Citrus Peels

Lemon, lime, grapefruit, orange… so much flavour lies trapped in those pretty skins. Scrape away the bitter white pith, cut into strips, and boil in sugar water for candied citrus peel. Or for fish-finishing citrus salt, leave peels to dry in a jar of sea salt, then grind. Ditto for white sugar. Add peels to cider vinegar for flavoured cooking vinegar, or to white vinegar for scented cleaning vinegar.
