We love grilled salmon, though I've never made a rub for it before. I found this recipe and decided to modify it.
Grilled Salmon with Peppercorn-Lime Rub
2 tsp grated lime rind
1/2 tsp kosher salt
1/2 tsp cracked black pepper
1 garlic clove, minced
4 salmon fillets
Lime wedges (optional)
Combine lime rind, salt, pepper, garlic and a splash of lime juice. Rub over the flesh of the salmon fillets and let sit for 15 minutes.
While fish is resting, preheat the grill to 400ºF. Add fish, skin-side down, and grill about 8 minutes until it flakes easily with a fork and is still somewhat pink in the middle. Tent with foil and let rest a couple minutes. Remove skin and serve.
