Kittencal's Sub Sandwich Buns Recipe

How to Make Kittencal's Sub Sandwich Buns

1. Prepare a heavy-duty stand mixer fitted with a dough hook.
2. Add 3 1/2 cups (455g) all-purpose flour to the mixer bowl.
3. Melt 1/2 cup (113g) shortening in the microwave.
4. Add the melted shortening to the flour in the bowl.
5. In a separate measuring cup, combine 1 cup (240ml) milk, 4 tablespoons (50g) granulated sugar, and 1 teaspoon (5g) salt.
6. Heat the milk mixture in the microwave until warm (around 105-115°F), stirring to dissolve the sugar and salt.
7. Pour the warm milk mixture into the bowl with the flour and shortening.
8. Cover the bowl with a clean kitchen towel to keep the ingredients warm.
9. In a small bowl, proof 2 1/4 teaspoons (7g) active dry yeast in 3/4 cup (177ml) warm water (105-115°F) with 1 teaspoon (4g) sugar for 8-10 minutes, or until foamy.
10. Add the proofed yeast mixture to the mixer bowl. Knead with the dough hook for 3-4 minutes, then gradually add more flour (about 1/2 cup at a time) until a soft, slightly sticky dough forms. Continue kneading for another 8 minutes until the dough is smooth and elastic.
11. Lightly flour a clean work surface.
12. Turn the dough out onto the floured surface and let it rest, covered with a clean kitchen towel, for 5-10 minutes.
13. Grease a large bowl with cooking spray or oil. Place the dough in the bowl, turning to coat. Cover and let rise in a warm place for 50-60 minutes, or until doubled in size.
14. Gently punch down the dough.
15. Divide the dough into 8 equal pieces. Shape each piece into a large ball.
16. Let the dough balls rest for about 4 minutes.
17. Shape each dough ball into a long oval, approximately 8 inches in length (adjust according to desired bun size).
18. Sprinkle a large baking sheet with cornmeal or lightly grease it with cooking spray.
19. Place the shaped dough pieces onto the prepared baking sheet.
20. Cover the baking sheet loosely with plastic wrap and let the buns rise for another 25 minutes, or until doubled in size.
21. Preheat oven to 375°F (190°C).
22. Bake for 22-25 minutes, or until the buns are a deep golden brown.
23. (Optional) For an extra glossy finish: In a small bowl, whisk together 1 egg white and 1 teaspoon of cold water. Brush the mixture over the buns before baking. Sprinkle with sesame seeds, if desired.
