How to cook
Beat the eggs with the sugar very well. To them add the lemon zest, vanilla + butter. Crumble the yeast in a little milk, add 1 tbsp sugar, 1 tbsp flour and wait for it to rise.
Sift the flour in a deep bowl, form a well, pour the egg mixture into it, along with the rest of the milk and effervescent yeast. Knead a dough and keep kneading a long time after bubbles form.
The dough needs to be soft, easy to knead but not to stick either. Put it in a warm area to rise. Then divide it into 2 balls.
Make wicks out of each one, twist them together or wrap into a spiral and place them in oiled oven dishes.
Put the cozonacs to rise again in a warm area and then smear them with beaten egg yolk + a little water and pour sugar over them. Bake in a preheated 320°F (160 °C) oven.
