One summer our nephew, Edward, lived with us and worked on fences. He is an excellent home chef and has always been interested in cooking. One night that summer we took him to dinner at K-Paul's in New Orleans, Paul Prudhomme's restaurant. Edward loved the mashed potatoes so much he asked our waitress what the secret was and she said evaporated milk and a bit of the cooking water. Well, ever since then I have made my mashed potatoes with evaporated milk and the flavor cannot be beat.
