Andy's Prime Sauce for a Crowd

The now-defunct Andy's Diner, a South Seattle landmark for more than 50 years, was famous for its barbecued steak. The restaurant, housed in a collection of historic railroad cars, served its last barbecued steak and bourbon on the rocks in 2008. The rail cars include one that President Franklin Roosevelt reportedly traveled in during his 1944 re-election campaign. Posted in response to a recipe request. Cooking time approximate
