REFRIGERATE MAYO RECIPES

Steps:

• For the shrimp burgers: Coarsely chop half of the shrimp. Put the remaining shrimp in a food processor and pulse until smooth. Combine both shrimp in a large bowl with the breadcrumbs, lemon juice, salt, garlic powder, pepper, scallions and egg and mix. Refrigerate for 10 minutes, and then form into 4 patties. Refrigerate 10 more minutes.
• Heat the oil in a large cast-iron skillet over medium-high heat. Cook the burgers, about 3 minutes per side.
• For the Old Bay mayo: Combine the mayonnaise and Old Bay to taste in a small bowl.
• To serve, spread the buns with the mayo and place the burgers on the buns. Top the burgers with the avocado slices, lettuce leaves and tomato slices.

Steps:

• In a glass bowl, whisk together egg yolk and dry ingredients. Combine lemon juice and vinegar in a separate bowl then thoroughly whisk half into the yolk mixture. Start whisking briskly, then start adding the oil a few drops at a time until the liquid seems to thicken and lighten a bit, (which means you've got an emulsion on your hands). Once you reach that point you can relax your arm a little (but just a little) and increase the oil flow to a constant (albeit thin) stream. Once half of the oil is in add the rest of the lemon juice mixture.
• Continue whisking until all of the oil is incorporated. Leave at room temperature for 1 to 2 hours then refrigerate for up to 1 week.
