Vanilla slice

Custard slice between puff pastry with passionfruit icing

The vanilla slice, or snot block as Aussie kids call it, is the country bakery's pride; towns like Ouyen in north-west Victoria even hold a yearly competition for the best one. A thick, wobbly vanilla custard is set between two sheets of crisp puff pastry and topped with white or passionfruit icing. It needs a few hours to set but is easy. A common mistake is a soft custard that oozes when cut; it must boil for a full minute to thicken properly. Chef's tip: prick and weigh the pastry down with a tray while baking so it stays flat and thin.

Method

0/7 done
  1. Step 1: Heat the oven to 400°F (350°F fan). Lay each 2 sheets ready-rolled puff pastry sheet on a lined tray, prick all over, cover with baking paper and a second tray to keep it flat, and bake for 15 minutes. Remove the top tray and bake 5–8 minutes more until golden and crisp. Cool, and trim both to fit a 23 cm square tin.

    25 min
  2. Step 2: Line the tin with baking paper, leaving an overhang, and lay one pastry sheet in the base.

    2 min
  3. Step 3: Whisk 2 ⅛ oz custard powder, 1 ¾ oz cornflour and 5 ½ oz caster sugar with a little of the 3 ¼ cups full-fat milk to a smooth paste, then whisk in 4 egg yolks.

    3 min
  4. Step 4: Heat the rest of the milk and 1 cup double cream until steaming, whisk into the paste, then return to the pan. Whisk over a medium heat until it boils and becomes very thick, then keep whisking for 1 full minute. Take off the heat and beat in 1 ⅜ oz butter and 2 tsp vanilla extract.

    10 min
  5. Step 5: Pour the hot custard over the pastry base, smooth it and lay the second sheet on top, smooth side up, pressing gently.

    3 min
  6. Step 6: Mix 7 oz icing sugar, 2 tbsp passionfruit pulp and ⅓ oz butter to a thick, spreadable icing and spread over the top. Chill for at least 4 hours or overnight.

    240 min
  7. Step 7: Lift out by the paper and cut into 12 slices with a sharp serrated knife, wiping it between cuts.

Moreton Bay bugsSlipper lobster with garlic butter

Moreton Bay bugs are the flat, shovel-nosed slipper lobsters caught off the Queensland coast around Brisbane and the Sunshine Coast, and for Queenslanders they are a summer treat, split and grilled at the beach house. The tail meat is sweet and rich, somewhere between lobster and prawn. Buy them raw, frozen or fresh, from a fishmonger and ask them to halve them if you like. A common mistake is overcooking, which makes the meat rubbery; it is ready the moment it turns white. Chef's tip: grill flesh side down first to mark it, then turn and baste in the shell.

Reform tortaWalnut meringue chocolate cake

Belgrade pastry shops have sold reform torta since the early twentieth century, and it is still the cake Serbian families bring out for birthdays, weddings and the slava. Three thin layers of walnut meringue, crisp at the edge and chewy inside, are stacked with a dense chocolate butter cream made with egg yolks cooked over steam until thick. It is very rich, so cut thin slices and serve with strong coffee. The usual slip is beating the butter into a chocolate mixture that is still warm, which melts it and splits the cream; let it cool to room temperature first. Chef's tip: assemble the cake the day before; overnight in the fridge the meringue softens a little and the cake slices cleanly with a hot knife.

Ma'amoulDate and walnut butter pastries

Ma'amoul are delicate shortbread-like pastries made for Eid and Easter across the Middle East. A soft, rose-scented butter dough is wrapped around a filling of dates, walnuts, almonds and pistachios cooked with cinnamon, marked with a fork, baked pale and dusted with icing sugar. Makes 35; they keep well in a tin.
