Grapefruit has long been a staple ingredient on menus, but chefs and operators are beginning to call out varieties of these bitter citruses and targeting flavor profiles that lend a premium flair.

It's said the redder the flesh, the sweeter the flavor, but ruby red grapefruit still gives plenty of tartness and bitterness to a dish or beverage. Ruby red grapefruit's resurgence has been supported by chef-driven exploration across menus in salads and cocktails, and to brightening lighter proteins like fish and chicken.

The ruby red grapefruit is found on only 2% of menus in American restaurants but it is well within the mainstream of fast-casual restaurants, quick-service chains and others, and more than 80% of consumers know about it, according to marketing research firm Datassential.
