Hong Kong egg waffles
Gai daan jai, 'little eggs', are the honeycomb sheets of puffed bubbles sold from street carts in Mong Kok and Sham Shui Po since the 1950s, handed over in a paper bag to be pulled apart bubble by bubble while you walk. A good one is crisp and thin on the outside and soft, almost hollow, in the middle, with the smell of egg, vanilla and evaporated milk. You need the special egg waffle pan with round cups. Chef's tip: rest the batter for at least 30 minutes; it bakes up lighter and the bubbles fill evenly.
