175 g plain white flour
125 g butter (unsalted) (cold, cubed)
50 g unrefined golden caster sugar
1 orange zest
125 g icing sugar (filling)
100 g butter (unsalted) (filling)
0.25 tsp strawberry flavouring (filling)
2 tbsp strawberry jam (filling)
1. Place the flour and butter in the bowl of a food processor and pulse until the mixture resembles breadcrumbs. Alternatively rub the butter into the flour by hand.
2. Add the sugar and orange zest and pulse again or mix with a spoon until the mixture starts to get sticky. Tip the dough onto a lightly floured surface and lightly knead so that the dough comes together to form a smooth ball. Chill for 10 minutes.
3. Preheat the oven to 180°C (160°C fan, gas mark 4). Line 2 baking sheets with baking paper.
4. Roll the dough out onto a lightly floured surface to the thickness of about 5mm, pressing it together if it cracks a bit. Cut out with 16 x 6cm/5cm cutters, re-rolling the dough until it has all been used. Cut out a smaller round shape out of half the rounds.
5. Lay the biscuits on the baking sheets and bake for 10-12 minutes until pale golden. Remove, transfer to a wire rack and leave until cold.
6. Place the icing sugar and strawberry flavouring into a large bowl and mix in 1 tbsp warm water. Add the butter and mix together with a blender or whisk until light and fluffy. Spread the icing over the full biscuits and top with a thin layer of jam then the remaining biscuits. Leave to set for 30 minutes and then enjoy.
