For high tea or dessert try this shortcake full of pistachio and citrus flavours, delicious with peaches and rhubarb. Serve with a dollop of lightly whipped cream - naughty but scrummy. I used the rhubarb from the garden which got out of control over the holiday. It adds a nice tartness to the sweet peaches.
Into a large bowl place the flour, baking powder, sugar, lime and orange zest and pistachios. Add the butter. Using your fingers break it down until it forms coarse breadcrumbs.
Place the sour cream in a small bowl and beat in the egg. Pour straight into the flour, mixing gently to form a soft dough. On a lightly floured bench flatten the dough to 2cm high. Cut circles 5cm in diameter, and lay on a baking tray.
Bake for 20 minutes until cooked and slightly golden. Remove and cool.
To make filling: Place 2cm water and the sugar in a pot. Bring to a simmer and dissolve sugar. Add peaches and cook for 5 minutes. Then add rhubarb and cook for another 5 minutes. Remove and cool.
Split the shortcake in half. Cover the base with cream and fruit. Place the top on and sprinkle a little extra sugar.
