For the rolls:
- 1/2 cup canned pineapple juice (room temperature)
- 1/2 cup warm milk (100 – 110°F)
- 4 tablespoons unsalted butter, melted and slightly cooled
- 2 whole eggs, lightly beaten
- 6 tablespoons granulated sugar
- 1 1/2 teaspoons fine salt
- 2 1/4 teaspoons (1 packet) instant yeast
- 4 1/2 cups (20 ounces) bread flour
- 1 large egg
- Combine the pineapple juice, milk, melted butter, eggs, sugar, salt, and yeast in the bowl of a stand mixer. Add 2 cups of the flour and stir with a wooden spoon until the dough forms a rough, shaggy mass. Attach the dough hook to the mixer and turn to medium-low speed. Gradually add the remaining flour, kneading until a dough begins to form. Continue kneading on medium-high speed for 4 to 5 minutes, until a soft and smooth ball of dough forms.
- Place the dough in a clean bowl. Cover with plastic wrap. Let rise until puffy and doubled in size, about 1 hour.
- Spray a 13x9-inch baking pan with cooking spray. Gently deflate the dough. Use a bench scraper or knife to divide the dough into 15 equal pieces. Shape each piece into a ball and place in the prepared pan.
- In a small bowl combine the egg with 2 tablespoons of water. Brush all over the rolls. Cover with plastic wrap and let rise again until doubled in size, about 30 minutes.
- Meanwhile, preheat the oven to 375°F.
- Bake the rolls for 20 minutes, or until golden brown. Serve warm.
