Soproni mandulás rétes is a variety of a traditional Hungarian strudel that is considered a specialty of Sopron cuisine.
It typically consists of a thin pastry dough that's been filled with a fruit preserve or jam and almond cream (similar to frangipane) before it's baked until nicely colored and crispy. According to the traditional recipe from Cuisine of Hungary, a cookbook written by the famous restaurateur and cookbook writer George Lang, this sweet delicacy is made with strudel dough, melted lard or butter, raspberry or strawberry jam, ground almonds, sugar, and eggs.
