Preheat the oven to 220°C/ 200°C fan/ gas mark 7/ 425°F
Grease a large baking sheet with butter or use a silicone baking mat
Put the egg into a measuring jug or cup and make up the volume with milk to 125ml. Beat with a fork until the egg is incorporated
Grate the rind from the lemon.
For the Blackberry Scones:
Add the salt and baking powder to the flour and stir well. Grate the butter and rub into the flour until all the butter is incorporated and the mixture looks like fine breadcrumbs
Stir in the sugar and lemon rind. Add the egg/milk mixture, reserving 1 teaspoon (5ml) to glaze the scones, and mix to give a fairly sticky dough
Add the blackberries and mix them in gently with your handsBlackberries are very delicate so don't overmix
Coat your hands in flour and mould the dough into a disc. Place on the baking sheet and flatten with your hands to make a circle of about 17cm (7 ins.) in diameter
Cut the disc into 8 portions and move them apart on the baking sheet. They're sticky so you'll need to use a palette knife or fish slice to move them. Neaten the edges if you like and brush the tops with the extra egg/milk mix
Cook for 10 minutes. Turn the oven down to 200°C/ 180°C fan/ gas mark 6/ 400°F and cook for a further 3-5 minutes until slightly brown on top
Cool on a wire rack, or serve when still warm with butter or cream.
Notes
Ingredients:
Butter - using grated frozen butter makes the mixing in quicker and gives a lighter texture. If you don't have frozen butter, use it straight from the fridge and cut into small pieces before rubbing in.
Storage:
Blackberry Scones, like all scones, are best eaten the day you make them. They will keep for 2-3 days in an airtight container in the fridge, or freeze as soon as they are cool for up to 3 months.
