Instructions
Proof Yeast: In a small bowl; dissolve yeast, warm water, and sugar. Let sit for 5-10 minutes until frothy.
Mix Dough: Combine milk, mashed potatoes, butter, sugar, egg, and salt. Add yeast mixture. Gradually mix in flour until a soft dough forms. Knead for 6-8 minutes until smooth. Add more flour a tablespoon at a time until dough is not sticky but still slightly tacky.
First Rise: Cover and let rise 45-60 minutes, until doubled in size.
Shape: Divide dough into 12 pieces. Shape into balls, flatten, and place in prepared wide-mouth canning rings.
Second Rise: Let rise for 10-15 minutes. Preheat oven to 375°F.
Apply Wash and Topping: Whisk egg wash together and brush tops of buns with a pastry brush. Sprinkle sesame seeds (if using).
Bake and Cool: Bake for 11-14 minutes, turning halfway. Remove from rings and cool completely before slicing.
