Ingredients:
- 1 sheet (14.1 oz/400g) frozen puff pastry, thawed
- 8 oz (225g) thinly sliced roast beef (from the deli)
- 4 oz (115g) Gouda cheese, shredded
- 1 large egg, beaten
- 1 tablespoon poppy seeds or sesame seeds (optional)
- Salt and freshly ground black pepper, to taste
- 1/2 cup (120ml) sour cream
- 2 tablespoons prepared horseradish
- 1 tablespoon fresh chives, finely chopped
- 1 teaspoon lemon juice
- Pinch of salt
- Pinch of freshly ground black pepper
Instructions:
- Combine sour cream, horseradish, chives, lemon juice, salt, and pepper in a small bowl. Mix well and refrigerate until ready to serve.
- Preheat oven to 400°F (200°C). Line a baking sheet with parchment paper.
- Lightly flour a clean surface. Gently unfold the thawed puff pastry sheet. Roll lightly to even out thickness if desired.
- Evenly spread the shredded Gouda cheese over the puff pastry. Layer the roast beef slices on top of the cheese, leaving a small border around the edges. Season with salt and pepper.
- Starting from one long side, tightly roll the puff pastry into a log. Trim the ends to neaten them. Cut the log into 8 equal rolls.
- Place the rolls on the prepared baking sheet, cut-side up. Brush with the beaten egg wash. Sprinkle with poppy seeds or sesame seeds, if desired.
- Bake for 20-25 minutes, or until the rolls are golden brown and the puff pastry is puffed up.
- Let the rolls cool slightly on the baking sheet before serving with the chilled horseradish cream.
