In a medium mixing bowl, combine warm water, yeast, corn syrup, and melted butter. Let sit for 5 minutes until frothy.

Add salt and 3 cups of flour. Mix well, gradually add remaining flour until dough is soft and elastic.

Knead the dough for 10 minutes either by hand or using a stand mixer.

Shape the dough into a ball, place in a greased bowl, cover, and let rise for 45 minutes.

Divide the risen dough into 6-8 pieces. Roll each into a smooth ball and place on parchment-lined baking sheet. Cover and let rise another 45 minutes.

Preheat oven to 425°F. Bring 4 cups water and 3 tablespoons baking soda to a boil.

Boil each roll for 30 seconds, flip, and boil another 30 seconds. Remove with slotted spoon and place on baking sheet.

Use a sharp knife to cut an X on top of each roll. Brush with egg white and sprinkle with salt.

Bake for 15 minutes until deep golden brown. Cool slightly before serving.
