Sauce Mousseline is another form of mayonnaise
very useful for soufflés glacés. To make it whip a
gill of aspic to a stiff froth, then mix into it a gill of
rich mayonnaise (any of the above will do) and a
gill of stiffly whipped cream, season with coralline
pepper, a pinch of caster sugar, and a dessert
spoonful of tarragon vinegar. Lastly, there is
Mousquetaire sauce, a delicious addition to either
dressed crab or lobster. Mince together finely a
small handful of chervil and tarragon, a few chives,
a shallot or two, and two spoonfuls of mustard; stir
it all well together, working in gradually a little salt
and pepper, then three tablespoonfuls of best salad
oil, and a dessertspoonful of good vinegar, till it is
all well blended.
