The secret to our chicken tikka masala is a salty yogurt-based marinade followed by intense charring on a hot grill. We purposely undercook our chicken so it can simmer in a creamy spiced tomato and cream sauce before serving. When done right, the sauce should be a multifaceted affair; a balanced blend of intense spice flavors with a gingery kick rounded off by the richness of cream and butter, with a splash of freshness and acid from tomatoes and citrus. As you bite into a chunk of chicken, the smoky char should work its way though to the forefront, to be slowly replaced by a new layer of spicing, this time intensified by its time on the grill. The chicken chunks should be juicy, moist, and tender.
