Pack a glass jar full of young spring beech leaves, then fill up with gin.
Cover and leave for at least 3 weeks.
Three weeks later, strain off the gin (which has changed to a dirty colour).
To every 570ml (1 pint) of gin allow 250g (9oz) caster sugar which has been dissolved in 275ml ( pint) of boiling water.
Mix well and add a tablespoon of brandy if you wish and cork.
