I'm in south OC and I just might consider contacting you for my next big catch.
PM me when you put a heavy one in ice and I'll give you a bunch of good info to make a great poke' bowl. I know a few other easy ways to make sushi without making rolls. Rolls impress your friends but take a lot of time. With the poke' bowls, just set out all the ingredients and let friends go at it.
Check out the sushi I made last year from Yellowtail. I really enjoyed the cucumber one, delicious and easy to build. Also, the deep fried garlic and ponzu hamachi (last pic, on the far right) is stupid delicious and even easier to make.
I know...I know...My reports are super long. lol
