Because there is no happier food than a deviled egg. Because chipotle peppers--that is, smoked jalapenos canned in fiery barbecue sauce called adobo--taste so good with egg, Cheddar, and chives. And because I need to share with you this crucial technique: the moment you're done boiling your eggs, plunge them into an ice bath. This prevents that ugly, moldy-looking green edge you otherwise often get around the yolks. Eggcellent.
Put the eggs in a saucepan, cover with cold water by 1 inch, and bring to a boil over high heat. Reduce the heat and simmer for 10 minutes; then drain and immediately plunge the eggs into an ice bath to cool.
Peel the eggs, slice in half lengthwise, and scoop out the yolks. Put the whites on a platter. Pass the yolks through a sieve into a medium bowl, or just mash with a fork. Mix in the cheese, mayo, sour cream, chives (reserving 1 teaspoon for garnish), chipotles, paprika, and salt.
Use a pastry bag fitted with a 1/2-inch tip to pipe the filling into the whites, or, if you're less fancy, use 2 spoons. Sprinkle with the reserved chives. Cover loosely with plastic wrap and refrigerate until serving, which should be within a day.
