This aromatic fruit is available year round from Florida, California, and New Zealand. Store it at room temperature until slightly dimpled, then store it in the shell in an airtight freezer bag in the refrigerator for up to a week or in the freezer for up to a year. One passion fruit equals 1½ tablespoons of puree. Although no one having indulged in the fruit would question the appropriateness of the name, the term “passion fruit” actually came from Catholic missionaries in Brazil who, upon seeing passion fruit vines in flower around Easter, were reminded of the passion of Christ and the crucifixion.
