Olive Oil Poached Salmon With Lemon Dill Aioli; 5774 Recipe

If I served this poached salmon to my family in Israel, they would be certain I had lost my marbles. Not that they don't think so already, but this innocently swimming wild Coho, that was sacrificed for the sake of holiday symbolism, would seal the deal and I would be shipped off to an asylum. In comparison to my family's full of punch Indian and Israeli table, this poor little Coho fellow would be considered anemic. I thought so too years ago, until I developed the idiosyncrasies and appreciation for the delicately subdued.

When moving to the US, I was not prepared for the stripped down ingredients with minimal handling and seasoning. At the time, to me it tasted bland, and I didn't think of the technique or much needed handling with care that goes into the dish. I would totally discount it and turn my nose up. The little I had known that it is such a delicacy. For years, I would never touch that mandatory, to me, Ashkenazi (Eastern European Jewish) poached salmon on Rosh HaShanah, the Jewish New Year, when we were guests elsewhere. 

I have steamed salmon before in a bamboo basket but never poached it. It was still an epic steamed disaster. I have successfully poached duck in duck fat for duck confit on several occasions but had never, you guessed it, poached salmon before. I grew to love it even if it was not love at first sight. What motivated me to write about it is my instant spark for lemony dill aioli and the upcoming holidays.
Symbolically a whole fish is served head to tail on Rosh HaShanah, the Jewish New Year, to remind us, we all should aspire to be leaders like the head and not followers like a tail. More often than not, nowadays, you will see only fillets served, as some get queasy stomachs at the sight of a whole fish. 

While baking is considered more of a science, there are scientific elements to poaching, especially with olive oil. I knew there are idiosyncrasies to poaching salmon. A French technique called court boullion to highlight the ingredient in its purity. Poaching on the stove with other liquids like water, stock or wine or a mix is different.

I turned to my social media friends. All, @LDGourmet@cakeduchess@koshelikeme@divathaateny@MadHungryWoman@exceptionalfood and @StormsTunesFood unanimously said to immerse the fish COMPLETELY in a good quality, extra virgin, olive oil. Cooking method should be low and slow and the general consensus was to toss the olive oil away after the poaching process was done. One friend suggested to keep the oil. "It's an instant oil and omega 3 supplement" he said, which made sense, but I was too worried about the oil spoiling, even in the fridge to attempt it. You can follow the conversations here, here and here.
The oil engulfing the fish rises above any other liquid that is present. It locks in the moisture and keeps the fish from drying out. I found out an internal temperature of 140F-180F is ideal for a delicately flaky consistency. I had my oven at 250F but I didn't check the internal temperature of the fish with a thermometer. The fat content makes a difference too. I happened to choose Coho salmon which is lower in fat content than say Sockeye or farmed salmon so it will cook and dry out faster. Thickness of the fish varies cooking time as well. I kept it in the preheated 250F oven for 40 minutes. It was still moist but I suspect that even at 30 minutes it would be fully cooked and beautifully moist and flaky. Just test it with a fork.
The lemon dill aioli is such a classic and by far my all time favorite aioli. I really delight in it. I suspect if I slathered it on the fish and served it to my family, they would possibly be converts, just like me.

Lemon Dill Aioli

3 heaping tablespoons regular or lite mayonnaise (approximately 1/3 cup)
2 garlic cloves, minced
2 tablespoons finely chopped fresh dill
1 tablespoon plus fresh lemon juice
Two pinches of salt or according to taste

Mix all ingredients well with a fork, for about a minute, until a smooth consistency is achieved. Adjust lemon, salt according to your taste and keep in a jar, refrigerated until serving. The aioli can be prepped a day or two ahead.

Olive Oil Poached Salmon

1 1/2lbs salmon
1/2 lemon
1/4 teaspoon salt or according to taste
1 tablespoon capers
2 cups plus extra virgin olive oil

2-3 small cucumbers, unpeeled, sliced thin on a mandoline

Preheat oven to 250F. Wash the fish under cold water and pat dry with paper towels. In a heat resistant oven serving dish lay the fish skin down, squeeze lemon juice on top, salt it lightly, cover with olive oil and toss the capers on top. Cook for 30-40 minutes or until flaky and moist when forked. No pinkish rare salmon bits present. Take out of the oven and let cool to room temperature. Remove any capers off the top of the fish and overlay and decorate with cucumber scales. Serve immediately or cover and refrigerate until serving. Can be made a day ahead and served cold with lemon dill aioli on the side.

The fish can be decorated with the cucumber scales once cooled and refrigerated overnight. Surprisingly enough it keeps well while moistening the fish.
