Singkamas
Definition
Singkamas is the Filipino name for jicama (Pachyrhizus erosus), a climbing legume vine grown for its large, turnip-shaped tuberous root, whose crisp white flesh is sweet, juicy, and almost apple-like in texture. In the Philippines singkamas is overwhelmingly eaten raw — peeled and sliced, then sprinkled with salt or dipped in vinegar or bagoong — making it a signature street and summer snack. The plant thrives in the dry season, and its light-green lobed pods and vines are grown separately from the root crop in garden practice.

Also Known As
Jicama; Mexican turnip; yam bean; singkamas (Tagalog, from Nahuatl xicamatl via Spanish); sinkamas (older orthography).
Examples and Analogies
Singkamas plays the role in Philippine snacking that raw radish slices play elsewhere — a cool, crunchy, hydrating bite — but its sweetness puts it closer to a water-chestnut apple: the same refreshing snap found in fruit platters and salads.
Usage Scenarios
Vendors sell peeled singkamas spears with salt in paper cones at markets, bus stops, and beach outings, while households add cubes to fresh lumpia, fruit salads, and sisig-style textures, or simply serve chilled slices at meals. Food processors have also explored singkamas chips and sticks as a lighter snack alternative.
Strategies
Farmers plant singkamas toward the cool dry months for sweeter, denser roots, prune the vine’s flowers to channel growth into the tuber, and harvest before roots turn fibrous. Storing roots in cool, dry conditions keeps them crisp for weeks, and peeling just before eating preserves moisture.
Security and Safety Measures
Only the root of singkamas is eaten: the vines, pods, and mature seeds contain rotenone-related compounds and are toxic, so gardeners keep seed production plantings separate. Peeled roots sold in markets should be kept clean and chilled, as cut raw produce is prone to microbial contamination when displayed unrefrigerated.
Historical Context
Jicama was domesticated in Mesoamerica, and its Tagalog name — preserving its Nahuatl root xicamatl — records its journey through the Manila galleon trade, by which Mexican crops entered the Philippines from the sixteenth century onward. Colonial-period accounts already listed singkamas among market produce, and it has remained a dry-season fixture of Philippine markets ever since.
Challenges and Controversies
Singkamas is a quiet victim of supply-chain change: once abundant in dry-season street stalls, it now competes with packaged snacks, and some municipalities periodically flag cut-fruit vendors over hygiene concerns, putting raw singkamas sales under food-safety scrutiny. Agriculturally, its dual-purpose planting requirements — root crop versus seed crop — keep it a minor, specialized cultivation.
