Preparation of Scallop / Celery / Watercress / Caviar
Scallop:
Fry one scallop each (at least 50 g), separated from the shell, lightly salted in a hot pan with rapeseed oil for approx. 2 minutes.
Flour the corail (roe of the scallop) and also fry briefly.
Watercress- and celeriac-puree:
Cook the celeriac in a steamer at 85 °C until soft and squeeze out all the juice. Meanwhile, blanch the lettuce, baby spinach and watercress in boiling salted water for about a minute, then rinse in ice water. Squeeze the lettuce very well. Purée the warm celeriac in the Thermomix with the lettuce and cold butter until smooth. Pass the purée through a sieve and season to taste with salt and pepper.
If the purée is not fine enough, place it in a pacotizing beaker and freeze. Pacotise the purée and then blend again in the Thermomix with a little xanthan gum to the optimum consistency.
Salt dough:
Mix all the ingredients for the salt dough together.
Cut the celery stalks into 3 mm slices. Cook in the salt dough at 220 °C until the core temperature reaches 92 °C.
Confit of celery:
Peel the celery stalks and remove the fibres.
Vacuum the celery stalks together with nut butter and salt and cook at 85 °C for 10 m.
Pickled watercress stalks:
Bring all the ingredients to the boil.
Allow the stock to cool down, vacuum-pack the stalks together with the stock and leave to infuse for 4–5 days.
Watercress oil
Heat all the ingredients together in the Thermomix to 80 degrees, pour into a micro sieve and cool in a bowl on ice.
Leave the cold oil to hang in a piping bag for several hours so that the cloudy substances settle and the pure green oil is created.
Beurre Blanc
Sauté the shallots in butter, deglaze with white wine and verjus. Reduce the white wine completely.
Add the fish stock, bring to the boil and blend with the cold butter. Do not heat the thickened beurre blanc above 60 °C.
Finally, add the trout roe, char roe and watercress oil.
Serving & decorating
Using a peeler, shave approx. 8 cm long ribbons off the celeriac and lightly salt it.
Once all the components have been prepared, they can be served together with 3 celery leaves and 3 watercress leaves (lightly salted) and 10 g Royal Premium Caviar.
