We celebrate the Feast of the Seven Fishes at my house which is my favorite holiday not because of my love of fish but because it is the one holiday where my husband spends as much time in the kitchen as I do. He is in charge of the frying which usually goes on for about two hours as my guest sit around the kitchen and consume the goodies as they come out. He does this frying on my stove top using electric fryers. My problem is this, he doesn't want the oven to be on while he is frying. I intend to cook a 7-8 pound prime rib ( for those who don't eat fish) using the high heat method before he starts frying. It seems the timing should work out under this scenario but my guests are a lovable but unruly group. How much wiggle room will i have using this method? I usually serve the cold seafood salads followed by pasta and then the main course of the prime rib and seafood dishes, so I anticipate that we will be sitting down to eat the roast about three hours after I turn the oven off. Do you think the roast will be cold or over cooked given the three hour oven resting time?
