Every year, I make a sweet-potato puff for Thanksgiving; it's a family favorite, the "it wouldn't be Thanksgiving without it" side dish.
Every year, I follow the recipe with a few slight alterations (all cinnamon instead of part nutmeg, doubled, with marshmallows instead of the sugary praline topping). Every year I make it the day before because the need to boil the sweet potatoes ahead of time seems to make it easier to get it out of the way before the main cooking event.
Every year I carefully double the amount of butter and add it to the orange gloppy mixture whirling away in the mixer.
And every year I forget what happened the previous year, when the cold sticks of butter coat themselves with sweet potato and hit into the beater.
So every year I clean up random glops of orange sweet potato from my stove, my floor, my shirt...
...and think "Man, I forgot to melt the butter again."
Every single year.
At least my "company" are out shopping with my husband and daughters. Because every single year, I also forget that some of the marshmallows in the cabinet are supposed to be for Thanksgiving, and let the girls use them up in hot chocolate two weeks before.
