- 4 ounces fresh Mexican chorizo, casings removed
- 1 1/2 sticks unsalted butter, cut into 1/2-inch cubes
- 2 tablespoons fresh lime juice
- 18 Louisiana or other medium to large oysters, scrubbed
- Cilantro leaves and finely grated lime zest, for garnish
- In a skillet, cook the chorizo over moderate heat, breaking it up with a spoon, until lightly browned, 8 minutes. Scrape into a bowl and let cool, then break into small clumps.
- Add 1 tablespoon of water to the skillet and simmer over low heat. Add the butter to the skillet a few cubes at a time, whisking constantly until melted before adding more. Stir in the chorizo and lime juice and season with salt. Keep warm over very low heat.
- Light a grill. Place the oysters on the grill, flat side up. Grill over high heat until the shells open slightly. Carefully transfer to a platter and, using kitchen gloves or a mitt, remove the top shell. Spoon the chorizo butter onto the oysters and garnish with a cilantro leaf and lime zest. Serve right away.
Usually, oysters are served with sparkling wines, but the intensely flavorful chorizo butter here allows for a more full-bodied wine, like a minerally Chablis.
