German Sauce, “Sauce Allemande.” (Cataldi.)
Used for Chicken or for Fish served in scallop shells.
Make a white roux of a little flour and a little butter cooked together. When the roux is cooked, add stock, and boil again 1 hour; reduce the sauce till it is of a proper thickness; skim most carefully the whole time; then add a liaison of 2 yolks of eggs and a little cream, which have been well stirred together; strain it again through a tammy, adding a little lemon-juice the last thing, half a lemon is enough.
