Preheat the oven to fan assisted 180C / 200C / 400C / gas 6.

Mix together flour, sugar and salt and place in a food processor. Add in the cold butter and whizz until it reaches a breadcrumb consistency.

Transfer the mixture into a bowl and stir in the lemon zest, lemon juice and ground cardamom. Make a well in the centre, pour in the milk and mix into a dough. Knead for a minute to combine all the ingredients.

Then transfer the dough onto a lightly floured surface and pat out till the mixture is about 2cm thick. Cut out 6cm rounds using a pastry cutter. You might need to reform the trimming and cut out a few more.

Place the scones onto a lightly flowered baking tray, brush them with some milk and bake for 18-20 minutes, until golden.

Serve with some clotted cream and jam.
