First prepare the artichokes, following the instructions in the article, rubbing them with a cut lemon, quartering them and placing them in large bowl of water with a squeezed half lemon. Once completed, slice the artichokes thinly.
Using a deep frying pan, melt 60g of butter, add the artichoke slices and just cover them with water. Cook until soft.
In another pan make the béchamel sauce by melting butter, adding flour and slowly adding the milk, stirring all the time. Once the sauce is sufficiently cooked, thick with no lumps, add the cooked sliced artichokes.
Ready a large pan of boiling water with a large spoon of sea salt to cook the pasta sheets. Cook the lasagne sheets, making sure they don't stick to each other.
