Overview

Popcorn is a variety of corn (maize) whose kernels expand and puff when heated. The kernel has a hard, moisture-sealed hull and a dense starchy interior that allows pressure to build until it bursts. It is eaten as a snack, often salted or buttered, and is also used in confections and savory preparations across multiple cuisines.

Origin and history

Maize was domesticated in Mesoamerica roughly 9,000 years ago, and the earliest archaeological evidence of popped corn comes from Peru, where 6,700-year-old popped kernels were found at the Paredones and Huaca Prieta sites on the north coast. Indigenous peoples across the Americas popped corn by heating kernels on hot stones, in sand, or directly over fire. The Aztecs used popcorn in ceremonial headdresses and as a food. European colonists encountered popcorn in the 16th century; it became a popular snack in the United States by the 19th century, especially after the invention of the commercial popcorn machine in 1885.

Varieties and aliases

  • Popping corn (general term for any corn variety bred for popping)
  • Maíz palomero (Spanish, Mexico)
  • Maíz reventador (Spanish, Latin America)
  • Cancha serrana (Peru, for toasted chulpe corn, a related but distinct preparation)

Culinary uses

Popcorn is most commonly prepared by heating kernels in oil or hot air until they pop. It is eaten plain, salted, buttered, or flavored with spices, cheese, caramel, or chocolate. In Mexico, popcorn (palomitas) is sold by street vendors with lime, chili powder, and salt. In the United States, it is a standard movie theater snack. Popcorn is also used as a breakfast cereal with milk, as a coating for fried foods, and as a decorative element in some confections.

Cross-cuisine context

Popcorn has direct analogues in several cuisines represented on the platform. In Peru, cancha serrana is toasted chulpe corn that puffs irregularly into crunchy nuggets, served alongside ceviches and as a bar snack. In Guatemala and El Salvador, alboroto is a puffed grain confection made with popcorn (or puffed rice) bound with panela syrup, often colored bright pink or red, and sold at ferias patronales. In Taiwan, the term “popcorn chicken” refers to a dish of bite-sized fried chicken, not popped corn, but the name reflects the visual similarity to popcorn pieces. In the Andes, kiwicha (amaranth) is popped like miniature popcorn on a hot comal and eaten as a snack or ground into flour. In Inner Mongolia, chao mi is hulled millet dry-toasted in a wok until each grain pops slightly, producing a similar puffed effect.

Notes for cooks

  • Popcorn kernels should be stored in an airtight container to retain moisture; dry kernels will not pop well.
  • The ideal popping temperature is around 180°C (356°F). Oil with a high smoke point, such as coconut or canola, is recommended for stovetop popping.
  • A single kernel that fails to pop is called an “old maid.” These can be rehydrated by adding a teaspoon of water to the storage container and waiting a day.
