We call it, Salted egg yolk lava bun. Why lava? Because when you split the bun, the yellow filling which comes from salted egg yolk is melted just like a mountain’s lava.
You can make this salted egg yolk as a breakfast to-go menu or just as a snack when your family gathers around. Serve it inside a round dim sum basket to bring an ancient Chinese vibe and don’t forget a glass of hot tea.
