Ulluco
What it is
The small, brightly colored tuber of Ullucus tuberosus, melloco (Ecuador) or papa lisa ("smooth potato"). Waxy, smooth-skinned, and gleaming in yellow, pink, red, and candy-striped patterns — among the most beautiful of the Andean tubers. Both the tuber and its leaves are eaten.
How it's made
Grown at high altitude as a hardy tuber. The defining trait is its high mucilage: when cut and cooked it can turn slightly slippery/gelatinous (like okra), and — unusually for a tuber — it keeps its crunch even after cooking and never goes mealy, because it is low in starch. Brilliant colors fade somewhat with cooking.
Flavor profile
Mild, earthy, and slightly nutty with a beet-like or grassy note, and a crisp, snappy, almost waxy texture that persists through cooking. Faintly mucilaginous. More about texture and color than bold flavor.
Culinary uses
A staple in Andean soups and stews, most famously Peruvian/Bolivian olluquito con charqui (julienned ulluco with dried llama or beef jerky). Boiled, added to sopas, or pickled. The leaves are eaten like spinach. Pairs with aji chilies, charqui/jerky, potato, and cheese.
Regional variations
Peru, Bolivia, Ecuador (where it is melloco), and Colombia. Each region has signature dishes; olluquito is iconic in Peru, while Ecuador favors melloco in salads and soups.
Cultural & historical context
A pre-Columbian Andean domesticate, second only to potato and oca among native tubers, vital to highland food security for its hardiness, storability, and color. It remains a culturally important everyday food and a symbol of Andean agrobiodiversity now championed by "lost crops" and food-sovereignty movements.
Substitution & sourcing — No close substitute for its color and persistent crunch; waxy potato is the nearest texture but goes soft. Rare outside the Andes — found fresh, canned, or frozen at Peruvian/Bolivian/Ecuadorian specialty markets. Canned ulluco is a practical option abroad for olluquito. Choose firm, vividly colored tubers.
