• Add the yeast, 1 teaspoon sugar, and ginger to ¼ cup warm milk and set aside.
• Put the remaining milk and butter in a microwave-safe bowl and heat until the butter melts.
• Let cool to 110F. It should feel comfortably warm to when you drop a few drops on your wrist.
• In the bowl of a stand mixer fitted with a paddle attachment combine 2 cups of the flour with the salt, sugar, and potato flakes.
• Add the yeast mixture and the cooled milk mixture and stir until blended.
• Add the egg and blend it in.
• Add another ⅓ cup of flour. The dough will be sticky.
• Switch to the dough hook.
• Add flour a tablespoon or two at a time until the dough doesn’t stick to the sides of the bowl.
• Knead until dough is smooth and elastic, about 5 minutes. It will still be a little sticky especially on the bottom.
• Remove from the mixer bowl and form into a ball.
• Rub the ball with melted butter then place it in a greased bowl.
• Turn the ball over once.
• Cover the bowl loosely with a clean tea towel.
• Let it rise for 1 hour, or until doubled in bulk.
• Punch dough down.
• Divide the dough into 10 equal pieces
• Roll into balls and arrange them 2 inches apart on a baking sheet lined with parchment.
• Brush with butter, cover loosely with tea towels or plastic wrap, and let rise for 1 hour.
• Make indentations in the buns and fill with cheese mixture or fruit filling.
• Sprinkle with crumb mixture.
• Bake at 425F for 8 to 10 minutes or until golden brown. Watch carefully.
