Grilled king oyster mushrooms

Step 1: Mushroom Bouillon

1. Roughly chop the onion with its skin (this will give a nice color).
2. Brown it in a saucepan with 10g butter for 5 min.
3. Add 500ml of water and some salt and pepper.
4. Add the dried mushrooms, the roughly chopped cultivated mushrooms and the coffee.
5. Leave to infuse on a low heat for 30 min, then filter.

Step 2: King Oyster Mushrooms

1. Halve the king oyster mushroom and cook it like a steak with olive oil – 5 min each side – and add salt and pepper.
2. Add a dab of butter. When the butter starts to bubble, drizzle it over the king oyster mushroom to give it a nice color.

Step 3: Plating-Up

1. Put a ladleful of mushroom bouillon in a soup dish, then place the king oyster mushroom in the center.
2. Add a little unrefined salt and serve.
