Mix milk, eggs, salt, sugar, duck fat (or 2 tablespoons of melted butter) into a microwave safe mixing bowl. Microwave for 30 seconds to take some chill out of the mixture. Add the yeast and stir to combine.

Add the milk mixture to the bowl of a stand mixer. Add the flour and potato flakes to the bowl. With a dough hook attachment, mix on medium low speed for about 8 minutes until a smooth dough is formed. It should be just pulling away from the sides of the mixing bowl. If the dough appears to be too wet/sticky, add in a tablespoon of flour at a time until the dough pulls away from the mixing bowl after mixing.

Lightly grease large mixing bowl. Place the dough in the bowl and cover the bowl with a towel. Place in a warm section of your house and let the dough proof, until it has doubled in size. This will take about 1.5 hours.

Press down on the dough with your hand to release the gases.

Grease a large baking dish or sheet pan and set aside. You'll be placing the dough on it after you've assembled the rolls.

Lightly dust a work surface with flour. You're wanting to dust about a 14x14 inch work surface in which you'll be rolling the dough out on.

Place the dough onto the floured work area and shape into a rectangle that's about 12 x 14 inches in size.

Lightly brush the dough with butter.

Using a kitchen knife, cutting vertically, cut around 2 inch even strips of dough. See picture below the directions.

Now, cutting horizontally, cut all of the strips down the middle. See picture below.

Roll each dough strip up "like a fruit roll-up". See picture below.

Place the dough rolls seam side down on the baking vessel, so that all of the rolls are touching one another.

Cover the baking vessel with a towel and let the bread rise for 45 minutes.

Pre-heat your oven while the dough is proofing.

Brush the rolls with butter or duck fat and then bake for about 20 to 25 minutes. The rolls should be set and browned.

This is an optional step, but I like to brush with butter and sprinkle with kosher sea salt as soon as the come out of the oven.
