Step 1: Preheat the oven

• Preheat your oven to 400°F (200°C). Line a baking sheet with parchment paper.

Step 2: Prepare the lamb sausage filling

• If using sausage links, remove the casings.
• In a bowl, combine the lamb sausage, fresh herbs, and a pinch of salt and pepper. Mix until well combined.

Step 3: Roll out the puff pastry

• On a lightly floured surface, roll out the puff pastry sheet to smooth any creases.
• Spread a thin layer of Dijon mustard over the pastry, leaving a 1-inch border around the edges.

Step 4: Assemble the pastry

• Place the lamb sausage mixture in a log shape down the center of the puff pastry.
• Fold one side of the pastry over the sausage, then fold the other side to overlap, creating a tight seal. Pinch the edges to seal completely.

Step 5: Brush with egg wash

• Place the assembled pastry seam-side down on the prepared baking sheet.
• Brush the top and sides with beaten egg. For extra texture, sprinkle sesame seeds or poppy seeds on top.

Step 6: Bake the pastry

• Bake for 25–30 minutes, or until the pastry is golden brown and puffed. The internal temperature of the sausage should reach 160°F (71°C).

Step 7: Cool and slice

• Remove from the oven and let cool for 5 minutes. Slice into bite-sized pieces for appetizers or larger portions for a main course.
