Hot Dog Potato Bun

Hot dogs are not easily available here, I use this tin frankfurts which serves the same purpose. Some hotdogs are thick. I slice this can hot dog into half length wise.

Hot Dog Potato Bun

Ingredient

2 1/2 cups plain flour

2 tbsp melted butter2 tbsp sugar

1/2 cup mashed potatoes (boil potatoes beforehand. Mashed and cooled)
1 egg
1/2 cup warm water
2 tsp instant dry yeast
1/2 tsp salt

To glaze bun
1 egg yolk
2 tbsp milk

Sesame seeds

I use bread machine for dough processing

Dissolve yeast in the warm water and set aside. Put into bread machine; flour, mashed potatoes, butter, sugar, egg, butter, salt and the yeast dissolved in warm water. Set bread machine in dough mode and leave it to complete its cycle.
When dough is ready, remove from bread machine onto flour dusted surface. Divide dough into 12 portions. Roll each portion out into long bun shape, place hotdog in the middle of the dough and wrap the dough around it. Place long bun on a greased baking tray. Finish the remaining dough and place each alongside each other and leave to prove for 30 minutes. Egg wash the bun and sprinkle with sesame seeds. Bake in a 220 c oven for 20 minutes. Remove and cool off alittle before serving.

Sometimes it is not easy to make these long buns in the same length. I wonder anyone has some tips for it?
