Light Brioche Buns (good for hamburgers)
from https://cooking.nytimes.com/

This brioche is lighter than the traditional kind. It’s still fluffy and moist, but not quite as eggy and rich. Even the color is a bit lighter. It is the perfect vessel for a juicy burger and would be great for sandwiches too!
1 cup warm water
3 tablespoons warm milk
2 teaspoons active dry yeast
2 1/2 tablespoons sugar
2 large eggs
3 cups bread flour
1/3 cup all-purpose flour
1 1/2 teaspoons salt
2 1/2 tablespoons unsalted butter, softened
sesame seeds (optional)
In a glass measuring cup, combine 1 cup warm water, the milk, yeast and sugar. Let stand until foamy, about 5 minutes. Meanwhile, beat 1 egg.
In a large bowl, whisk flours with salt. Add butter and rub into flour between your fingers, making crumbs. Using a dough scraper, stir in yeast mixture and beaten egg until a dough forms. Scrape dough onto clean, unfloured counter and knead, scooping dough up, slapping it on counter and turning it, until smooth and elastic, 8 to 10 minutes.
Shape dough into a ball and return it to bowl. Cover bowl with plastic wrap and let rise in a warm place until doubled in bulk, 1 to 2 hours.
*Giving your dough enough time to rise is crucial in bread baking. Rise times will vary, so be patient. Remember to watch your dough and not the clock!
Line a baking sheet with parchment paper. Using dough scraper, divide dough into 8 equal parts. Gently roll each into a ball and arrange 2 to 3 inches apart on baking sheet. [Gently flatten each piece of dough like a pancake. Pull up each side pinching it together in the center. Repeat until the ball is sealed. Flip the ball over (seam side down).] Cover loosely with a clean kitchen towel and let buns rise in a warm place for 1 to 2 hours.
Set a large shallow pan of water on oven floor. Preheat oven to 400 degrees with rack in center. Beat remaining egg with 1 tablespoon water and brush some on top of buns. At this point, you could add sesame seeds to the top of your rolls if desired.
Bake, turning sheet halfway through baking, until tops are golden brown, about 15 minutes. Transfer to a rack to cool completely.
Yield: 8 buns
