what is your favorite fish taco recipe?

I'm pretty agnostic when it comes to the fish - although we did it with some fresh caught catfish one time and it was great. But it's all about the sauce for us - sour cream, loads of lime zest, lime juice and a generous amount of salt. The sour cream makes it much lighter than using mayo. Also we usually use quick pickled red onions which help cut the richness, especially if you're frying your fish instead of grilling.... Now I'm wanting fish tacos for dinner.

I use black cod in a light batter. Deep fried. The traditional chopped cabbage and hot sauce or sometimes kimchi.

Just had fish tacos last night as it is such a favorite in our house! Used our go-to recipe http://www.epicurious.com/recipes/food/views/soft-fish-tacos-108046 from Bon Appetite 2003.
I have tried many variations over the years with batter / no batter / marinating and so on but this is hands down the best and favorite. You can add avocado to the tortillas and I add a splash of lime to the cream sauce and play with it but it always turns out delicious.

I made this for my daughter and I. It was delicious. I'm from Southern California and have spent a ton of time in Baja, so I love a good fish taco.
