The dough is made of flour, sugar, egg yolk, milk or sour cream and butter, and yeast. The dough may be flavored with lemon or orange zest or rum. The poppy seed filling may contain ground poppy seeds, raisins, butter or milk, sugar or honey, rum and vanilla. Sometimes a tablespoon of apricot jam, which is one of the most popular jams used in Hungarian cuisine, is substituted for sugar. The walnut roll filling contains raisins, rum, butter or milk, lemon rind and chopped walnuts. This filling may be spiced with cinnamon, nutmeg, clove or vanilla. The dough is at first quite heavy, stiff and dry, but with kneading and resting becomes very elastic and strong. It is rolled out into a large sheet, thick or thin depending on taste. One aesthetic principle is that the dough and filling layers should be of equal thickness. Another is that more layers are better. The filling is spread over the dough, which is then rolled into a long cylinder or log. Traditional recipes usually involve brushing the log with the egg white left over from the yolk used in the dough. Other recipes use different washes, or an icing added after baking. The unbaked log is gently transferred to a sheet pan, left to rise, then baked until golden brown.
Variants
The poppy seed filling is a paste of ground poppy seeds, milk, butter, sugar and/or honey, often with additional flavorings such as lemon zest and juice. It may have raisins. The walnut filling is a paste of ground walnuts, milk, butter, sugar, and raisins, often with additional flavorings such as coffee or orange zest. A very long roll may be bent so that it fits on a baking sheet; the result is called a patkó in Hungarian. Before baking, the roll may be given a wash of milk. The roll can be finished with an icing after baking, made of powdered sugar and lemon juice. Usually it is brought from the kitchen already sliced. In Hungarian cuisine, the rolls, one with each filling, are served together. The combination is known as mákos és diós. However, in some English languagecookbooks there may be no mention of the walnut filling, as if poppy seed were the only filling used. Some other food writers combine the poppy seeds and walnuts together in one filling. Because Polish and Czech culture have intermingled, immigrants to America sometimes use the term "Kolache" to describe it. As a new trend, a chestnut-filled variant is emerging, mainly among younger urban families.
