In a stand mixer bowl, combine warm water, instant dry yeast, granulated sugar, olive oil, salt, and all-purpose flour. Knead on low speed until combined, then increase to medium and knead until a smooth dough forms, about 6-8 minutes.

Place the dough in an oiled bowl, cover, and let rise in a warm place until doubled in size, about 1 hour.

Punch down the dough, divide it into 12 pieces, shape into rolls, and place on a parchment-lined baking sheet. Cover and let rise for 30 minutes.

Preheat the oven to 400°F (200°C). Mix egg and water for an egg wash and brush over the rolls. Optionally score the tops of the rolls.

Bake for 18-20 minutes, adding ice cubes to the oven for steam. Remove and brush with melted butter before serving.
