Olluco

Olluco (Ullucus tuberosus) is one of the oldest cultivated tubers of the Andes, grown alongside potatoes and oca for thousands of years in Peru, Bolivia, Ecuador, and Colombia. It belongs to the Basellaceae family—related to malabar spinach—not the beet family as its sometimes confused cousin, ulluco. The tuber ranges from egg-sized to small potato-sized, with thin, edible skin in shades of yellow, orange, red, purple, and striped patterns. What sets olluco apart from nearly every other tuber is its remarkable ability to retain a firm, snappy bite even after cooking—a quality so distinctive it defines how the ingredient should be handled in the kitchen. The flesh is mildly sweet and earthy, less starchy than potato, with a dense crunch that holds up beautifully in soups, stews, and salads. In Peruvian cuisine, olluco is the defining element of olluquito con charqui, where its texture provides essential contrast to the chewy dried beef. While still a specialty outside South America, olluco appears with increasing frequency in Latin American markets and specialty produce shops, rewarding cooks who seek it out with an ingredient that behaves unlike anything else in the potato drawer.
