4 Arctic char fillets, 5-6 ounces each
20 large fresh morel mushrooms, or 1/2 ounce dried morel mushrooms
3 tablespoons olive oil, plus more as needed
1/2 teaspoon coarse kosher salt, plus more as needed
Freshly ground black pepper
1 pound slender asparagus, ends trimmed
1 medium leek, white and light-green parts only
1 1/4 pounds small red potatoes, sliced into 1/4-inch-thick rounds
1/4 cup Yusen vinegar (brown rice vinegar) or rice vinegar
2 teaspoons dry Japanese mustard or dry Colman’s mustard
1/2 teaspoon sugar
3/4 cup extra-virgin olive oil
1/4 cup minced fresh chives (about 1 large bunch)
If using dried morels, place them in a small bowl, cover with boiling water and let soak until softened, about 20 minutes. Drain well and pat dry. Combine 3 tablespoons of the oil, 1/2 teaspoon salt and a generous amount of pepper in a glass baking dish, and stir to combine. Add the asparagus and morels, and stir to coat. Let marinate while preparing the leek, potatoes and vinaigrette.
Bring a medium saucepan of salted water to a boil. Remove the outer 2 layers from the leek. Slice the leek crosswise into thin circles. Place the leek in a bowl of cold water and stir to break up the circles and release any dirt. Lift the leeks from the water, and transfer to the boiling water. Cook until slightly softened, about 2 minutes. Using a slotted spoon, transfer the leeks to a fine strainer and drain well. Add the potatoes to the water, and simmer until just tender, about 8 minutes. Drain well.
Meanwhile, prepare the vinaigrette. Combine the vinegar, mustard and sugar in a 2-cup glass measuring cup or medium bowl and whisk to dissolve the mustard. Very gradually whisk in 3/4 cup extra-virgin olive oil. Mix in the chives and leeks. Season to taste with salt and pepper.
Transfer the potatoes to a large bowl. Add 1/4 cup of the vinaigrette and toss to coat. Cover to keep warm.
Heat a heavy large skillet, preferably cast iron, over high heat. Working in 2 batches, remove the asparagus and morels from the marinade and arrange in a single layer in the skillet. Cook until almost crisp-tender and slightly charred, turning occasionally, about 5 to 6 minutes for each batch. Transfer the cooked vegetables to a work surface. Brush the char with olive oil and sprinkle with salt and pepper. Add to the skillet and cook until just cooked through, about 2 minutes on each side.
Cut the morels lengthwise into bite-size pieces. Cut the asparagus stalks on an angle into 1 1/2-inch pieces. Add the morels and asparagus to the potatoes. Add enough vinaigrette to season to taste and toss to combine. Taste and adjust the seasoning. Divide the salad among 4 plates. Peel the skin from the char. Arrange one fillet atop the salad on each plate. Spoon the vinaigrette with leek atop fish and serve right away.

Conservation Note Arctic Char, Farmed
Arctic char farmed in flow-through and recirculation systems in the United States, Canada, and Iceland are a “Best Choice” because the systems in which they are produced allow for significant environmental control and subsequently minor environmental impacts.
Arctic char are members of the salmon family and are most closely related to trout. Historically, wild stocks have been exploited in the native circumpolar range of the fish. However, char has been gaining popularity as a food fish and demand for farmed product is expected to increase in the future.
An environmentally-friendly substitute for farmed salmon, Arctic char is known as iwana when prepared as sushi. Arctic char are farmed in mostly recirculation systems that employ stringent biosecurity policies to facilitate pathogen- and chemical-free operation. The nature of these production systems indicate that such areas as effluent, chemicals, escapes, and disease all have minor environmental concerns. As the operations utilize juveniles solely from domesticated broodstock, no wild capture of fish is necessary.
While Arctic char are carnivorous and require high levels of fishmeal and fish oil, a large portion of feed ingredients are comprised of by-products (as opposed to whole wild fish). Recirculation technology is still quite young, yet its proven success indicates that higher volumes of seafood produced in these systems will become available as time goes on.
Overall, Arctic char farmed in flow-through and recirculating systems in the United States, Canada, and Iceland is a “Best Choice.”
