My wife loves deep fried fish, but I rather have it baked or grilled. Try not to eat any deep fry any more.
By the time we realize we shouldn't eat things like deep fried, the damage is done. And pretty much to late in the game to change the outcome one way or another. IMHO.
We cook with lard quite a bit at home. But we don't actually cook all that much if that makes sesne. Like bacon and eggs in lard.... Sicne we do it 1-2 times a month MAX... I just don't sweat the little things.
Halibut makes good fish tacos is all I know. Maybe not as good as extremely rare tuna.. but damn good.
