Corn
Sweet, milky, and faintly grassy when fresh; starchy and concentrated when dried or aged; smoky and nutty when grilled over high heat.
Lens analyzedCorn (sweetcorn) is a naturally sweet, starchy grain-vegetable eaten fresh off the cob, cut as kernels, or used as a pantry staple in its canned and frozen forms across virtually every cuisine.
Where it comes from
No crop shaped the Americas as profoundly as corn. Domesticated in Mexico thousands of years ago, it spread north and south through indigenous trade networks and became the dietary foundation of civilizations from the Aztec to the Iroquois. European colonizers brought it to Europe, Asia, and Africa, where it became a food security staple. Today corn is one of the world's most produced crops, and in North America it fills backyard barbecues, farmers markets, and pantry shelves in equal measure.
Varieties — Yellow sweet corn is the most common; white corn is sweeter and more tender; bicolor corn combines both. Silver Queen and Butter & Sugar are popular American varieties. Baby corn is harvested very early and eaten whole.
Corn is sacred in Mesoamerican cultures and remains central to Mexican cuisine in masa-based foods; Filipino street corn (mais con queso) is a popular snack; esquites (Mexican corn cups) and elotes (street corn) have become widely loved across North America.
In a modern kitchen — Fresh corn is sweetest the day it is picked — sugars convert to starch rapidly. Cook within 1–2 days of purchase. To cut kernels easily, stand the cob upright in a large bowl and slice downward — the bowl catches every kernel.
Buying it
Pull back the husk slightly to check the kernels — they should be plump, tightly packed, and milky when pressed. Silk should be pale gold to light brown. Husks should be bright green and moist, not dried out. Avoid cobs with gaps in the kernel rows.
Storing it
Keep corn in its husk in the fridge and use it within a few days — its sugars convert to starch quickly once picked, so it's best eaten sooner rather than later.
Keeps about 5 days in the fridge.
In season
Peak season is July–September, though it's available year-round.
Fresh local sweet corn is most common in midsummer to early fall, while packaged forms are available year-round.
Out of corn? Good swaps
- Frozen corn kernels — Excellent swap for fresh cut corn in cooked dishes — use 1:1 by volume, no prep needed
- Canned corn — Softer and less sweet; rinse and drain before using — 1:1 in soups, stews, and salsas
- Edamame — Different flavor but similar sweetness and pop; use 1:1 in salads and stir-fries — note edamame is soy, a major allergen corn doesn't carry
