Crisp Fish Fingers with Tartar Sauce

TO MAKE TARTAR SAUCE: Remove yolks from the hard-boiled eggs and press them through a sieve into a mixing bowl. Add the raw egg yolk and seasonings and beat until smooth. Slowly add the vegetable oil, whisking briskly, to make an emulsion in the same way as mayonnaise.

From time to time add a few drops of the vinegar. When done, stir in the remaining ingredients. Spoon into a small serving dish.

TO MAKE FISH FINGERS: Cut the fish diagonally across the fillets into pieces 3/4 in (2 cm) wide. Mix flour, salt and pepper together. Dip each piece of fish into the seasoned flour, then into the beaten egg and finally into the bread crumbs to coat evenly. Chill for 30 minutes. Heat the deep-frying oil and fry the fish, no more than 5-6 pieces at a time, until crisp and golden. Drain on a rack covered with paper towels and serve hot with the sauce and wedges of lemon.
