172. ESSENCE OF ASPIC-JELLY.
Put the following ingredients into a small stewpan: a few branches of green tarragon, a little chervil, a handful of chives, a bay-leaf, and sprig of thyme, minionette pepper, a blade of mace, and a little chopped raw lean of ham; moisten with a large ladleful of good consommé; set the essence to boil gently by the side of the fire for about ten minutes. Next, take it off the stove, proceed to clarify by mixing with it half the white of an egg whipped up with a spoonful of water, add a spoonful of Tarragon-vinegar, and place it on the fire to boil, whipping it with a wire whisk the while; as soon as it boils up, remove it on the side, to continue boiling gently in order to set the egg; then strain it through a napkin, and use it for braized fowls or chickens à l'Estragon or à l'Ivoire.
