There’s not much of a story here, only an observation my sister made that it seems like I’m into fancy food lately. I attribute this to spring break, when I made the dishes in my last three posts, because I had some time on my hands and I wanted to play. This recipe, and the deviled eggs crostini from last month, came from a list I keep on my laptop of food ideas, which oddly enough doesn’t often get used – I write down delicious-sounding concepts, and then I forget about them.
Not so with this one anymore. Very loosely imagined after a dish N. had years and years ago on the Oregon coast that just wasn’t as good as it should have been, I decided to top salmon filets with an herby crab salad, then wrap the whole thing in wafer-thin slices of potato and serve it over a velvety smooth puree of peas and arugula. Very spring.
The finished dish was good, and the flavor was delicious. It was not, however, as perfectly beautiful as it could have been, largely because I think to make this dish as gorgeous as it deserves to be, you really need a mandolin or a v-slicer, which is equipment I don’t have (largely because my kitchen storage situation leaves a bit to be desired). I made do with a potato peeler, as can you, in a pinch, but the results were only passable, not stellar.
Notes below about crab and puree options: jumbo lump is, of course, the premium choice, but lately I’ve found a mixture of jumbo or regular lump and claw meat is just fine. As for the puree, as I note below, you can choose your texture to please your palate (and your partner’s); I went with something pesto-like, but processing or blending further would offer a smoother sauce, and passing through a strainer, though somewhat time consuming, would produce a silky bright green sauce. Proceed as desired.
Potato Crusted Salmon with Pea and Arugula Puree
About 45 minutes
Serves 2 (with leftover crab salad)
For the crab salad:
Zest of one lime
Zest of one lemon
3 TB finely minced dill + a few extra sprigs to garnish if desired
1 TB finely minced chives
2 TB finely minced celery and/or radish
10 ounces crab meat, carefully picked through for cartilage pieces
about 3 TB mayonnaise
salt and pepper to taste
For the salmon:
2 6 ounce boneless, skinless salmon filets
3-4 medium Yukon gold potatoes
salt and pepper to taste
1 TB butter
1 TB olive oil
For the pea and arugula puree:
4 ounces defrosted frozen peas
2 TB butter
2 ounces baby arugula
1 TB lemon juice or to taste
salt and pepper to taste
Optional: blanched pencil asparagus
- First, make the crab salad: combine all ingredients in a medium bowl. You can use whatever sort of crab you want; I like a mixture of lump, for the sweetness, and regular or crab and claw meat, for the affordability. Start with the recommended 3 TB mayonnaise, but you can add more if desired. You are looking for just enough that the mixture starts to hold together. Set the finished crab salad aside until it is time to assemble.
- For the salmon, preheat the oven to 375F. Do a quick but thorough check of the filets to ensure there are no bones. Salt and pepper the fish on both sides, then set aside until the potatoes are ready.
- The easiest way to proceed is to make very thin vertical slices of the potatoes on the wider side using a mandolin slicer, so you end up with long, wide strips. If you are using a mandolin, you will probably only need 2 potatoes worth of wide strips. Use the third potato to make round slices, like potato chips, by cutting horizontally across the small ends. If you don’t have a mandolin, you can do a passable job with a y-shaped potato peeler. Again, try for the longest, widest slices you can manage. You’ll probably need all 4 potatoes if you are using a peeler, because at a certain point you won’t be able to carve out clean slices anymore. Use 3 of the potatoes to make the long, wide strips, then use the fourth one to make the round, potato chip shaped slices.
- To assemble, on a cutting board, lay out a row of long, wide potato strips, slightly overlapping, about an inch longer on each side than the filet. Add a second row just above it, again overlapping, so you have a kind of carpet of potato slices, as in the photo below.
- Set the filet in the center of the potato slices, flesh side up (that is, the side where the skin used to be should rest on the potato layer). Using a spoon, top the filet with a few tablespoons of the crab salad, spreading it evenly across the surface.
- Now the hard part: working quickly, begin wrapping the potato slices around the salmon. As you bring the overlapping layers up to the top, shingle on a layer of the round slices to hold the long pieces up and together. Check out the photo below to see what I mean.
- Okay, now the other hard part: heat the butter and olive oil together in a medium skillet over medium high heat. When the fat is quite hot, use a spatula and your hand to carefully but quickly add the wrapped filets to the skillet, trying to get the shingled top side into the butter and oil mixture first. Sear without disturbing for 4 minutes, then carefully flip and place the whole skillet into your preheated 375F oven for 10 minutes.
- While the fish is in the oven, make the pea and arugula pesto: in a small pot, cook the peas with the 2 TB butter just until they are hot. Add them to a food processor with the arugula, the lemon zest, and a pinch each of salt and pepper. Process until fairly smooth, then taste for seasoning and adjust as needed.
- If you want to be fancy, you can strain the puree until a thin, smooth sauce. I decided to leave it more like a pesto texture, though, for ease.
- If you are making the asparagus, now is a good time to blanch it and toss it with a tiny bit of butter, lemon, and salt.
- To serve, place a scoop of the puree in the center of a plate or a shallow bowl. Use the back of a spoon to spread it into a circle. Alternatively, if you strained the mixture into a sauce, just pour some into the bottom of the vessel you’ve chosen. Place the potato-wrapped fish carefully just to the side of the center, so you can see some of the bright green circle underneath. If you made the pencil asparagus, you can nestle this between the fish and the edge of your plate or bowl, as in the photo earlier in the post.
