I find that white, lean fish work best for ceviche. I've made it with bluefish and salmon before but I don't like it so much; you might have a different opinion. My standard ceviche fish is Pacific rockfish or lingcod that's been pre-frozen. Any sort of snapper, grouper, black seabass, porgy, sea trout, white seabass or yellowtail will work, as will pre-frozen freshwater fish like walleye or perch.
1poundpre-frozen lingcod,rockfish or other lean, white fish
3limes
2lemons
1grapefruit
Salt and black pepper
1/2red onion,sliced root to tip
2Roma or other paste tomatoes,seeded
1ear of corn,kernels sliced off
1habanero or rocoto chile pepper,or more to taste
3tablespoonschopped cilantro
Instructions
Slice the fish into small, bite-sized pieces. Cut the tomatoes into pieces the same size as the fish and set them aside for later. Zest 1 lime, 1 lemon and the grapefruit and grate them fine; I use a microplane grater to do this. Mince the habanero fine. Juice all the citrus. Add all the ingredients except for the tomatoes and the cilantro to a bowl or plastic container with a lid and refrigerate for 30 minutes to 2 hours.
Add the tomatoes and cilantro, mix well and serve cold with chips.
