PREPARATION

SOLE
Fillet the soles and set aside. Wrap the Jerusalem artichokes in aluminium foil and oven roast at 180°C for approximately 40 minutes, until done. Remove the foil, make a slit on top and squeeze to extract the pulp. Retain the peel and dry it at 60°C. Set aside. Transfer the pulp to the Thermomix, add 50 cc of cream for every 200 g of pulp, process, then strain. Transfer to a 1-charger siphon and reserve in a 50°C bain-marie.

Brunoise-cut the shallot. Mince the chives. Brunoise-cut the mushroom stems. Add the shallot to a heat hot suaté pan with olive oil, then add and brown the mushrooms. Remove from heat, season with salt and add the chives. Set aside.

Cut two slices of mushroom and dust with the mushroom powder. Dry at room temperature. Cook the sole for 5 minutes in a 70°C combi oven at 30% humidity. Matching up the edges, lay one dorsal fillet atop the lower fillet.
Toast the hazelnut in butter in a saucepan until the butter is browned (noisette).
Fry the Jerusalem artichoke in 180°C sunflower oil.

LIME GEL
Mix the lime juice and agar-agar in a saucepan, bring to a boil and whisk for 2 minutes. Once the mixture has cooled, process in a blender until it has a gel-like consistency. Transfer to a squeeze bottle.

PLATING
Set a base of sautéed mushrooms on a plate and, on top, arrange the sole, two dots of Jerusalem artichoke foam, some of the crisped Jerusalem artichoke, beurre noisette and hazelnuts atop the sole, mushroom slices and black truffle slices. Finish with two dots of lime gel and pimpernel leaves.
