Try to be confident and bring the pastry together as quickly as you can. Don’t knead it too much or the heat from your hands will melt the butter. A good tip is to hold your hands under cold running water beforehand to make them as cold as possible. That way you’ll end up with a delicate, flaky pastry every time.
- Sieve the flour from a height on to a clean work surface.
- Using your hands, work the cubes of butter into the flour and sugar by rubbing your thumbs against your fingers until you end up with a fine, crumbly mixture. This is the point where you can spike the mixture with interesting flavours, so mix in your lemon zest.
- Add the milk to the mixture and gently work it together till you have a ball of dough. Flour it lightly. Don’t work the pastry too much at this stage or it will become elastic and chewy, not crumbly and short.
- Flour your work surface and place the dough on top.
- Pat it into a flat round, flour it lightly, wrap it in clingfilm and put it into the fridge to rest for at least half an hour.
