Potato Burger Buns

Potato Burger Buns, variation from the main recipe Potato Dinner Rolls from Bread Illustrated. Uses a cup of mashed Russet potatoes, with some of the potato water from boiling the potatoes. 

I top a few of the buns with a sprinkling of sesame seeds and the rest without.The buns baked to a deep golden brown, thanks to the egg wash.

The baked buns are soft but not fluffy soft as I thought they would be. 

Use the burger buns to make Egg Banjo, for our lunch.

Potato Dinner Rolls
(Bread Illustrated, America's Test Kitchen)
1 large russet potato (10 ounces) peeled and cut into 1-inch pieces
2 tablespoons unsalted butter, cut into 4 pieces
2-1/4 cups (12-1/3 ounces) bread flour
2 teaspoon or rapid-rise yeast
1 teaspoon salt
1 large egg, room temperature
1 tablespoon sugar

1 large egg, lightly beaten with 1 tablespoon water and pinch of salt

  1. Place potato in medium saucepan and cover with 1 inch cold water. Bring to boil over high heat, then reduce to simmer and cook until potatoes is just tender (paring knife can be slipped in and out of potato with little resistance), 8 to 10 minutes.
  2. Transfer 5 tablespoons (2-1/2 ounces) potato cooking water to 4-cup liquid measuring cup and let cool completely ; drain potatoes. Return potatoes to now-empty saucepan and place over low heat. Cook, shaking saucepan occasionally, until any surface moisture has evaporated, about 30 seconds. Off heat, process potatoes through ricer or food mill or mash well with potato masher. Measure 1 cup very firmly packed potatoes (8 ounces) and transfer to separate bowl. Stir in butter until melted and let mixture cool completely before using. Discard remaining mashed potatoes or save for another use.
  3. Whisk flour, yeast, and salt together in bowl of stand mixer. Whisk egg and sugar into potato cooking water until sugar has dissolved. Add mashed potato mixture to flour mixture and mix with your hands until combined (some large lumps are OK). Using dough hook on low speed, slowly add cooking water mixture and mix until cohesive dough starts to form and no dry flour remains, about 2 minutes, scraping down bowl as needed. Increase speed to medium-low and knead until dough is smooth and elastic and clears sides of bowl but sticks to bottom, about 8 minutes.
  4. Transfer dough to lightly floured counter and knead by hand to form smooth, round ball, about 30 seconds. Place dough seam side down in lightly greased large bowl or container, cover tightly with plastic wrap, and let rise until doubled in size, 30 minutes to 1 hour.
  5. Line rimmed baking sheet with parchment paper. Press down on dough to deflate. Transfer dough to clean counter and stretch into even 12-inch log. Cut log into 12 equal piees (about 2 ounces each) and cover loosely with greased plastic.
  6. Working with 1 piece of dough at a time (keep remaining pieces covered), form into rough ball by stretching dough around your thumbs and pinching edges together so that top is smooth. Place ball seam side down on clean counter, and, using your cupped hand, drag in small circles until dough feels taut and round.
  7. Arrange dough balls seam side down on prepared sheet, spaced about 1-1/2 inches apart. Cover loosely with greased plastic and let rise until nearly doubled in size and dough springs back minimally when poked gently with your knuckle, 30 minutes to 1 hour. (Unrisen rolls can be refrigerated for at least 8 hours or up to 16 hours ; let rolls sit at room temperature for 1 hour before baking).
  8. Adjust oven rack to upper-middle position and heat oven to 425 degrees. Gently brush rolls with egg mixture and bake until golden brown, 12 to 14 minutes, rotating sheet halfway through baking. Transfer rolls to wire rack and let cool for 15 minutes. Serve warm or at room temperature.

For Potato Burger Buns :
Divide dough into 9 pieces (about 2-3/4 ounces each) and shape into smooth, taut rounds as directed in step 6. Let rounds rest for 15 minutes, then press into 3-1/2 inch disks of even thickness. Arrange disks on 2 parchment paper-line rimmed baking sheets and let rise as directed in step 7. Sprinkle rolls with 1 tablespoon sesame seeds, if desired, and bake on upper-middle and middle racks until rolls are deep golden brown, 15 to 18 minutes, switching, and rotating sheets halfway through baking. Makes 9 burger buns.
