Ingredients
Method
Prepare the dough
- In a large bowl, mix milk, water, eggs, yeast, sugar, and lemon juice. Gradually add plain flour then salt, mixing with your hand until the dough forms a ball: soft and slightly sticky but not wet. Cover and rest for 1.5 hours.
Shape & fry
- Divide the dough into 8 equal pieces. An easy way is to cut the dough ball in half, roll each half into a ball, then cut each ball in half again. Continue halving until you have 8–10 pieces. Roll each piece into a smooth ball and gently flatten it. Cover and let them rise for 30 minutes.
Make the custard
- Heat the milk and vanilla until steaming.
- Whisk yolks, sugar, plain flour and cornflour until pale in a separate bowl.
- Slowly whisk in hot milk to the bowl and return it all to the pot and cook over medium heat until thick and bubbling.
- Cover with cling film touching the surface and chill until completely cold.
Fill & finish:
- Use a piping bag with a small nozzle to fill each donut with chilled custard. Dust generously with icing sugar (or roll in granulated sugar).
