Preheat oven (electric cooker: 200 °C/circulating air: 175 °C/gas: see manufacturer). Wash tomatoes and pat dry. Grate mountain cheese finely.
Place a large sheet of baking paper on the work surface and dust with flour. Unroll the pizza dough, turn over onto the floured baking paper and remove the baking paper (from the package) from the pizza dough.
Spread the cheese evenly on the dough, leaving an approx. 2 cm wide edge on the upper long side. Place the ham slices loosely on the cheese. Place cherry tomatoes on the bottom long side, approx. 4 cm from the edge, in a row.
Place the 4 cm wide edge over the cherry tomatoes using the baking paper and roll up the dough tightly. Lift the roll with the baking paper onto a baking tray and turn it so that the seam side is at the bottom. Bake the roll in a hot oven for about 35 minutes until golden brown.
In the meantime, mix sour cream and 1 1⁄2-2 teaspoon curry for the dip. Season to taste with salt and pepper. Cut the finished ham and cheese roll into slices and add the dip. Tastes hot and cold.
