Tuna Tartare with Lime Crème Fraîche
A light, bright, citrusy hors d’oeuvre for a warm summer night, this tartare requires impeccably fresh tuna. Keep the fish on ice as you prepare it and serve it immediately for the most vivid flavor. To preserve the tuna’s plum-red color, don’t add the salt or soy sauce until the last moment. You can present the tartare in lettuce cups, if you prefer, instead of on fried wontons or crackers.
