Wash and rinse the romaine hearts. Pat dry. Lay out a 6 inch piece of Saran wrap. Place the Dover sole filet flat on the saran wrap, season with salt and pepper. Lay the nori sheet on top of the fish filet. Arrange the scallops down the middle of the Sole filet.
Gently roll the the Filet over the scallops and tie the ends of the saran wrap. Wrap with aluminium foil and tighten the roll by twisting the foil at the ends in opposite directions. Slice through the foil and fish cylinder into 2 inch thick rolls.
In a frying pan heat up the olive oil and add a tsp of butter. Remove the foil and saran wrap from the outer edge of the fish roll and place face side down in the hot pan. Sear for one minute and flip. Place in the oven for seven minutes at 350 degrees Fahrenheit.
While the fish is cooking, in a separate frying pan heat up the fish stock and poach the romaine heart in it for the duration of the fish cooking time.
Saffron shallot cream sauce
Heat up the canola oil in a small sauce pan. Add the shallots and sweat them until translucent. Add the peppercorns and deglaze with the white wine. Add the fish stock and the saffron. Reduce by two thirds. Add the cream and reduce by two thirds. The sauce should be thick so it does not run on the plate.
Plate Assembly:
Remove the romaine heart from the poaching liquid and place in the centre of the plate. Arrange the sole rolls on top of the poached romaine heart. Add some deep fried celery root as garnish. Drizzle sauce on plate with artistic flare.
