How to Make It
In a small bowl, mix the lime juice and zest with the sugar, 1 tablespoon of the fish sauce and one half of the minced jalapeños. Stir to dissolve the sugar, then stir the oil into the salsa.
In a small saucepan of boiling water, blanch the mint leaves just until wilted. Drain, refresh under cold water and drain again. Squeeze the mint dry, then mince; stir into the salsa with the scallion.
In a small bowl, mix the remaining 1 tablespoon of fish sauce, 2 tablespoons of mint and half of the jalapeños with the garlic and honey. Spread over the lamb steaks and refrigerate for 1 hour.
Light a grill; lightly oil the grate. Season the lamb with salt and pepper. Grill the steaks over a medium-hot fire, turning once, until browned, about 8 minutes for medium. Serve with the salsa.
