Heat oil in a pan and fry the pieces of hake, when you take them out put them in paper to soak the oil
Now prepare the mayonnaise in a home, to put them in the bowl of the mixer an egg, a splash of lemon juice, olive oil, a dash of vinegar (preferably lemon) and a little salt. Beat with mixer without moving the arm of the mixer. By the time you are emulsifying, seesaw arm slowly until the mixture is very smooth. Finally you can grate a little lemon peel
