Fruit Intelligence: Searching for Passion Fruit in Peru

Passion fruit is an ingredient that transcends seasonality – it provides tropical warmth in the winter months and brings a refreshing brilliance to the heat of summer. While its name may evoke romantic notions – and many of us therefore include passion fruit in our Valentine’s Day sweets – the moniker was inspired by religious symbolism assigned to the complex structure of the plant’s flower.

Passiflora edulis is a vigorous vine species of passionflower native to South America. It is cultivated commercially in tropical and subtropical areas for its sweet and tart fruit. The fruit is a pepo, a type of berry, round to oval, and either yellow or dark purple at maturity, offering a soft, juicy pulp filled with numerous edible seeds.

Of the estimated 500 species of Passiflora, of which a few dozen produce fruit, only P. edulis has the exclusive designation of passion fruit. Within the species there are numerous cultivars of two distinct forms. The bright yellow Flavicarpa variety can grow to the size of a small grapefruit, with a smooth, glossy rind. The dark purple edulis variety is much smaller, with less complexity in terms of sugar and acid balance.

Perú is one of the leading exporters of the yellow passion fruit and, surprisingly perhaps, much of the country’s production originates in the coastal desert zone, though the arid landscape is punctuated by fertile green valleys. Much of raw material in Les vergers Boiron’s passion fruit puree is sourced from this region of Perú.

A highlight among my travels in recent months was the opportunity to visit with some of Boiron’s producer partners in Perú last November. I’ve always found joy in connecting to the source of the ingredients we work with every day, and moments in the farms often leave indelible memories long after. One also gains respect and appreciation of the work necessary to produce world-class fruit. I don’t think I’ll ever again taste passion fruit without being transported back to the verdant fields near the small town of Casma, nestled along Perú’s northern coast.

Along the eight-hour drive north out of Lima, this extreme environment may on the surface appear inhospitable to any life all, let alone commercial agriculture. But ever larger patches of lush green begin to fill in the landscape. This modern farmland was first cultivated by ancient complex farming cultures, who mastered irrigation systems from snowmelt originating high in the Andes.

The area produces a range of crops, from corn and sugarcane to asparagus and avocado. Fruits that thrive in these green valleys include mango and pithaya (dragon fruit), and, of course, passion fruit. Ruben Barrera, one of the producers whose passion fruit crop ends up in Boiron’s blend, began planting yellow Flavicarpa passion fruit just over two years ago. Each vine is grown from seed in his own nursery, then transplanted in the field and trained on trellises. Flowers begin to bloom in as little as six months.

These large purple flowers open each day, timed to the emergence of the warm afternoon sun. Though bees and other insect pollinators visit the flowers, hand-pollination is a more reliable method for producing high-quality fruit (I learned how to pollinate a few flowers myself!). Large, mature fruits then develop quickly – ready for collection within two to three months. In addition to a change in color from green to yellow, a common determination of ripeness during the harvest period is to simply allow the fruits to fall naturally to the ground or into nets stretched along the vines. There are generally two fruiting seasons for passion fruit in Perú, in the Fall and the Spring. Along with its trademark acidity, high-quality specimens also provide a natural sugar content, registering as high as 14° Brix.

In addition to careful blending of fruit from different regions to achieve an optimal, consistent flavor profile, the initial extraction process is also incredibly important. The passion fruit pulp is gently liberated from the husk and seeds; by preventing the seeds from being crushed during refining, we also prevent bitter notes and muted color in the finished puree.

Once an obscure, exotic flavor, passion fruit has undoubtedly risen to the ranks of mainstream popularity. Its signature sweet-sour complexity shines on its own in a range of dessert and beverage applications. Passion fruit also blends well with a wide array of other fruits: tropical fruits, of course, as well as orchard and red fruits. Its intensity matches the bold flavors of chocolate, ginger and chili peppers; its sophisticated aromatic notes also allow passion fruit to harmonize with more subtle herbal and floral ingredients.

My visit to Perú certainly deepened my understanding of the expertise and efforts our farmer partners put into growing exceptional fruit. But travel can also inspire us in unexpected ways. Immersion in Perúvian food and culture provided a trigger that led me to conceptualize how I might creatively combine traditional ingredients in ways I hadn’t previously considered.

The combination of flavors that set things off were derived from a savory dish – the classic Peruvian ceviche. It occurred to me that the key elements of that fresh seafood mélange (sweetness, acidity, heat, starch) could easily be lifted from the savory realm and reworked into the context of dessert. The result was a petit gâteau conceived from the idea that ‘what grows together goes together’ – featuring a passion fruit and sweet potato fluid gel, a pâte sucrée and frangipane accented with cashew, and a coconut mousse glazed with an additional dose of passion fruit.
