Makrelsalat

Every Danish child knows the smell of a madpakke. The packed lunch that travels from home to school wrapped in paper, opened at the small desk around eleven o'clock, eaten while the teacher is still talking. Inside, almost always, there is rugbrod. And on the rugbrod, often, there is makrelsalat.

This is not restaurant food and it never tries to be. Makrelsalat is what you make when you open the cupboard and find a tin of mackerel in tomato sauce and a jar of mayonnaise and decide lunch is solved. Ten minutes, maybe less, and you have something honest and deeply satisfying that has fed Danes through war years, postwar scarcity, and every ordinary weekday since. The madpakke is one of the most democratic pieces of Danish food culture. Office workers and schoolchildren eat the same thing, and nobody feels short-changed.

The technique is barely technique at all. You drain the fish, break it up with a fork, fold in mayonnaise, mustard, onion, and chives, and taste as you go. What matters is restraint. Too much mayonnaise and the fish disappears. Too little and the spread goes dry. You want the tomato sauce from the tin to still taste like itself underneath everything, the quiet backbone of the whole dish. Pay attention to the texture when you flake the fish: rough pieces, not paste. You'll know when it's right.
