How do sesame seeds stick to buns?

Question

i just wanted to know because a friend of mine said it was the small surface area against large surface area and i didn't think that could just be it.

Answer 1

its the moisture on the surface of the buns. alot of the time before baking the buns they are brushed with either milk or egg wash and this helps the sesame seeds stick as well.

Answer 2

Well, you can wet the bun with whatever you want then roll it in the sesame seeds:)

Answer 3

They put an egg wash on them and then sprinkle on the seeds. amazing innit? x.x.x.x.x.

Answer 4

You can use an egg wash of whole or whites, lightly beaten - or brush some heavy cream on top before baking

Answer 5

Answer 6

Egg wash

Answer 7

sesame seeds stick to an invisible layer of egg whites burshed on at the end of the baking time
