A recipe that works even for orange-flavoured anything haters like me! (Remember the ad a few years ago? There was a sexy Frenchman who seduced the woman at the dinner table with his eyes and a glass of orange liqueur. This recipe is Frenchman-free, but infinitely cheaper!)
Cut the peel of 10 medium oranges into eight sections and place on a baking sheet. Heat in the oven at the lowest setting for several hours until hard and brittle.
Place the peel in a wide-necked glass jar and pour in about 75cl gin to cover. If necessary, remove some of the peel or add more gin to ensure that the gin covers the peel. Seal the jar and leave in a dark place for six weeks, shaking the jar several times a week.
Put the sugar and 1/2pt water in a pan and heat gently, stirring, until the sugar has dissolved, then bring to the boil and boil for 3 minutes. Remove from the heat and leave until cold.
Strain the peel and gin through a nylon sieve, pressing the peel lightly with the back of a wooden spoon. Add the syrup to the orange gin, then strain through muslin.
Pour into small bottles and seal. Store in a cool place for two months before serving as a liqueur.
