Step 1:
Brush the sea biscuits with salt, dip in water with vinegar and salt for a few seconds, and pat dry excess water. Set aside.
Step 2:
Cook the vegetables whole and separately, except for the artichokes. Remove from fire and cool. Peel and slice the beets and potatoes; dice the rest of the vegetables. Slice and cook the artichokes. When done, remove from heat and cool. Dress all the vegetables separately with oil, vinegar and salt. Set aside.
Step 3:
Poach, bone, and crumble the bass and dress with oil, lemon and salt. Do the same with the lobster and set aside.
Step 4:
Poach the prawns and set aside. Hard boil the eggs, cool and quarter. Make 12 skewers alternating 2 olives, 2 shrimps, 2 anchovy fillets. Set aside.
Slice the air-dried fish very thinly. Mix the capers and the mushrooms separately. Oen the oysters and shell them. Set all the ingredients aside separately.
Step 5 - Topping Sauce:
Place all the ingredients into a food processor, mix well to get a fluid consistency. Set aside.
Step 6 - Preparation and Presentation:
Take a large round or oval platter and start with the sea biscuits flat on the platter. Sprinkle with olive oil; add a few thin slices of air-dried fish and dress with a 2-3 tbs. of the sauce.
Next, carry on layering all ingredients taking a little bit of each at a time, placing the vegetables first, then the fish, the capers and the mushrooms. Add some sauce on each layer and carry on until all ingredients are used. As you build up, the final shape should be like that of a dome or a pyramid.
Top the whole with sauce and decorate with the skewers previously prepared. Circle the base of the mold with oysters topped with green sauce and serve.
