Hong Kong paper-wrapped sponge cake
Hong Kong bakery windows line up these tall, golden cylinders, each in its own band of greaseproof paper, and they sell out early as a breakfast with a glass of milk tea or an after-school snack. Known in Cantonese as zhi bao dan gao, they are close to a chiffon cake: oil and milk keep the crumb soft and moist, and whisked egg whites make it light and bouncy. You peel the paper off as you eat, and the thin outer crust is the best bit. Greasing the paper is a frequent mistake; the batter needs a dry surface to grip and climb, otherwise the sponges slump. Chef's tip: stand the paper cups in a deep muffin tin or ramekins so they keep their shape, and fill them only three-quarters full.
