18. PIQUANTE SAUCE. *
CHOP, separately, six shalots, as many green gherkins, and a tablespoonful of French capers; place these in a small stewpan with a gill of French vinegar, some thyme and a bay-leaf, and a good pinch of minionette pepper; set the whole to boil on the fire till the vinegar is reduced to a third of its original quantity; then add a small ladleful of finished Espagnole sauce, and a little blond of veal; let the sauce boil gently on the side of the stove-fire to clear itself; skim it well, take out the thyme and bay-leaf, and pour it into a bain-marie for use.
