Mousse: Savoury (Ham Mousse / Chicken Liver Mousse)

The classical cold mouse savoury preparations appear throughout Escoffier and are a fundamental element of the cold buffet table — the buffet froid that was the showpiece of the grand hotel kitchen. Ham mousse, chicken liver mousse, foie gras mousse, salmon mousse — each built on the same foundation technique, differing only in the nature of the protein and its preparation before incorporation.

A cold savoury preparation of puréed protein lightened by whipped cream and set with gelatin — yielding a texture that is simultaneously airy and rich, that unmoulds cleanly and slices precisely, and that delivers the flavour of its main ingredient with a concentration that raw or simply cooked preparations rarely achieve. Savoury mousse is the cold side of the charcuterie discipline: it requires the same consideration of seasoning, texture, and presentation as a terrine, but achieves a completely different result in both texture and occasion.

As Segnit notes, ham and cream is a pairing of chemical compatibility — the lactic fat of the cream carries the Maillard compounds of the cured, cooked ham (the specific pyrazines and sulphur-containing Maillard products of cured pork) and amplifies them on the palate. Cold suppresses both the salt and the fat-carried aromatics simultaneously — which is why correctly seasoning a cold preparation at room temperature is not caution but chemistry.
