Tried homemade Spanish dessert "leche frita" today: https://en.wikipedia.org/wiki/Leche_frita

Recipe is relatively simple but time-consuming: take 1 liter of milk, mix 200g with flour, eggs and species, other 800g goes into pot and cooked slowly. After some time, slowly put that flour/milk/eggs mix into hot milk (slowness required to prevent premature eggs cooking), then cook on low fire until it becomes dough-like. Then put in into refrigerator for day or such. After that you just need to fry them on pan.
