Boil potatoes in heavily salted water until tender (12-15 minutes), drain, cool, peel, thinly slice and set aside.
Fillet skate by removing the top and bottom fillets from the bone with a knife. Refrigerate fillets until required. Combine bones in a large saucepan with just enough cold water to cover, simmer over low heat until well-flavoured (30 minutes). Strain through a fine sieve into a clean pan (discard bones), then return to the simmer. Season to taste, then add skate fillets, one at a time, and poach until just opaque (2-3 minutes), set aside. Simmer poaching liquid over medium heat until reduced by half (20-30 minutes), set aside.
Meanwhile, combine shallot, cornichon, parsley and mustard in a bowl, season to taste and set aside.
Lightly grease a 1.5-litre terrine mould with oil, then line with plastic wrap, allowing plastic wrap to overhang. Place an even layer of skate in base of terrine, add an even layer of potato slices, slightly overlapping, season to taste, then scatter with half the shallot mixture. Add 60-80ml poaching liquid (just enough to keep wet). Repeat to fill terrine, cover with plastic wrap, weight with food cans and refrigerate until chilled and firm (6 hours-overnight). Just before serving, invert terrine onto a board, remove plastic wrap, then thickly slice.
Meanwhile, for garlic mayonnaise, whisk yolks, vinegar and garlic in a bowl until yolks turn pale. While whisking continuously, gradually add oil, starting with one drop at a time, then in a thin stream until thick and emulsified. Season to taste and refrigerate until required. Makes 700ml.
For parsley salad, combine shallot, lemon juice, oil and a pinch each of sea salt and freshly ground black pepper in a bowl to marinate (3-5 minutes). Add parsley and season to taste with lemon juice, oil and sea salt. Toss lightly and serve with sliced skate and potato terrine and garlic mayonnaise.
