Wild Mushroom and Truffle Dumplings

This luxurious fusion mandoo has been one of the most popular dumplings on the menu at my restaurants. The mushroom duxelle goes beautifully well with dwengjang, heightening the umami hits on all levels. Vegetarians and meat eaters alike love this little bundle of flavour.

Ingredients

Makes about 45 dumplings

  • 50 thin, round eggless wonton wrappers, 10cm (4in) diameter

HERB OIL

  • 100ml (3.fl oz) extra virgin olive oil
  • 10g (1/4 oz) thyme, washed and dried
  • 10g (1.4 oz) oregano, washed and dried
  • 10g (1/4 oz) rosemary, washed and dried

TRUFFLE DIPPING SAUCE

  • 180ml (6.fl oz) soy sauce
  • 1 tbsp black truffle paste
  • 3 tbsp black truffle oil
  • 2. tbsp lemon juice
  • 2 tbsp yuja (yuzu) juice
  • 2 tbsp mirin
  • 2 tsp rice wine vinegar
  • 2. tsp caster sugar

FILLING

  • 2 garlic cloves, grated or finely chopped
  • 1/2 small onion, finely diced
  • 350g (12oz) shiitake mushrooms, stems removed and roughly sliced
  • 350g (12oz) shimeji mushrooms, stems removed and roughly sliced
  • 350g (12oz) portobello mushrooms, caps peeled, stems removed and roughly sliced
  • 85g (3oz) dwengjang (Korean soy bean paste)
  • 85g (3oz) unsalted butter, at room temperature
  • 2 tsp porcini powder
  • 40g (1.5 oz) black truffle paste
  • 35g (1.25 oz) chives, finely chopped
  • sea salt and freshly ground black pepper

Method

For the herb oil, in a medium deep pan, slowly and gently heat the olive oil and add the herbs. Remove from the heat and leave it to steep for 30 minutes. (The longer the oil sits with the herbs, the stronger the flavour will be.) Meanwhile, to make the truffle dipping sauce, whisk together all the ingredients in a small bowl.

Remove the herbs from the steeping oil then heat the oil over a medium heat. Add the garlic and onion and cook until softened, stirring often. Add the mushrooms and dwengjang and cook, stirring occasionally, for 15–20 minutes, or until the mixture becomes dry. Remove from the heat and stir in the soft butter. Chop the mushroom mixture into small pieces using a food processor (or by hand into 5mm/ 1/4 in pieces). Set aside to cool, then add the porcini powder, truffle paste and chives and mix well. Season with salt and pepper.

For the dumplings, fill a small bowl with water. Working with one wrapper at a time on a clean surface, spoon 25g (1oz) of the filling into the centre of the wrapper. Dip a forefinger in the water and run it along the edges of the wrapper to moisten. Fold the wrapper in half away from you. Starting at the top of the half circle and working towards the ends, press firmly together to seal, pressing out any air bubbles. Take the pointy ends of the half circle and pull them together, folding them downwards and towards each other so they overlap slightly and form a shape that resembles a nurse’s cap. Dab the place where the ends meet with a little water and pinch together to seal. Lay the dumplings in a steamer basket, leaving at least 2.5cm (1in) of space between the dumplings, as they will expand when cooked. (Cook the dumplings in batches, if needed.)

To cook, bring the water in the steamer base to a steady simmer. Set the steamer basket over the water, cover and steam the dumplings for 7 minutes, or until cooked through. Repeat with the remaining dumplings, if needed. Serve immediately with the dipping sauce.

@judyjoochef Instagram profile imageWhen the former Prime Minister Rishi Sunak @rishisunakmp gives you a shoutout… 😳

A couple years ago, my team and I had the honor of cooking at No. 10 Downing Street during the Korean state visit — we gave British classics a bold Korean makeover with gochujang, ssamjang, and of course, kimchi 🇰🇷🇬🇧

To hear Rishi Sunak mention it at the Asian Leadership Conference — and say his daughters still talk about the food — is beyond humbling. That’s the magic of sharing culture through food.... food diplomacy!

Massive thanks to the incredible team who made it all happen 💛

@judyjoochef Instagram profile imageEvery time I see a Seoul Bird stand in full swing, I’m overwhelmed with gratitude — and our spot at Tottenham Hotspur Stadium was no exception. Serving up Korean fried chicken to thousands of hungry fans during the Beyoncé concert? A total “pinch me” moment. 🍗🐝✨

I used to hide my school lunches in embarrassment, hoping no one would catch a whiff of kimchi. Now? Those same flavors are center stage — devoured by the BeyHive in one of London’s most iconic arenas.

Huge thanks to the incredible @tottenhamhotspurstadium team led by @regionallondonchef and every fan who came hungry — from the stands to Club Renaissance. 💛

And of course, to the unstoppable @seoulbirduk crew and the amazing @chefandrewhales — thank you for bringing the flavor and the Seoul every single day.

@judyjoochef Instagram profile imageLondon, you really brought the heat this past weekend! 🔥🇰🇷

Had an absolute blast teaching at the K-Food BBQ Cook School at @tasteoflondon — it was such a joy to share the bold and totally addictive flavors of Korean BBQ with so many hungry (and K-BBQ-loving!) Londoners.

I served up one of my all-time favorites: Korean marinated beef short ribs — galbi, of course! 🥩✨

I even had the honor of meeting Korea’s Ambassador to the UK, Yoon Yeocheol — a proud moment made even better by the scent of char grilling meat in the air.

Huge thanks to everyone who came through to cook, taste, and celebrate Korean food with me — and to the brilliant @julian_d_brown_chef for bringing the BBQ magic alongside me! This is what I call BBQ with Seoul. ❤️

Big thanks to our friends at @koreafoodsuk for making it all happen, and to @hexclad_europe and @firemadeuk for keeping the setup sharp and the flames steady 🔥

You can even find the recipe in K-Quick, my latest cookbook 📚@quartobooksuk @quartobooksus @whitelionpublishing5 days ago via Instagram
@judyjoochef Instagram profile imageDinner at @losmochislondon LUNA—an intimate omakase-style chef’s table—was an absolute knockout. Think fiery fiestas and delicate umami whispers, all artfully plated under the glow of moonlight. 🇲🇽✨🇯🇵 And the best part? It’s all helmed by the brilliant Chef Leo, who is Filipino. I adore this beautiful collision of cultures—it’s fusion with soul.

Chef Leo @chef_leonard1 has crafted something truly transportive, with the moon as his muse (hence the name). Each course arrived with elegance, flair, and a little theatrical sparkle. The wagyu katsu sando? Pure decadence—meltingly tender, rich with flavor, and gone far too quickly. And that tuna and caviar dish? Let’s just say I didn’t leave a single glistening pearl behind. 

We ended on a high note: a soufflé crowned with a scoop of fresh wasabi ice cream. A little heat, a little sweet—chef’s kiss.

Huge thanks to the stellar team for a night that dazzled from start to finish. Already plotting my return orbit…
