I have never eaten, nor made, fish tacos but I've always wanted to. I just can never find a restaurant locally who makes them, or I forget to look on the menu until it's too late.
and I've never found a recipe that I have attempted.. maybe it's time to buckle down and do just that.
Where you live you should be able to buy tortillas. We like soft shell ( I know you can buy hard shell ones in stores in the US. Then start simple and cook your fish and add whatever toppings you like. First time I used lettuce, avocado, and a homemade dressing. They were tasty, but these I must say had to be the best so far!
