thanks lifter, never heard of that. i usually don't go to a fancy fish monger, just my local supermarkets, whole foods, and occasionally a specialty fish shop.
yep, with a lot of smaller fishes, it's best to throw away the belly dark meat. but tuna belly is prized, especially in the sushi world.
The way that you wander is the way that you choose. The day that you tarry is the day that you lose.
Sunshine or thunder, a man will always wonder where the fair wind blows.
