The menu at Dune, the beachfront burger lounge at the Ritz-Carlton Hotel in Key Biscayne Florida, serves a delicious lamb burger with roasted red peppers and Manchego cheese on a grilled onion roll bun. Foraging on land that has little other agricultural use, and today still nearly completely grass fed, lamb is a healthy, sustainable option for meat lovers.The chef claims the secret to tender lamb burgers is to loosely pack the meat and to salt only the exterior of the lamb patties. This lamb slider riff using supermarket ground lamb has the perfect fat ratio and is no longer a special order item. Tzatziki, a yogurt, lemon juice, garlic, dill, and cucumber sauce, is a traditional condiment served with lamb. Make it tableside and use it like ketchup to spread on the bun for a tangy, refreshing, heat-cutting sauce. This tasty, lean, mean burger may be the new bbq favorite.
