Here's a simple recipe from an Aunt of mine who's living in Florida:

Yankee Pork Roast:

1. Take one blue collar Yankee, plump and pale, and reserve a room at the Holiday Inn Orlando
2. Put Yankee on a bus. Fill it with other Yankees so that, in case of catastrophe, no space is wasted.

3. Prepare marinade of fruit juices and cheap wine. Chill.
4. Remove outer layer of polyester from Yankee and place on rack near a large, reflective body of water.
5. Coat generously with coconut oil and allow to broil

This is a relatively simple recipe, as the Yankee will turn itself periodically, keep itself soaked in alcohol, and make its own gravy, which can be wrung from the towel.

Of course, Yankee pork roast is inedible, but when it goes back where it came from (and getting them to leave can sometimes be tricky), its beet-red color will discourage other Yankees from straying from their side of the Mason-Dixon.
