Sorrel Purée
Nip the stalks off a peck of sorrel, wash well, drain, and chop up fine with one head of well-washed lettuce and a small bunch of chervil. Put all into a sauce-pan and stir over a hot fire for three minutes, then place in the oven until well dissolved. Add one and a half ounces of fresh butter, stir until it bubbles, add half a pint of good stock or beef gravy, and cook for five minutes.
