Overview

Prickly pear is the fruit of the Opuntia genus of cacti, native to the Americas. The fruit is oval, thick-skinned, and ranges in color from green to yellow, orange, red, and purple. Its flesh is juicy and sweet, with a texture similar to a melon or watermelon, and it contains numerous small, hard seeds.

Origin and history

Opuntia species are distributed throughout most of the Americas, from Canada to Patagonia, with the highest diversity in Mexico [1]. The genus contains about 200 species, though chollas are now separated into the genus Cylindropuntia, which some still consider a subgenus of Opuntia [1]. Prickly pears have been a food source in Mesoamerica for thousands of years. The nopal cactus pad (nopal) and the fruit (tuna) are both central to Mexican cuisine. The sour prickly pear variety known as xoconostle (Opuntia joconostle or O. matudae) is used to flavor churipo, a traditional Purépecha stew [2].

Varieties and aliases

  • Tuna: the Spanish name for the prickly pear fruit, used throughout Mexico and Central America.
  • Xoconostle: a sour variety of prickly pear (Opuntia joconostle or O. matudae), used in savory dishes [2].
  • Nopal: the cactus pad, not the fruit, but from the same genus.
  • Prickly pear: the common English name.

Culinary uses

The prickly pear fruit is eaten raw, peeled, and chilled. It is also juiced, made into jams, jellies, and syrups. In El Salvador, miel de tuna is a thick syrup made by reducing prickly pear fruit with sugar, a regional specialty in arid zones [3]. The fruit pairs well with citrus, chili, and mint. The seeds are edible but typically swallowed whole or strained out. The sour xoconostle is used in savory preparations, particularly in stews like churipo from Michoacán [2].

Cross-cuisine context

Prickly pear has no direct analogue in the other cuisines represented on the platform. Its closest parallel in texture and sweetness might be the dragon fruit (pitaya), which is also a cactus fruit, but dragon fruit is from the Hylocereus genus and is less sweet. The use of xoconostle as a souring agent in stews is functionally similar to the use of tomatillo or green tomato in Mexican cooking, or tamarind in Southeast Asian cuisines. The miel de tuna syrup from El Salvador is analogous to other fruit syrups like Korean mogwa-cheong (quince syrup) or Armenian doshab (grape syrup), though the base fruit is different.

Notes for cooks

  • The skin of the prickly pear is covered in tiny, hair-like spines called glochids. Handle with thick gloves or hold the fruit with tongs while peeling.
  • To peel, cut off both ends, make a slit lengthwise, and peel the skin away. The flesh can then be sliced or cubed.
  • Prickly pear juice can be used as a natural food coloring, turning dishes a vibrant magenta or red depending on the variety.
