Put the cheese in a bowl and with a fork, break it, so that it is as small as possible. Add wheat flour, semolina, lemon peel, sea salt, sugar, vanilla and egg yolks from the two eggs. Mix with a spoon or a wooden spoon until all the ingredients are homogeneous and we get a kind of cheese paste.
Separately, in another bowl mix the egg whites, using an electric mixer, until you get foam. Once we have obtained the foam, pour it over the cheese and mix it lightly with a spoon until all the foam is incorporated in the cheese and we obtain an airy, light composition. Put the composition in the refrigerator for about 20 minutes,
Fry the breadcrumbs in a dry frying pan, without adding oil or butter, and fry over medium heat, stirring constantly with a wooden spoon and taking care not to burn. After the breadcrumbs have taken on a copper colour, turn off the heat and add a tablespoon of sunflower oil and a tablespoon of sugar.
Boil the water in a pot then reduce the temperature to medium-low. With wet palms, make balls of cheese paste, the size of a golf ball, and put them in the pot to boil.
Boil the dumplings until they rise to the surface plus two more minutes (in total between 3-5 minutes) after which we take them out and put them over the fried breadcrumbs.
Lightly roll the dumplings in breadcrumbs so that they are completely covered with it and take them out in a serving bowl. Continue the operation until we finish with the whole amount of cheese paste.
Mix the cream Fraiche with the other ingredients, the sugar, vanilla and cinnamon and we will get a sweet and very fragrant cream with which we will serve the dumplings.
Serve the cottage cheese dumplings while they are hot, powdered with sugar and with this cream with vanilla or sour cream next to or on top.
