Guys, I took the liberty of copying Zed's recipe he mentioned in the trip reports section over to here as it sounds like a sweet one and one i will be trying at the earliest possibility.
~1 lb fish sliced 1/8" thick (for CM users: ~1x2.5x4.5cm pieces. Big enough to grab w/ chopstix, but thin enough to "cook" in the citrus)
1/2 cup fresh squeezed lime juice (2-3)
1/2 cup fresh squeezed lemon juice (2-3)
1/2 cup fresh squeezed orange juice (2-3)
1/2 cup soy sauce
1/4 cup sweet chili sauce (you can find this in the condiments sections of asian stores usually labeled as sweet chili sauce for chicken: spicey and sweet)
2 T sesame oil (or sesame dressing)
1/4 cup sliced green onion (3 bunches)
1/2 bunch chopped cilantro (asian parsely)
Mix everything but fish in a (edit: NON-REACTIVE) bowl, season the fish (I added some crushed red pepper flakes here) and toss it in the marinade and put it in the fridge for at least 1 hour. Serve over cooled rice.
I just made this last night with some yellowtail (king) I got on a boat trip. Oh baby is it good. The sierra mackerel on my side of the lake (In MEX) is great for this type of recipe and is similar to the spots you see.
Try it <drool>...
