Heat yolks over double boiler. Slowly whisk in butter. Finish with spices and lemon juice.
Preheat oven to 350 degrees.
Stretch puff pastry by 50 percent with rolling pin dusted with flour. Cut into 6x1/2-inch strips and brush with egg wash.

Sprinkle with remaining parmesan cheese and bake 15-20 minutes.
Top with hollandaise and enjoy!
