Mix the lard and the sugar and then slowly add the eggs, the grated lemon peel and the cinnamon.
Add the flour and milk. Knead until you have a compact dough though not compact enough to roll it.
Let it rest for at least 30min in the fridge. Pre-heat oven at 180C.
Roll it with a roller. It should be 1cm. (Put flour on the superfice you are going to roll it on. Put some more on the roller)
Use cookie cutters and put them on a tray. If wanted paint with egg. Bake at 180C for around 20 min.
