Remove pastry puff from freezer, make calcium water for the pectin according the package instructions. Squeeze and strain the juice from 1 lemon. Place rinsed piquillo peppers into a food processor with the vinegar, sugar and pepper flakes. Mix well to create a smooth texture, place in a medium sized pot and bring to a boil over medium heat. Keep a close eye on the mixture, and whisk well while heating. Once it comes to a boil, remove the pot from the heat and allow it to cool for 15-20 minutes. Add the lemon juice, place it back on the heat and return it to a boil. Add the calcium water and pectin, whisk well, remove from the heat and allow to cool completely before using. The jelly can be stored in an airtight container in fridge for about 2 weeks. It’s also lovely paired with a cream cheese and crackers or as an accompaniment to a sandwich or even mixed into a salad dressing!
Place cream cheese, mayo, salt and green onion into food processor and blend until it’s emulsified and a light green color. Dice the ham steak into 1/8-inch cubes and fold into cream cheese mix.
Roll out the thawed puff pastry on a lightly floured surface. Cut it into 3×3-inch squares and place about two teaspoons of cream cheese filling into the center of each square. Fold the square over diagonally and press down to seal the edges. Whisk one egg in a bowl and using a pastry brush, cover each pastry with some of the egg wash.
Place the puffs, spaced evenly apart, onto parchment paper on a cookie sheet. Place cookie sheet in freezer overnight or for at least 2-3 hours. When ready to bake, preheat the oven to 425°. Place the cookie sheet, directly from the freezer, into the oven and bake for for 12-15 minutes. Pastry should appear golden and flaky, almost doubling in size. Enjoy with more red pepper jelly, a glass of bubbly and good company.
