steamed bok choy or edamame adds protein and color. A quick cucumber salad dressed with rice vinegar adds crunch. Two buns per person make a modest dinner on their own. Serve them with plain rice if you want a larger meal.

Are spelt steamed buns with hoisin aubergine vegan?

Yes, the dough and the filling use no dairy, eggs, or animal fats. Check the hoisin label to confirm, since recipes vary by brand. The buns are not gluten-free, because spelt is a type of wheat and contains gluten. Hoisin sauces often contain wheat as well.

What is the difference between these buns and gua bao?

Gua bao is the Taiwanese folded bun, usually filled with braised pork belly. These buns use the same open, folded shape, but the dough is made with white spelt flour and the filling is oven-roasted hoisin aubergine. Spelt adds a mild nutty flavor, and the crumb stays soft rather than chewy.
