Start by mixing warm milk and a little sugar in a bowl. Add yeast, wait 7 to 10 minutes until it bubbles.
In another bowl, mix all-purpose flour, potato flour (or more all-purpose flour), sugar, and salt.
Melt butter in a separate bowl.
In a big bowl, mix egg, milk-yeast mix, and flour mixture. Mix well.
The dough will be sticky. Add more flour if needed.
Cover and let it rise for an hour.
Knead, let it rest for another hour.
Divide dough into 8 pieces. Put cheese, sausage, jalapeno, fold dough.
Let it rest, then bake at 350°F (175°C) for 18-22 minutes.
Let cool a bit. Serve your Shipley's Kolaches warm. Enjoy!
