Equipment

  • 1 mould 21 x 21 cm (8x8'')

Ingredients

  • 120 g cornstarch (4 ¼ oz)
  • 180 g white sugar ((6 ½ oz))
  • 1000 ml plant-based milk unsweetened ((4 cups))
  • 1 vanilla pod halved
  • 1 pinch saffron or turmeric
  • 120 g vegan margarine or butter (4 ¼ oz)
  • 1 rectangular puff pastry sheet 42 x 21 cm (16 x 8'')
  • 100 g powdered sugar
  • 2 tablespoon plant based milk

Instructions

  • For the custard, place starch and sugar into a large saucepan and mix.
  • Little by little add in milk while mixing vigorously so that no lumps form.
  • Stir in saffron (or turmeric) and vanilla.
  • Bring the mixture to a boil while constantly stirring.
  • Once the mixture is thick and creamy remove from heat.
  • Add in butter and mix until combined.
  • Cover with plastic wrap and allow to cool for at least 1 hour (cool in an ice bath if you want to speed up the process).
  • Preheat the oven to 200 °C (400 °F).
  • Unroll puff-pastry onto a sheet of baking paper and cut it into two 21x21 cm (8x8'') squares.
  • Using a fork, prick the puff pastry all over so that it doesn't puff up too much while baking.
  • Cover the squares with another layer of baking paper.
  • Lay a baking tray on top and bake for 12 minutes until golden and crispy. In case the pastry is still slightly pale bake it for another 2-3 minutes.
  • Take off the oven and allow to cool.
  • To assemble, line a 21 x 21 cm (8x8'') mould with baking paper.
  • Stir custard until creamy and place into a piping bag.
  • Set 1 layer of puff-pastry into the mould.
  • Pipe custard on top creating an even layer.
  • Top with the second layer of puff-pastry and press lightly.
  • For the topping, in a bowl combine powdered sugar and milk. Pour over the pastry and spread evenly.
  • Set in the fridge for at least 30 min or until the sugar glaze is dry.
  • Cut the pastry into 8-10 custard slices and serve right away.
