Saving on Eggs
> saw on old lady bring her own egg to the jian bing guozi seller to save money
Sam is talking about 煎饼果子 (pictures). They’re made by spreading a basic batter on a hot plate, and cooking an egg on top, and then spreading a sauce on it. The total cost (including the price of the egg), is usually 1-3 RMB (depending where you are in China). Eggs generally cost much less than 1 RMB each.
