Tips from the kitchen

  • Let the potatoes steam dry for a few minutes after draining. If they go into the dressing while still wet, the crème fraîche thins out and you lose that coating effect.
  • Taste the dressing before you toss anything. Horseradish varies a lot in heat depending on how fresh it is, so you might want more or less than the tablespoon called for.
  • The mackerel breaks up more than you expect once it hits the warm potatoes and gets folded in. Keep the pieces on the larger side when you break them up, so you still get proper flakes in the finished salad.
  • Add the salad leaves last, right before serving. They wilt fast against warm potatoes, and you want some texture left when it hits the table.

Ways to vary it

  • Smoked trout works well here instead of mackerel. It's milder, so the horseradish dressing comes through a bit more.
  • A few capers scattered over the top add a briny hit that goes well with the fish and the sharp dressing. Completely optional, but worth trying if you have them.
  • For a more substantial plate, slice a soft-boiled egg over each portion. The yolk mixes into the dressing and makes the whole thing feel a bit richer.

Storage & leftovers

This salad doesn't keep well once assembled. The leaves wilt and the potatoes absorb the dressing overnight, so it's best eaten the same day. If you want to get ahead, keep the dressing, potatoes, and toppings separate in the fridge and put it together just before eating.

What to serve with it

A cold glass of dry white wine or sparkling water with lemon sits well alongside this. Some crusty bread on the side is good too if you want to mop up the dressing.
