- 200 grams sourdough discard (or bubbly sourdough starter, see recipe notes, heaping 3/4 cup)
- 65 grams granulated sugar (about 1/3 cup)
- 120 grams warm water (about 1/2 cup)
- 10 grams instant yeast (about 1 Tablespoon, see recipe notes)
- 113 grams melted unsalted butter (8 Tablespoons or 1 stick)

Instructions
- 1
To the bowl of a stand mixer add the room temperature mashed potato, sourdough discard, warm water, granulated sugar, instant yeast, melted butter, eggs and salt. Add most of the flour, reserving about a cup to add as needed. Mix until completely combined and add the rest of the flour a little bit at a time until the dough is tacky (not super sticky) and pulls away from the sides of the bowl. If the dough is overly sticky, add a little more flour. Depending on how hydrated your mashed potatoes are, you may need more or less flour.

Mix the dough for 8-10 minutes until smooth. Alternatively you can knead the dough by hand for 10-15 minutes.
- 3
Cover the dough and let rise for about 1-2 hours until doubled in size.
- 4
Lightly grease a 9 by 13 inch pan and an 8 by 8 pan. Alternatively you could line a large baking sheet with parchment paper and place dough balls on the baking sheet.

Once the dough has risen, cut and separate into 24 pieces. Take each piece of dough and pull/pinch up the sides until it forms a ball. Roll the ball on the counter using your hand in a cupping shape (see video here) to seal the balls and create tension for the roll to rise. Nestle together in the pan or on the baking sheet. Cover and let rise until puffy, touching and almost doubled in size.

Preheat oven to 350ºF. Once the oven is pre-heated, bake the rolls for about 22-25 minutes until starting to brown on top and baked all the way through. Spread some melted butter on top of the warm rolls if desired and enjoy!
