I love seafood, and thankfully, most of it is very healthy to eat. I have tried sea cucumbers, numerous kinds of oysters, clams, and other shells. I keep expanding the numbers of fish I have sampled which currently includes swordfish, shark, catfish, bangus, lapu-lapu, halibut, tuna, salmon, trout, gar, perch, crappie, and a list of at least 10 more.
Shellfish are delicious, also. Crabs and lobster are my two favorites. I'm not sure if I prefer the giant king crabs or the smaller and sweeter crabs I ate in Asian countries.
Of the seafood I have tried, sea cucumber comes out as one of my favorites. I enjoyed it at an Asian get together where it was served fresh with a vinegar dressing along with tomatoes, onions, and fresh ginger. When I say fresh, that means uncooked.
The item that was my biggest challenge to try was sushi. I was very reluctant to eat raw seafood until after my experience with the sea cucumber salad. Now, I have discovered many kinds of sushi are delicious, and a few are equally atrocious.
