The original recipe calls for sierra mackerel, but halibut is more readily available. Chilies and other Mexican ingredients are available at Latin American stores and online. Tomatillos look like green tomatoes with a papery skin that is removed before using. Leave the seeds in the jalapeno for a hotter taste.
Ready time: 3 hours
You’d be better off with a citrusy, lean white, such as Rias Baixas or dry Sherry, both from Spain. Or try a frosty gin or vodka martini with lemon zest. - Beppi Crosariol

1/3 cup lime juice

Cut fish into 1/2-inch pieces and place in bowl. Stir in lime juice and salt and mix well. Refrigerate for about 2 hours.
