How to make
Roll out the puff pastry. Spread the surface with milk. Blanch the chopped spinach for 3 minutes. Strain through a colander and squeeze out the excess water well.
Arrange a few thin slices of ham on top of the puff pastry. This is optional, you can do without them. Spread the spinach and cottage cheese evenly on top. Put pieces of sausages in the two short ends of the puff pastry.
Fold one end to the middle of the puff pastry, then fold the other. Beat one yolk with a few drops of milk with a fork. Grease the roll.
Bake at 390°F (200°C) in a preheated oven with a fan for 5 minutes, then reduce the heat to 340°F (170°C) and finish off baking for about 25 minutes. Be careful not to burn the savory roll in the first 5 minutes.
Cool the baked roll with sausage and spinach on a wire rack. Slice it and serve it slightly chilled. Great appetizer!
