Puff pastry tarts are thankful recipes that allow your creativity to run pretty much free and the chances to get them wrong are still rather low. For this one we have used good quality cod loin, potatoes and gratinated home made garlic mayonnaise. It will make a great starter or even a main if served with some green salad for example.
Garlic mayonnaise is a stable cold emulsion made of garlic, egg yolk and oil. It is sometimes confused with alioli, typical from Catalonia, although the later does not use egg. In as little as 10 minutes, you will prepare a delicious garlic mayo that has nothing to do with anything you can buy at the supermarket.
