Steps:

• Mix all ingredients well and let sit covered for 10 minutes. Knead for 5 to 8 minutes and tip onto the counter dusted lightly with flour.
• Stretch the dough into a rectangular shape and fold it letter-style top to bottom and side to side.
• Place in an oiled straight-sided container and cover with plastic wrap. After 15 minutes, stretch and fold the dough again and return to the container.
• When the dough is twice it's initial size, remove from bowl and on lightly floured surface, divide into 10 pieces weighing 85 g each (approximately).
• Round each piece on the counter by pressing down as you circulate your hand in a counter-clockwise direction until the piece is a smooth ball.
• Press each dough ball flat with floured hands, repeating as needed over the next 10 minutes and place on a pan or sheet lined with parchment paper.
• Preheat oven to 375°F.
• Cover with oiled plastic and let proof for about 30 minutes or so until the dough has risen about 1 1/2 times it's volume.
• Brush with egg wash if desired and bake for 7 minutes.
• Rotate pan and bake for 7 more minutes until 190F internally.
• Cool buns on a rack until room temperature.

Steps:

• In a food processor grate the potatoes. Line a sieve with cheesecloth and transfer potatoes to the sieve. Set sieve over a bowl, twist cheesecloth into a pouch, squeezing out some moisture. Let mixture drain for 15 minutes. After 15 minutes, pour off liquid from the bowl but leave the white potato starch that settles in the bottom of the bowl.
• To that starch add shallots, eggs, flour, 1-1/2 teaspoons of salt and freshly ground pepper. Return drained potatoes to this mixture and toss to combine.
• Preheat oven to 200 degrees. Line a baking pan with paper towels. When you are ready to eat, in a large skillet heat 1/4 inch of oil over medium high heat until hot. Drop heaping tablespoonfuls of potato mixture and cook for 3 to 4 minutes a side; latkes should be golden and crisp on both sides. Eat right away or keep warm in oven. Serve with applesauce or sour cream or cottage cheese mixed with sour cream.
