  • white wine 200ml
  • beef consommé or stock 400ml
  • flat mushrooms 3, finely chopped
  • shitake or cep powder a pinch
  • soy sauce 2 tsp
  • softened butter 25g 
  • egg 1, beaten


  • Step 1

    Make up the brioche mix following the packet instructions and leave it to rise.

  • Step 2

    Meanwhile, fry the onions in plenty of oil until they’re soft and translucent, about 10 minutes, they should squidge flat between your fingers when they’re ready. Turn the heat up a little and cook the onions until they’re dark reddish brown, then add the garlic and cook for a minute. Add the miso and stir, then add the wine and bring to a simmer. Add 200ml water and the beef consommé and bring back to a simmer. Cook for 20 minutes, then season with black pepper and salt, if needed. Add a splash of water if the soup is too strong.

  • Step 3

    Fry the mushroom in a little oil until it turns wet and then starts to dry out again, add the mushroom powder and 11/2 tsp soy sauce and season well. Press the brioche mix into an oblong about ½ cm thick, spread with butter, then scatter the mushroom mixture over the top, roll the dough up along the short edge and press the seam together. Cut the roll into 10-12 thick pieces and put them cut-side down on an oiled baking tray. Mix the egg with the remaining soy sauce and brush it over the top. Leave for 15 minutes.

  • Step 4

    Heat the oven to 200C/fan 180C/gas 6. Bake the brioche for 12-15 minutes, or until puffed and golden. Reheat the soup and serve it in small bowls with some brioche.
