In the Prologue to the "Canterbury Tales," the Cook of London and his qualifications are thus emblazoned: "A Cook thei hadde with hem for the nones, To boylle chyknes, with the mary bones, And poudre marchaunt tart, and galyngale; Wel cowde he knowe a draugte of London ale. He cowde roste, and sethe, and broille, and frie Maken mortreux, and wel bake a pie.
