Clapotons

Clapotons belongs to the thrifty offal cookery of Lyon, a city whose bouchon tradition grew out of using every cheap and humble cut — trotters, tripe, head, blood — that the silk-workers and market porters could afford. Sheep's-trotter salads of this kind are part of the old Lyonnais and broader French repertoire of pieds (feet) dishes, alongside the better-known pieds de mouton poulette and the pieds et paquets of Provence; the name clapotons is the local Lyon term. It has no documented inventor and survives as a traditional bouchon dish rather than a restaurant creation, increasingly scarce as offal fell out of everyday fashion.

Sheep's trotters are nearly all skin, tendon and gelatin, so the cooked meat is soft, sticky and yielding, with a faint muttony savour and a texture that clings to the lips — the signature mouthfeel of well-cooked feet. The vinaigrette is the counterweight: sharp with vinegar and mustard, loud with raw shallot and parsley, cutting cleanly through the richness. Eaten cold the gelatin firms up and the salad sets slightly; warm, it is looser and more unctuous. It is an acquired, honest taste — gluey and tangy, frankly offaly — and a few cornichons or a slice of good bread round it out.

The whole dish hangs on long, slow simmering. Trotters are packed with collagen and almost no muscle, and only hours of gentle cooking in an aromatic court-bouillon will hydrolyse that collagen into gelatin — the point at which the meat turns tender and the bones can be pulled clear. Cooked too briefly the trotters stay rubbery and stubborn on the bone. Because they are so gelatinous, the cooled meat sets to a soft aspic-like firmness, which is why clapotons holds its shape as a cold salad. The acidic vinaigrette does double duty: it brightens and balances the heavy gelatin and fat, and dressing the warm trotters lets them absorb the seasoning before they set.
