2 cans of sweet potatoes (AKA (incorrectly) "yams")
1 cup brown sugar
1 teaspoon cinnamon
1/2 teaspoon nutmeg
2 whole cloves
2 bags of mini-marshmallows

1) Eat half a bag of marshmallows before the turkey is even put on. Moral support often comes in the form of fluffy high fructose corn syrup.

2) Put the yams, brown sugar, cinnamon, nutmeg, and cloves in a large pan, and put the lid on. Heat to boiling, and let it boil for ~15 minutes.

3) Dump in most of the remaining half-bag of marshmallows on top of the yams and recover with the lid (NOT the pumpkin pie!), to let the marshmallows melt.

4) Forget the existence of said yams for about 10 minutes. (Length of time is dependant on one's personal ability to keep track of five other dishes at once, while coordinating finding Stuff to eat food with, as well as Convenient Memory amount vs normal operating RAM).

5) Re-discover the yams, and upon taking lid off, discover that all the marshmallows have melted into nothingness, and add the remaining handful of marshmallows from the open bag on top, and immediately move pan to table (not forgetting to turn off the stove eye). By the time all plates, forks, spoons, food, chairs, and people have been located and put near/on/by the table, the marshmallows will have melted into a nice fluffy patchwork layer on top of the yams.

6) After Thanksgiving Dinner has been worn off by watching The Big Game or other, similar, high-energy activties (computers games, movies, marathon-napping), the second bag of marshmallows is one's treat for leaving a whole half-bag of marshmallows uneaten in the first place.
