Floral perfumed notes from lychee pair perfectly with the delicate citrus aromas of yuzu. Excellent in soda, a great mixer for gin-based drinks (with alcoholic or non-alcoholic gin), and lovely splashed into iced tea - try a green tea, jasmine, or oolong.
You can also use this cordial to make your own popsicles or flavoured ice cubes. Go on, make Martha Stewart proud. :)
