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.
