Mark's Famous Spicy Shrimp
The best "bring-to-the-grill-party" dish ever, in my humble opinion; I've been doing it for 25 years.
Use the side of a knife, a small food processor, or a mortar and pestle to make a paste from a couple of minced garlic cloves, salt, a pinch or two of cayenne, and about a tablespoon each of good paprika or pimentón, olive oil, and lemon juice. Smear the paste all over a pound or so of shrimp. Grill or broil the shrimp for about two minutes on each side and serve with lemon wedges.
