Lamb and mint both have such assertive flavors, but put them together and somehow they manage to simultaneously enhance and tame each other—it really is a magical pairing. I wanted to bring those two flavors to these skewers, but knew I needed some other ingredients to complete the marriage. First, a marinade to help the mint adhere to the lamb—one made from yogurt was the logical choice, since it only adds to the synergy of both the lamb and mint. Plus, yogurt helps ensure that the lamb stays moist and tender as it cooks over high heat on the grill.
But lamb, mint, and yogurt, as great as they are, are a little too two-dimensional all by themselves. To add some more depth and complexity, I worked a few other ingredients into the marinade, including cilantro, lemon juice, garlic, and paprika.
For a final touch, I added red onion and zucchini to the skewers, alternating it with the pieces of cubed marinated lamb. They provide a nice touch of freshness that ends up being a perfect balance to the rich meat.
