Leeks In Jail

Preparation:

Preparation: Clean and blanch the leeks in lightly salted water. Drain and cut them in half (there should be pieces about 10 cm long). Chop the onion and brown it in a pan together with the oil and the peeled and chopped sausage. Add the tomato puree and cook for 20 minutes. Then pour in the cream and grate the nutmeg generously, thicken over medium heat for a few more minutes and adjust with salt and pepper. Allow the mixture to cool and mix with the egg yolk and the previously grated pecorino. Divide the puff pastry into 8 rectangles, arrange on each of them a spoonful of the sauce (well thickened) on which the leek will rest. Close the rectangle by decorating the edge with the prongs of a fork. Brush with the beaten egg yolk, arrange the bundles on the previously buttered oven pan and cook at 180 degrees for about 25 minutes.
