Rhubarb Vodka Martini

• 2 rhubarb stalks, trimmed and cut into 8 cm (3 inch) lengths
• 1 tablespoon caster (superfine) sugar
• 1

Put the rhubarb into a stainless-steel saucepan with the sugar and 150 ml (5 fl oz) of water. Bring to the boil, then turn the heat down to a simmer and cook until the rhubarb has fallen apart, about 15 minutes. Stir in the vanilla extract and rosewater.

Press the stewed rhubarb through a sieve into a bowl, pressing down with the back of a spoon to extract as much puree as possible. Lea
