Hong Kong egg waffles

Gai daan jai: bubble-shaped street waffles, crisp outside and custardy inside

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.

Method

0/5 done
  1. Step 1: Whisk 2 eggs and 2 ⅞ oz caster sugar for 1 minute until frothy. Sift in 4 oz plain flour, ⅔ oz tapioca starch, ½ oz custard powder and 1 ½ tsp baking powder, then whisk in ½ cup evaporated milk, ¼ cup water, 1 tsp vanilla extract and 2 tbsp vegetable oil to a smooth batter, as thick as double cream. Rest for 30 minutes.

    5 min
  2. Step 2: Heat the egg waffle pan on both sides over a medium heat for 3–4 minutes, until a drop of water sizzles on it. Brush both sides lightly with oil.

    4 min
  3. Step 3: Pour about a third of the batter into one side, filling the cups and just covering the flat parts. Close quickly and flip the pan straight away so the batter runs into the top cups.

  4. Step 4: Cook for 2½–3 minutes, flip back and cook for 1½–2 minutes more, until the waffle is golden-brown on both sides and lifts cleanly. Common mistake: opening the pan too early to check; the bubbles collapse and stick. Wait for the full time.

    5 min
  5. Step 5: Lift the waffle onto a wire rack and, while still hot, curl or fold it gently. Leave for 1 minute: it crisps as it cools. Repeat with the rest of the batter and eat within 15 minutes, when the shell is at its crispest.

SakarpadaSweet fried dough diamonds

Sakarpada (shakarpara) are little sweet diamonds of a rich dough made with ghee, milk and sugar, fried until golden and crunchy. They are a Diwali favourite with tea, and the cubes go into bhusu too. They keep for weeks in an air-tight tin.

Yaki onigiriGrilled rice balls

Yaki onigiri (焼きおにぎり) are rice balls grilled until they form a crisp, toasty crust, then brushed with soy sauce glaze. They are eaten all over Japan, at izakaya, at barbecues and from the freezer section, as a snack or with miso soup. The inside stays soft and steamy while the outside crackles. Best eaten hot, straight from the pan. Chef's tip: let the shaped rice balls dry for 10 minutes before they go in the pan. A drier surface forms a better crust and won't stick, and the glaze goes on only at the end so it doesn't burn.

Taiwanese grilled corn

At Raohe and Shilin night markets the grilled-corn stalls are easy to find: look for the queue and the smoky, sweet smell. Cobs are par-cooked, then turned slowly over charcoal while the cook brushes them with a dark glaze of sacha sauce, thick soy paste, garlic and chilli, layer after layer, until the kernels are sticky, slightly charred and deeply savoury. It is eaten hot from a paper sleeve while walking the market. Sacha (shacha) sauce, a Taiwanese barbecue paste, usually contains dried fish and shrimp; vegetarian sacha is sold in Asian shops. Contains soy, wheat and fish. Chef's tip: brush thin coats and turn often; one thick coat burns before the corn chars.
