Bagt Havorred med Dildsmor og Nye Kartofler

Ingredients

Equipment Needed

• •Large roasting tin or baking tray, big enough for the whole fish
• •Baking parchment
• •Sharp kitchen knife
• •Medium saucepan for the potatoes
• •Instant-read thermometer (optional but helpful)

Instructions

1. 1

   Make the dildsmor

   In a bowl, work the softened butter with a fork until it's smooth and pliable. Add the finely chopped dill (use a generous handful from one of your bunches), the lemon zest, lemon juice, and a good pinch of flaky sea salt. Mix until everything is evenly distributed and the butter is green-flecked and fragrant. Spoon the butter onto a piece of baking parchment and shape it into a rough log, about 4cm across. Roll the parchment around it, twist the ends, and chill in the fridge until firm. The butter needs to be cold when it reaches the table so it melts slowly over the hot fish, releasing the dill and lemon in waves rather than all at once.

   Use more dill than you think. The butter absorbs the flavor, and what seems like too much in the bowl becomes exactly right when it melts on the plate.

   Prepare the trout

   Heat your oven to 200C. Rinse the trout under cold water and pat it completely dry inside and out with kitchen paper. Moisture on the skin prevents it from crisping, so take your time with this step. With a sharp knife, score the skin on each side: three or four diagonal cuts, about 1cm deep, spaced evenly along the body. These cuts aren't decoration. They let the heat reach the thickest part of the flesh evenly and allow the butter to seep into the fish as it bakes. Season the cavity and the scored skin generously with fine sea salt and white pepper. Lay lemon slices inside the cavity in a single overlapping row, then pack in a generous handful of dill sprigs. The aromatics perfume the fish from within, and the lemon juice steams gently as the fish cooks, keeping the flesh moist.

   White pepper, not black. Black pepper leaves dark specks on the pale flesh and tastes too sharp against the delicate fat of the trout. White pepper does its work quietly.

   Bake the trout

   Line a large roasting tin with baking parchment and brush it lightly with the rapeseed oil. Lay the trout on the parchment and scatter the cold butter pieces over the scored skin. The butter must be cold so it melts slowly as the oven heats, basting the skin gradually rather than pooling and burning. Slide the tin into the middle of the oven and bake for 25 to 30 minutes. A 1.5kg fish takes about 25 minutes. You'll know it's done when the skin has turned golden and taut, the butter on the surface is nutty and foaming, and the flesh at the thickest point behind the head has turned from translucent to opaque. If you have an instant thermometer, 55C at the center is what you want. The fish will carry over a few degrees as it rests.

   Don't open the oven for the first twenty minutes. Every time you open the door you lose heat, and the skin needs consistent high temperature to crisp properly. Trust the oven. Trust the fish.

   Cook the nye kartofler

   While the trout bakes, scrub the nye kartofler gently under cold water. Don't peel them. The skins of new potatoes are thin, tender, and full of the earthy sweetness that makes nye kartofler worth waiting all year for. Place them in a pot of cold, well-salted water and bring to a steady boil. Starting in cold water is important: it lets the potatoes heat through evenly from the outside in. If you drop them into boiling water, the outsides cook faster than the centers and you end up with potatoes that are floury on the edges and hard in the middle. Cook for 15 to 18 minutes, depending on their size. They're done when a thin knife slides through the center with no resistance at all. Drain them well, return them to the warm pot, and toss gently with the butter and a few torn dill sprigs. The season decides what's on the table, and in June, nothing belongs beside a baked fish more than these.

   Rest and serve

   When the trout comes out of the oven, let it rest on the platter for five minutes. This is not optional. The flesh is still cooking gently from residual heat, and the juices, which have been pushed to the surface by the oven's intensity, need time to redistribute back through the fish. If you cut in immediately, those juices run out onto the platter instead of staying in the flesh where they belong. After five minutes, scatter fresh dill fronds over the top and arrange lemon wedges around the fish. Bring the whole platter to the table alongside the bowl of nye kartofler and the dildsmor, sliced into thick rounds straight from the fridge. Let people help themselves. A thick slice of cold dildsmor on a piece of hot fish, a few nye kartofler on the side, a squeeze of lemon. That's the whole meal. Cooked with love. Tak for mad.

Chef Tips

• •Buy the trout whole and ask the fishmonger to clean and scale it for you. A whole fish bakes more evenly than fillets, and the bones keep the flesh moist. If you can only find fillets, reduce the baking time to 15 to 18 minutes and watch closely. Fillets forgive less.
• •Fresh dill is not negotiable. Dried dill tastes like dust and has no place in this dish or in the dildsmor. If you can't find fresh dill, use fresh chives instead and call it a different butter. Don't pretend dried dill is a substitute. It isn't.
• •Nye kartofler have a season, and it's short. In Denmark they arrive in late June and the best are gone by August. If you're making this outside that window, use the smallest, freshest potatoes you can find. But if you can wait for the real thing, wait. The joy of waiting is part of what makes this meal feel like summer.
• •Serve a chilled Danish white wine alongside, or a good pilsner. Nothing heavy. The fish is delicate and the butter is rich. The drink should be cold and clean and stay out of the way.

Advance Preparation

• •The dildsmor can be made up to three days ahead. Keep it wrapped tightly in the fridge. It also freezes well for up to a month, so you can make a double batch when dill is abundant and have it ready when you need it.
• •Scrub the nye kartofler ahead of time and keep them in cold water until you're ready to cook. Don't cut them or they'll oxidize.
• •The trout should be bought the day you cook it, or at most the day before, stored on ice in the coldest part of your fridge. Fresh fish from a trusted fishmonger is the single most important ingredient here. If the fish isn't good, don't make the fish dish. Make something else.
