Proof the yeast and measure the flour:
In a small bowl, place 1/4 cup warm water and sprinkle the yeast over it. Let it sit until dissolved and creamy, about 5 minutes.
Meanwhile, in a large mixing bowl, combine 3 cups (387g) flour and salt.

Melt the butter, then add the milk, honey, and egg:
In a small saucepan, melt 4 tablespoons butter over medium-low heat. Whisk in the honey and buttermilk, and heat just until warm to the touch (do not boil). Remove from heat and whisk in the egg.

Make the dough:
Add the water and yeast mixture to the flour, along with the buttermilk mixture. Mix with a wooden spoon until the dough just comes together. At first it will be quite sticky. If needed, add the remaining 1/2 cup (64g) flour, bit by bit. Resist the temptation to add a lot of flour; you want a soft dough that’s still kneadable.
Transfer to a clean counter and gently knead by hand until smooth and supple, about 5 minutes. I don’t need to flour my counter—if the dough sticks, it needs more flour. Place the dough in a large, greased bowl, cover, and let rise on your counter until doubled in bulk, 1 to 2 hours.

Preheat the oven to 350°F:
Position racks in the upper and lower thirds and line two baking sheets with parchment.
Divide the dough and prep for baking:
Divide the dough into 12 equal pieces and let them rest on a lightly floured surface for 10 minutes.
Melt the remaining 4 tablespoons of butter. Divide the pepperoni into 12 roughly equal piles.

Form the rolls, then let them rise:
Take a piece of dough and pat it into a square roughly 4 to 5 inches across. Imperfection is totally acceptable here, and in fact slightly preferable. Shingle the pepperoni slices over the square, leaving a 1/4-inch border around the dough. Roll up the dough and firmly pinch the bottom seam to seal. Place it seam-side-down on the baking sheet. Repeat with the remaining dough. You’ll wind up with 6 rolls per sheet.
Brush the rolls with half of the melted butter. Cover each baking sheet with a clean dish towel and let rise for 30 minutes. The rolls will not puff up visibly.

Bake the rolls and serve:
Bake until lightly browned, 30 to 40 minutes, rotating the sheets from top to bottom and back to front halfway through baking. Immediately after removing from the oven, brush with the remaining butter—you may need to rewarm the butter slightly before brushing.
Serve warm or at room temperature. Keep the cooled rolls at room temperature in a tightly sealed plastic bag or wrapped in plastic wrap for up to 3 days.
To freeze the baked rolls, cool completely. Wrap each roll in plastic wrap, then in foil, and then pop the individually wrapped rolls in a zip top storage bag. Freeze for up to 1 month. Thaw on the counter and, for the best eating experience, warm in a microwave for 15 to 30 seconds before eating.
