Light a grill. In a small saucepan, combine the garlic and 1/2 cup of the olive oil; simmer over low heat until the garlic is golden brown, about 8 minutes. Transfer the garlic to a blender and pour the oil into a glass measuring cup. Let the oil cool slightly. Add the habanero chile to the blender with 1/4 cup of the cilantro, lime juice, and honey; puree until smooth. With the blender on, slowly add the garlic olive oil. Season with salt and pepper.

Brush the shrimp with olive oil and season with salt and pepper. Grill over a hot fire until lightly charred, about 4 minutes per side. Shell the shrimp and transfer to plates. Drizzle with the vinaigrette, sprinkle with the remaining cilantro, and serve.
