For one drink, fill a large glass with ice, add 25ml of gin - I find that Bombay Sapphire works best in this recipe - and 25ml of La Nique rose petal liqueur (available from Vintage House and Gerry's - both on Old Compton Street, W1). Stir gently and strain into a chilled Martini glass, using a rose petal as a garnish. Edible flowers are available afrom most high street florists.
