Almond pastry shell filled with an eggless, agar-set chocolate mousse

0/11 done
  1. Step 1: Mix 8 oz plain flour, 5 ½ oz almonds, 3 ½ oz unsalted butter, 1 ¾ oz caster sugar and 2 tbsp milk to a soft dough.

  2. Step 2: Press the dough with your hands over the base and up the sides of a greased 20 cm loose-bottomed flan tin. Freeze for 30 minutes.

    30 min
  3. Step 3: Heat the oven to 350°F (325°F fan). Bake the pastry case for 15 minutes, until golden. Let it cool, then lift it out of the tin.

    15 min
  4. Step 4: Soak ⅛ oz agar-agar strands in ¾ cup water for 15 minutes, then heat gently, stirring, until it dissolves completely.

    20 min
  5. Step 5: Whisk 1 ¼ cups cold milk, 1 ¾ oz dark chocolate, 4 tbsp cocoa powder, 1 tsp custard powder, ½ tsp vanilla essence and 3 tbsp sugar together in a pan while the milk is still cold.

  6. Step 6: Bring to the boil over a medium heat, stirring all the time, until it thickens.

    5 min
  7. Step 7: Add the agar mixture and boil for 2 minutes more, stirring, until thick. Let it cool until just warm.

    2 min
  8. Step 8: Mix 3 ½ oz fresh cream with 1 tsp vanilla essence and fold it gently into the chocolate mixture.

  9. Step 9: Spoon the mousse into the pastry case and refrigerate until set, about 2 hours.

    120 min
  10. Step 10: For the curls, melt 7 oz plain chocolate and spread it thinly on a marble slab or a clean, cold tray. When just set, drag a sharp knife across it at a slight angle so the chocolate curls up.

    10 min
  11. Step 11: Decorate the tart with the chocolate curls and serve chilled.

Kartoshka cakeCocoa and cake crumb truffles

Soviet cafés and school canteens sold these knobbly brown 'potatoes' for a few kopecks, and they began as a thrifty way to use up sponge and biscuit trimmings at the bakery. Crumbs are bound with butter and sweetened condensed milk, flavoured with cocoa and vanilla, shaped into little potatoes, rolled in cocoa and finished with two dabs of pale butter cream for the sprouts. They are fudgy and dense like a brownie truffle, need no oven, and children love making them. Traditional bakers added a spoonful of rum, an optional extra for adult batches only; this version is alcohol-free with vanilla. The usual slip is coarse crumbs, which make the potatoes crack, so blitz them as fine as sand. Chef's tip: chill the shaped potatoes for at least 20 minutes so they hold their shape and slice cleanly.

Undu walaluFried urad dal rings in treacle

Walalu means bangles, and these dark, sticky rings of fried urad dal soaked in kithul treacle are a sweet that Sinhala families bring out for Avurudu and for special almsgivings, often made in large batches by an aunt known for her steady hand. A thick, fluffy paste of ground black gram is piped into loops and fried until crisp, then plunged straight into warm treacle, so the rings stay crunchy on the outside while drinking up the syrup. They taste a little like a darker, smokier jalebi, with a toffee finish from the palm treacle. Watery batter is what ruins them; it spreads into flat blobs, so grind the soaked dal with as little water as possible and beat it until light. This recipe uses no asafoetida, so it is naturally gluten free. Chef's tip: pipe the rings onto small squares of baking paper and lower them into the oil paper and all; the paper peels away in seconds.

Apple & pear puree

A smooth, naturally sweet puree of gently stewed apple and pear, one of the first foods for babies of 4–8 months. The fruit cooks in a little unsweetened apple juice, so nothing else is needed. Serve it lukewarm; any leftover keeps covered in the fridge for a day, or freezes well in small pots.
