The Gastronomic Regenerator: A Simplified and Entirely New System of Cookery: With Nearly Two Thousand Practical Receipts Suited to the Income of All Classes

a pound of cooked ham, twenty button mushrooms, and six middling-sized French truffles; then put a teaspoonful of chopped eschalot in a stewpan, with a teaspoonful of salad oil; fry them of a light yellow colour, add a quarter of a tablespoonful of flour (mix well), half a pint of stock, and a pint of white sauce; let it boil, keeping it stirred, add your meat and the other ingredients, season with pepper and salt, and when boiling add the yolks of two eggs; stir them in quickly, and pour the whole into the place you cut the shoulder from; egg it over with a paste-brush, sprinkle bread-crumbs and grated Parmesan cheese over, brown it lightly with the salamander, dress upon your dish, pour a sauce bechamel à la crème (No. 56), rather thin, round and serve. No. 496. _Leg of Lamb à la St. John._ Roast the leg in vegetables as described (see No. 417); an hour and a half would be sufficient; when done, place a paper frill on the knuckle, and lay it in your dish; have ready prepared the following sauce: put the yolks of three eggs in a stewpan, with half a pound of fresh butter, the juice of half a lemon, a little pepper, salt, and two tablespoonfuls of tarragon vinegar; place it over a moderate fire, keeping it stirred with a wooden spoon, and when the butter has melted and begins to thicken (great care must be taken that the eggs do not curdle, which they will do if you allow it to get too hot before the butter is melted, or allow it to boil in the least), add a pint of white sauce (No. 7), and a little sugar; mix all well together, pass through a tammie into a clean stewpan, place again over the fire to get hot (but not to boil), keeping it stirred; add half a gill of cream, and if too thick a little milk, pour it over the lamb, have ready a few pistachios each cut in eight lengthwise, sprinkle over, and serve very hot. No.
