In Turkish culture, this floral, citrusy, sweet cordial is believed to have protective properties: If someone trips on a flat path, it's poured on the spot to ward off the evil eye. Magical properties aside, this chilled, sunshine-yellow drink gets its hue from saffron threads; grinding them with sugar helps them dissolve easily. If saving overnight, discard the lemon slices, as they can turn the cordial slightly bitter. During Ottoman times, şerbeti made with saffron was commonplace at communal bathhouses known as hammam; nod to its roots by making this cordial part of a moment of self-care, or enjoy it anytime you need a refreshing drink.
