Ingredients
HERB MAYONNAISE:
2 large egg yolks (as fresh as you can get)
1 teaspoon Dijon mustard
1 tablespoon white wine vinegar
1/2 teaspoon kosher salt
1/4 teaspoon white pepper
1 cup safflower or grapeseed oil
Juice and zest of 1/2 lemon
2 tablespoons chopped fresh basil
2 tablespoons chopped fresh flat-leaf parsley
2 teaspoons chopped fresh tarragon
SHRIMP BURGERS:
1 pound medium shrimp, peeled and deveined
2 tablespoons fresh flat-leaf parsley, finely chopped
2 tablespoons finely minced shallots
1 garlic clove, finely minced
1 teaspoon Old Bay Seasoning
Kosher salt and freshly ground black pepper
Pinch of cayenne pepper
2 tablespoons olive oil
1 head frisée, endive or oak lettuce
Juice of 1/2 lemon
4 buns, split
Instructions
Combine the egg yolks, mustard, salt, white pepper and half of the white wine vinegar. Whisk until very smooth and slightly thickened, about 30 seconds. Slowly drizzle in the oil, 1 tablespoon at a time, while whisking vigorously and wait for the oil to completely combine with the egg mixture before adding another tablespoon. The mixture should begin to thicken and will turn a pale yellow color. Continue to add the oil in this fashion until all of the oil has been used. When emulsified, the mixture should be very thick and will look almost exactly like store-bought mayonnaise, but will be a beautiful yellow color that you only get from homemade mayo! Add the remaining white wine vinegar; taste for seasoning and add salt and pepper, to taste. Add the lemon zest and juice and the chopped herbs and whisk to combine. Store in the refrigerator until ready to use.
In the bowl of a food processor, add half of the shrimp and pulse several times to finely chop. Transfer to a large mixing bowl. Finely chop the remaining shrimp and add to the bowl. Add the parsley, shallots, garlic, Old Bay, cayenne and salt and pepper. Gently mix to combine, taking care not to overmix. Form into four patties, place on a baking sheet and refrigerate for at least one hour to firm up the mixture.
In a large nonstick skillet, heat 1 tablespoon of the olive oil over medium-high heat. Add the shrimp burgers and cook for 4 to 5 minutes per side. You may have to cook the burgers in two batches. While the burgers are cooking, make the salad. Add the lemon juice and remaining 1 tablespoon olive oil. Toss the greens in the dressing.
To serve, spread the mayonnaise on both sides of the buns. Place the burgers on and top with the salad.
