Ingredients:
For the shrimp:
1/2 onion, thinly sliced
1/2 carrot, thinly sliced
1 teaspoon canola oil
2 slices peeled fresh ginger, each the size of a quarter
1 teaspoon coriander seeds, toasted
1/2 bay leaf
1 lb large shrimp, peeled and deveined, shells reserved
2 tablespoons olive oil
kosher salt
2 garlic cloves, sliced
1/4 cup white wine
1 tablespoon salt packed capers, rinsed and drained
For the vinaigrette:
1 shallot, minced
kosher salt
grated zest and juice of 2 lemons
2 tablespoons chopped fresh dill
1/2 cup extra-virgin olive oil
In a small sauce pan over medium heat, sweat the onion and carrot in the canola oil until softened, 2 minutes. Add the ginger, coriander, bay leaf, and shrimp shells and cook until the shrimp shells are pink. Add 2 cups water and bring to a simmer. Simmer on low for 15 to 20 minutes while you prepare the dill vinaigrette. When you're ready to cook the shrimp, strain the stock through a fine mesh strainer into a measuring cup. You'll need 1/2 cup.
To make the vinaigrette, combine the shallot in a bowl with a pinch of salt. Add the lemon zest and jice and the dill. Whisk in the extra-virgin olive oil and add more salt if needed.
To cook the shrimp, heat the 2 tablespoons of olive oil in a large sauté pan over medium heat. Season the shrimp with salt, add them to the pan, and cook for about 2 minutes per side. Add the garlic and cook for 1 minute. Deglaze the pan with the white wine. Add the 1/2 cup stock, bring it to a simmer - making sure to scrape any particles off the bottom of the pan with a wooden spoon - and let it reduce for 1 minute.
Divide the shrimp among plates. Add the capers to the pan, whisk in the vinaigrette just to heat through, and pour the pan sauce over the shrimp.
