SASHIMI!!!
Slice that belly up super thin and roll it up with some rice in nori- even if it's been frozen once it's still going to be good raw eating. The steak can be thin-sliced and served the same, or just as slivers. I love thin-slicing halibut and tuna and serving it on a frozen block of salt.
CEVICHE!!!
There are a ton of 'ceviche' recipes out there and pretty much all of them are not traditional Peruvian or Chilean. But they're pretty much all good! Most think of ceviche as almost a form of sashimi- toss the fish in a bath of lemon juice for a few minutes then eat it. That's not the way it's supposed to be made, it's supposed to 'cook' in the acid for quite a while.
1 pound fish, cut into 1 inch cubes
Lime juice (1 cup juice- the best is to squeeze a ton of wee little Key Limes, but you can use full-sized limes or concentrate if that's all you have)
Juice of 1 large orange
5 green onions, chopped
1 medium red onion, diced
1/8 cup lightly packed cilantro leafs, chopped
1/4 cup lightly packed arugula leafs, chopped
1 tomato, chopped
PEPPERS! Jalapeno, Habanero, Limo, whatever you want. Rocotos are what are traditionally used, I prefer C. chinense over annuum species but you can use whatever and however much you want. I usually chop them based upon heat- i.e. the hotter they are the finer I chop them.
DO NOT USE METAL POTS AND PANS!
- Cut the fish into cubes and place in flat bottomed glass container. Pour in enough lime and orange juice to cover the fish. Cover and refrigerate overnight, or about 4-8 hours
- Remove fish from the fridge, add all other ingredients. You can remove the lime juice or a portion of it if you wish before adding the other ingredients, it's up to you- I'll remove some of it usually.
- Cover again and refrigerate for 8-12 hours, depending on taste (some don't like so much lime)
- Remove from fridge, place in glass bowl to serve. Sprinkle with salt to taste.
