Melt butter in a small pot. Add milk and heat until the liquid is lukewarm, pour it into a bowl. Dissolve yeast in the bowl.Add egg, sugar, wheat flour, cardamom, and salt and mix well. Knead on a floured surface. The dough should be soft and pliable, not too dry.Let it rise for 1 hour.

Use an electric mixer to whip butter, marzipan, sugar, and grated apple together into a smooth mass.

Divide the dough in 2 and roll each half out into a rectangle (about 45 x 15 cm). Cut each rectangle into 8 triangles (see slide 4 for video).Put 1 tsp. remonce and a small piece of nougat at the bottom of each triangle and roll towards the tip of the triangle, so you get a horn with filling in the middle. Press the ends of the horns together well and place on a baking tray with the seam facing down.Brush with milk and bake at 200 degrees Celsius (392 degrees Fahrenheit), conventional oven for 10-12 minutes, until they are nicely golden.Decorate the cooled horns with icing and pistachios
