Preheat your oven to 200°C (400°F) and line a baking tray with parchment paper.
In a large bowl, combine the flour, sugar, dates and lemon rind. Mix well.
450 g self raising flour, 45 g sugar, 140 g medjool dates, 1 lemon
In a separate bowl, whisk together the buttermilk, cream, egg and vanilla. Add to the dry ingredients and mix until the dough just comes together - do not overwork.
150 ml buttermilk, 150 ml pouring cream, 1 egg, 1 teaspoon vanilla extract
Turn the dough out and press into a circle about 1 inch (2.5 cm) thick and approximately 20 cm wide.
Cut into 8 wedges and place onto the lined baking tray, leaving space between each piece.
Brush the tops with a little extra cream, then refrigerate for 15 minutes.
Bake for 12–15 minutes, or until golden and well risen. Allow to cool slightly before serving with jam and cream.
