0 Bring to a boil 6 cups of water. Have ready a bowl of ice water. Add peas and 1 tablespoon of salt to the water and cook the peas for about 3 minutes or until they are tender. Drain the peas and transfer them to the ice bath.
1 Bring another 6 cups pf water to a boil. Add the potatoes and another tablespoon of salt and cook until just tender, 5 to 10 minutes. Drain the potatoes and let them cool off in a single layer in a cookie sheet so they will not overcook.
2 Whisk together the lemon juice and olive oil
3 Combine the shallots and potatoes in a large bowl and toss with just enough of the lemon juice and olive oil to coat them well.
4 Rub the salmon all over with olive oil and season freely with salt and pepper. Heat a large skillet with a shadow of olive oil , over high heat. Add the fillet once hot and sear them without moving them for 4 minutes. Turn the fillets over and continue cooking until the salmon feels firm to the touch but still deep pink in the center. Another 3 to 4 minutes.
