Source:  Week of Menus Blog

2 lbs of jumbo shrimp, legs removed,
de-veined and butterflied (see step by step photos below)
1/4 cup of butter, softened (softer the better)
1/4 cup olive oil
1/4 cup chopped cilantro
1/4 cup chopped red pepper
(red bell pepper is fine, but if you like SPICE, use a red chili pepper)
3 tablespoons of finely chopped garlic
1 tablespoon lime juice
Sea salt and cayenne pepper(optional) for sprinkling

Arrange oven rack so that it is closest to the heating element. Preheat oven to broil. Line sheet pan with foil. Place prepared shrimp evenly so that there is only a single layer and every shrimp will get maximum heat.
