Split the shrimp through the shell on the rounded part as you would a lobster. Do not remove the shell. After all shrimp are split, pull to separate the meat from the shell (only pull the meat to the tail), then lay them back in the shell.
Lay the opened shrimp on a baking pan and brush with a mixture of fresh garlic and butter.
Crush the Ritz crackers finely. Sprinkle the crackers on the buttered shrimp, then pour more garlic butter over them. You may freeze them at this point or place in the refrigerator.
Place the pan in a 400 degree F oven, and bake until the crumbs start to brown.
