No. 715 Cotelettes de Mouton aux truffes.
Proceed with the cotelettes as before, put a pint of demi-glace (No. 9) in a stewpan, with a little consommé, and reduce till it adheres to the back of the spoon; have six middling-sized preserved truffles cut in thin slices, which throw into the sauce whilst boiling, season with a little sugar, boil all together a few minutes, glaze the cotelettes, sauce over, and serve.
