I collect mint leaves and chop them as finely as possible. Then place them into an ice cube tray and pack down, cover with water as if making everyday ice cubes. Place in the freezer to harden.
Use throughout Winter by popping out one or two mint cubes and make mint sauce your usual way.
For me I like to put two ice cubes into a mug, cover with hot water and add sugar and vinegar to taste.
