In a food processor, blitz the biscuits to a fine crumb (or place in a food bag and crush with a rolling pin). Tip into a bowl and pour over the melted butter; mix well.Step 2
Tip the biscuit mixture into a 23 cm loose-bottomed tart tin and spread out evenly to fill the base and sides, pressing down firmly with clean fingers or the back of a spoon. Chill for 20 mins.Step 3
Meanwhile, combine the cordial, lemon zest and juice in a jug.Step 4
Combine the cream and sugar in a saucepan over a low heat and bring just to the boil, stirring until the sugar dissolves. Remove from the heat and leave to stand for 5 mins to thicken slightly. Stir in the lemon-elderflower mixture, then pour the filling into the chilled case. Chill for at least 6 hrs or ideally overnight, until set. Decorate with extra lemon zest before serving.
