No. 503 Leg of Pork sauce Robert.
Score the skin of the leg with a sharp knife, oil some paper, wrap the leg up in it, and roast about two hours and a half of a nice yellow colour; have ready the following sauce: put four tablespoonfuls of chopped onions into a stewpan, with two ounces of butter, stir over a moderate fire till the onions are nicely browned, then add three tablespoonfuls of tarragon vinegar (let it boil), a quart of brown sauce (No. 1), half a pint of consommé, and a little brown gravy; let it boil at the corner of the stove about twenty minutes, skim it well, reduce it till it adheres to the spoon, season with a little cayenne pepper, salt, and two tablespoonfuls of French mustard; when ready to serve add twenty small gherkins, twenty pickled mushrooms, twenty small quenelles (No. 120), pour the sauce in the dish, dress the leg upon it, put a paper frill on the knuckle and serve.
