To everything, there is a season, and—you guessed it—’tis the season for lingonberries! Jill and I are hosting our annual lingonberry party on Friday night, and we’ll be serving everyone’s favorite omega-3-rich jam along with Swedish pancakes, potato cakes, and fried herring (sounds gross, but it’s not bad!). Please arrive promptly at 8 p.m., no shoes in the house—that means you, Dan!—and you should also know that, this year, we’re making it a spouse-swapping key party. Skål!
