Poached Cod with Miso-Ginger Vinaigrette

A few years ago I made this latin 5-star poached cod, and today tried an Asian variation. As before, the fish was perfectly cooked; moist and tender. The flavors were balanced, but the flavors were more subtle than the previous Latin variation. I simply added more sauce to my plate, and it worked out great. It did take me quite a while for me to find the white miso paste required for this recipe (which turns out to be in the refrigerated Asian section). I ended up going to an Asian supermarket. Overall, a delicious 4-star meal; but not as good as the 5-star Latin version.

  1. In Chris Kimball’s original recipe, he says to let the oil cool down to 180-degrees. Today I cooked the scallions for 4 minutes and had to wait about 5 minutes for the oil to cool down. When I made the Latin-themed version and I fried the jalapenos for only 2 minutes, I had to heat up the oil in step 5 instead of allow it to cool.
  2. Trying to find a flaky white fish that is a consistent 1″ thick is difficult. The thinner parts were almost as delicious, even if there were slightly over-cooked.

Chris Kimball’s original recipe is here.  The descriptions of how I prepared the soup today are given below:

4 skinless white fish fillets about 1″-thick.
Kosher salt
8 scallion whites
2 teaspoons cornstarch
3/4 cup olive oil
1/2 peeled onion
2 radishes, halved and thinly sliced
2 scallion greens, thinly sliced

Vinaigrette:
6 scallion greens
8 teaspoons lime juice
2 tablespoons mirin
4 teaspoons white miso paste
2 teaspoons minced ginger
2 teaspoons pepper
1/2 teaspoon sugar

  1. Set a rack to both the middle and the lower-middle of your oven, and pre-heat to 250-degrees.
  2. Cut your fish into 6-oz pieces and pat dry using paper towels. Sprinkle each fillet with 1/4 teaspoon kosher salt. Allow to sit at room temperature for 20 minutes before cooking.
  3. Meanwhile, Slice the scallions whites into 1/4″ slices. Dredge your scallion whites in corn starch. Cut your onion if half, peel one half and save the second half for another day.
  4. Set a 10″ non-stick skillet over medium burner. Add 1/2 cup oil and pre-heat until shimmering. Fry scallion whites for 3 to 4 minutes until crisp. Pour the contends of the skillet through a fine-mesh strainer into a Pyrex measuring cup. Remove fried scallions to paper towel–lined Pyrex pie plate or casserole dish. Sprinkle with a little kosher salt. No need to wash the strainer yet.
  5. Increase amount of oil in measuring cup so that you have 3/4 cup, and pour back into the skillet (but off the heat). Put the onion cut-side-down in the center of the skillet. Allow the oil to cool to 180-degrees, which could take between zero and 8 minutes.
  6. Meanwhile, prepare your ingredients for the vinaigrette. Roughly cut the scallion greens and add to blender. Add lime juice, 2 tablespoons mirin, 4 teaspoons white miso paste, 2 teaspoons minced ginger, 2 teaspoons pepper, 1/2 teaspoon sugar; but do not blend until step 10. (you’re still waiting to add some olive oil from the fish)
  7. Place fish with skin-side-up in oil, which should rise to cover about half-way up the fillets. Spoon a little oil over each piece of fish, cover your pan, and place on middle rack and cook for 15 minutes at 250-degrees.
  8. Remove covered skillet from oven and flip fish using two spatulas. Replace lid onto skillet and place on middle rack and continue to cook for 10 minutes longer until the internal temperature of the fish reaches 135-degrees. After 5 minutes of cooking put the fried scallions on the lower-middle oven rack to warm them through.
  9. When fish reaches desired temperature, place on serving platter and tent with aluminum foil.
  10. Add 1/2 cup of the olive oil used to cook the fish to blender. Blend for 1 minute on high-speed. Add any juices from fish that have accumulated to blender, adjust salt according to your taste. Blend for 10 more seconds on high-speed. Run vinaigrette through fine-mesh strainer and use a rubber spatula to press solids down to extract as much vinaigrette as possible.
  11. Place each fish fillet on individual serving place and top with fried scallions, radish slices and sprinkle with thinly sliced scallion greens. Drizzle vinaigrette around each individual piece of fish (not on-top). Serve remaining vinaigrette separately.

    So … is the onion used just to raise the level of oil in the pan?

    I just made this recipe and truly it was marvelous. One question – is the cornstarch called for in the recipe meant to be used?
