It's one of the old recipes from my mum's notebook which she got from her colleague at work. I came across quite a dilema while translating the name of the dough the croissants are made of. It says in the notebook that it's "half-puff pastry" but I think it's much closer in the texture to shortbread and that's why I've decided to stick to it. If somebody knows about the exact name for this pastry in English please let me know in your comments!
Irrespective of the name, the croissants were extremely popular during our last family gathering. They are really delicious and literally melt in your mouth. If you add you home made plum marmalade (which I don't have this year, unfortunately)- they will disappear from the table very fast :)
