can’t tell you exactly where this dish came from — only that it’s the star of my family’s Christmas Eve Feast of the Seven Fishes meal. I only make it once a year, which makes its briny, garlicky, umami-packed flavor so special to me (and something I look forward to every year). But the dish is quick and dead simple, and chances are you have all the ingredients on hand. So if you’d like to make this spaghetti laced with red pepper flakes, garlic, anchovies, and black olives one of your weeknight staples, well, I can’t fault you for that.
