Achocha
Cyclanthera pedata
Achocha (Cyclanthera pedata), also known as caigua, stuffing cucumber, or slipper gourd, is a curious Andean climbing gourd that produces hollow, teardrop-shaped fruits perfect for stuffing. When young, the crisp, mild fruits can be eaten raw like cucumbers; as they mature, they develop a hollow cavity that invites creative fillings. This ancient Incan crop has been climbing Andean fences for millennia and is now gaining recognition worldwide as a productive, pest-resistant vegetable that doubles as an ornamental conversation piece.
• One of the "lost crops of the Incas," cultivated in the Andes since pre-Columbian times
• The hollow mature fruits are natural containers perfect for stuffing with meat, cheese, or vegetables
• Known as "caigua" in Peru and Bolivia, "achocha" in Ecuador, and "korea" in the Caribbean
• Extremely productive — a single plant can yield 50 to 100 fruits in a season
• Almost completely pest-resistant, making it ideal for organic gardens
• The species name "pedata" refers to the foot-shaped (pedate) leaf form
Taxonomy
• Domesticated in the Andean region at elevations of 1,000 to 2,500 meters
• Cultivated since pre-Columbian times by Incan and pre-Incan civilizations
• Remains an important home garden crop throughout Peru, Bolivia, Ecuador, and Colombia
• Introduced to the Caribbean, where it naturalized and became known as "korea"
• Brought to Europe as an ornamental curiosity in the 19th century
• Has gained a following among permaculture and exotic vegetable enthusiasts worldwide
• Also grown commercially in parts of Southeast Asia
• Still relatively unknown outside its native range compared to other Andean crops
Leaves:
• Large, palmate to pedate (foot-shaped), 10 to 20 cm across
• Deeply divided into 5 to 7 pointed lobes
• Bright green, slightly hairy, with serrated margins
• Resemble maple or cannabis leaves in general outline
Fruits:
• Elongated, teardrop to lantern-shaped, 5 to 15 cm long and 3 to 6 cm wide
• Green, sometimes with soft, faint spines or smooth skin
• Solid and crisp when young; develop a hollow cavity as they mature
• When fully ripe, fruits split open at the bottom to reveal black seeds
• Mild, cucumber-like flavor when young; becomes slightly sweeter at maturity
Flowers:
• Small, greenish-white to pale yellow
• Monoecious: separate male and female flowers on the same plant
• Female flowers are solitary; male flowers in small clusters
Vines:
• Slender, green, with curling tendrils for climbing
• Fast growth rate, covering supports rapidly in warm weather
• Thrives in warm temperatures between 18 and 30°C
• Can be grown as an annual in temperate climates with a sufficient growing season
• Prefers well-drained, fertile soils with pH 6.0 to 7.0
• Requires full sun for maximum productivity
• Needs sturdy support: trellises, fences, or teepees
• Consistent moisture is important for fruit development
• Exceptionally pest-resistant compared to other cucurbits
• Pollinated by bees and other insects
• Matures in 70 to 90 days from seed
• Very tolerant of poor soils once established
• Very low in calories, approximately 15 to 20 kcal per 100 g
• Good source of vitamin C, providing a refreshing boost
• Contains potassium, phosphorus, and small amounts of calcium
• Provides dietary fiber, especially in more mature fruits
• High water content (over 90%) makes them hydrating and refreshing
• Contains peptins and flavonoids with antioxidant properties
• Young fruits have a nutritional profile similar to cucumbers
• Traditionally used in Andean folk medicine for cholesterol management
• Sow seeds directly after danger of frost when soil has warmed to 18°C or above
• Soak seeds overnight to improve germination
• Plant 1 to 2 cm deep, 2 to 3 seeds per hill
• Space hills 60 to 90 cm apart along a sturdy trellis or fence
• Provide support at planting time — vines grow fast
• Germination in 7 to 14 days at warm temperatures
• Keep soil consistently moist but not waterlogged
• Begin harvesting young fruits 60 to 70 days after planting
• Harvest at any stage: small and solid for raw eating, larger and hollow for stuffing
• Pick regularly to encourage continuous production
Young fruits:
• Eaten raw in salads like cucumbers
• Pickled in vinegar with herbs and spices
• Added to stir-fries for their crisp, refreshing crunch
Mature fruits:
• The classic preparation is stuffed with spiced meat, cheese, or grains and baked
• Used in Peruvian "caigua rellena" (stuffed caigua)
• Can be sliced and added to soups and stews
• Used in stir-fries and curries
All stages:
• Used in salads, ceviches, and fresh salsas
• Can be preserved by pickling or canning
• Added to omelets and frittatas
Fun Fact
Achocha is one of the most productive vegetables in existence — a single healthy vine can produce over 100 fruits in a single season. Despite this incredible yield, it remains almost unknown outside South America, making it perhaps the most underappreciated member of the entire gourd family.
