The key ingredient in this recipe–outside of luscious, red-ripe strawberries–is Cointreau.

Cointreau is a well-known liqueur from western France, where it was first made more than a century and a half ago in the city of Angers. Colorless and with a strong, pleasing aroma, it has an exotic flavor that is a marriage of sweet orange peels from Spain and bitter orange peels from the Caribbean island of Curaçao. Although similar to triple sec, Cointreau is drier.
