Mint and lime flavored syrup is a bright, zesty infusion made by simmering sugar and water with fresh mint leaves and citrus zest until it develops a translucent, pale-green hue. Thanks to the crisp menthol of the mint and the sharp acidity of the lime, it delivers cool, herbaceous, and electrifying notes—often finished with a splash of fresh juice to keep the flavor punchy—making sparkling waters, mojitos, and iced gimlets taste sharper, more revitalizing, and more "spa-fresh" than regular simple syrup.
