Add granulated sugar and the instant dry yeast to the warm (95F-110F) water. Stir until dissolved and set aside until the mixture starts to foam on the surface.
¾ cup Warm Water, 1 tablespoon Instant Dry Yeast, 1 tablespoon Granulated Sugar
Prepare the eggs for dough by cracking them into a small bowl. Use a fork to whisk the eggs, just until liquid.
2 large Eggs
Place the flour, salt, granulated sugar, and softened butter into the stand mixer. Mix on low-medium until the butter has turned into a fine crumb.
5 cups All Purpose Flour, 2 teaspoon Salt, 3 tablespoon Granulated Sugar, ⅓ cup Unsalted Butter
Pour the warm (95F-110F) milk into the flour mixture. Also add in, the foamy yeast mixture, and the whisked eggs. Mix on low until all ingredients have combined.
¾ cup Warm Milk
Turn up the speed of the mixer to medium and mix for 3-4 minutes or until the dough comes together in a ball. Pinch the dough and it should be tacky, and not too sticky.
Transfer the brioche sub roll dough to a very lightly floured, clean counter. Use your hand to fold the dough onto itself (knead) 3-4 time, to shape it into a tighter larger ball. Place in a large bowl and cover with a damp clean linen towel. Rest the dough for 20 minutes.
