Step 1

Scoop the avocado pulp into the bowl of a food processor. Add the sour cream, lime juice, garlic cloves, jalapeno, cilantro, salt, and pepper. Process until smooth. Check and adjust seasoning.

Step 2

Place in a dish, add the pit (this helps prevent it from turning brown), cover, and chill for an hour.

Step 3

Divide the shrimp in half. Coarsely chop one half and set aside. Put the remaining half in a food processor and grind to a coarse puree. Add egg, shallot, cilantro, jalapeno, and garlic to the processor. Process until smooth. Sprinkle mixture with breadcrumbs and process again. Transfer contents of the food processor to a large bowl. Add coarsely chopped shrimp and red pepper. Season with salt and freshly ground black pepper to taste. Mix well. Form burgers and chill for 1 hour (covered).

Step 4

Heat oil in a heavy skillet. When very hot, fry the shrimp burgers until golden, about 3 minutes per side, depending on thickness. Drain on paper towels.

Step 5

Serve plain, in a lettuce wrap or on an Onion Brioche Bun.
