Prepare six escalops as for No. 568, adding a chopped shallot, six mushrooms shred as finely as possible, one crushed clove of garlic, and a teaspoonful of chopped parsley. Moisten with a gill of Espagnole sauce (No. 151), and half a glassful of white wine. Cook for five minutes longer, pour them on a hot dish, place the escalops over, and then serve.
