First, cut the bratwurst in half lengthwise and then cut each piece into thirds. This way, each bratwurst will yield six pieces. Cook them in a nonstick pan over medium-high heat until they are nicely browned, then let them cool.
Next, thaw the puff pastry according to the package directions. On a clean surface, roll each piece into a rectangle measuring approximately nine inches by twelve inches. Using a pizza cutter, cut each rectangle into eight strips that are about one and a half inches wide. Then, cut each strip into two shorter pieces.
Now, it’s time to spread about half a teaspoon of mustard on each piece of puff pastry. Make sure to cover the surface evenly for that burst of flavor.
On top of the mustard, place about two teaspoons of sauerkraut on each pastry piece. Then, top it off with a piece of cooked bratwurst for that savory filling.
Coat one narrow end of each pastry piece with the egg wash. This will help seal the puff pastry around the filling, ensuring it stays intact during baking. Roll the puff pastry up and around the filling tightly.
Next, brush the outside of the rolled pastry with more egg wash and sprinkle with poppy seeds or caraway seeds for an added touch of flavor and texture.
Place the rolled pastries seam side down on a parchment paper-lined baking sheet. Then, pop them in the refrigerator for about fifteen minutes. This helps them keep their shape while baking.
Preheat your oven to four hundred degrees Fahrenheit. When ready, bake the German Style Pigs in a Blanket for about twenty-five minutes or until they are golden brown and flaky.
Finally, serve them warm with extra mustard on the side for dipping. Enjoy the delightful combination of flavors in every bite!
