We just checked the official Thanksgiving Rule Book, and in Article 1, Line 3, it clearly states, “Sweet potatoes must be included on the table in order to qualify as a true Thanksgiving feast.” This detailed book covers all the basics: Must have at least one type of stuffing. Each slice of pumpkin pie shall be topped with a dollop of whipped cream. Omitting the green bean casserole is forbidden and will incur penalties. There is also a great section on how to say the appropriate thing when giving thanks, as well as informative chapters on how to deal with drunken relatives. Everything is covered here: from how to quickly and smoothly change the conversation topic from politics to funny youtube videos, to tips on being polite if the turkey happens to be dry. This delicious recipe has been a tradition in Ryan’s family for over 40 years, and Thanksgiving truly wouldn’t be the same without it. And according to the official Rule Book, this dish qualifies as the perfect sweet potato casserole: filled with tender sweet potatoes tossed with fresh ripe cranberries, covered with a cinnamon and brown sugar oat crumble, and baked until the cranberries soften and burst, releasing their ruby-colored juice, which bubbles under the crisp, crunchy warmly-spiced topping.
