1poundfirm white fish, such as cod, tilapia, catfish
White Sauce
1/2cupmayonnaise
1/2cupMexican crema, or sour cream or crème fraiche (see notes)
3-4clovesgarlic, grated (or very very finely minced)
1tspsalt, adjust to your taste
Other Ingredients
vegetable oil for frying
tortillas
cabbage, finely shredded
lime wedges
How I Make It
Mix all the ingredients of the white sauce together and let it chill in the fridge for at least 30 minutes.
Mix all batter ingredients together with a whisk until smooth and there are no more lumps. The batter will have a runny consistency. Refrigerate and let the batter rest for 30-60 minutes before using.
Cut the fish into pieces, to whatever size you want. I cut mine into bite size pieces (either fish finger size or chicken nugget size).
Heat oil into a pan to about 350F (make sure there is enough oil to at least cover half the fish). If you don't have a thermometer, this is around the point where the oil looks shimmering like it's dancing but before it is smoking. Drop a little bit of batter in there and it should sizzle up.
Dip the fish into the batter and drop it into the oil. Fry it until golden brown. If you aren't using a lot of oil, this might require flipping the fish to cook the other side. It will take anywhere between 4-7 minutes to cook, depending on the thickness of your fish pieces.
Place the cooked fish pieces on a plate lined with a paper towel to absorb the excess oil. Season with a little salt.
Assemble your taco with fish, shredded cabbage, and white sauce. Squeeze some lime over top and enjoy!
Notes
For the white sauce, you can substitute the Mexican Crema with sour cream, creme fraiche, plain Greek yogurt or even plain regular whipping cream. If you use something that doesn't have a natural tanginess (like cream or half-half), you will want to squeeze 1 lime juice into it. The mayonnaise is important though, it gives the sauce its body so I would recommend leaving that in. Adjust the amount of garlic to your palate.
Tortillas - while corn is traditional, you can use whatever you prefer. I look for the smaller tortillas about 4-5 inches in diameter.
