How many cups of corn is 2 cobs?

Quick Answer

Generally, 2 medium sized ears of corn equals around 2 cups of corn kernels. However, the exact amount can vary depending on the size and variety of the corn.

Calculating Cups of Corn Per Cob

To get a more accurate measurement, you’ll need to shuck the corn, remove the kernels, and measure them. Here are some general guidelines for estimating cups of corn per cob:

  • Small ear of corn: 3/4 – 1 cup of kernels
  • Medium ear of corn: 1 – 1 1/4 cups of kernels
  • Large ear of corn: 1 1/4 – 1 1/2 cups of kernels

So for 2 medium cobs, you would expect around 2 – 2 1/2 cups of fresh corn kernels.

Tips for Measuring Corn Kernels

  • Choose medium or standard sized ears of corn – very small or very large ears will alter the cup amounts.
  • Remove all silk strands and inner cores before measuring.
  • Pack the kernels loosely into the measuring cup – do not crush or compress them.
  • Measure to the top of the cup, not heaping.
  • Use standard US liquid measuring cups for accuracy.

Canned and Frozen Corn Measurements

The kernels from 2 fresh cobs is approximately equal to:

  • 1 1/2 – 2 cups frozen corn
  • 1 1/2 – 2 cups canned, drained corn

However, frozen and canned corn is usually more compacted than fresh cut kernels, so expect slightly different yields.

Whole Ear Cooking Times

If cooking the corn on the cob instead of cutting kernels, here are some estimated cooking times:

  • Grilling: 10-15 minutes
  • Boiling: 5-8 minutes
  • Roasting: 15-20 minutes at 400°F
  • Microwaving: 3-5 minutes

The timing can vary based on the size and freshness of the ears. Always check for doneness by piercing kernels with a fork or knife tip.

Equivalents for 2 Ears of Corn

In addition to cup measurements, here are some other handy equivalents for 2 medium cobs of corn:

  • 4 small corn tortillas worth of kernels
  • 1 1/2 cups corn for cornbread, muffins, etc.
  • 2-3 servings as a side dish
  • 1/2 recipe worth of corn salad or salsa

So two ears gives you plenty of corn for enjoying on the cob, adding to recipes, or freezing for later.

Typical Questions about Corn Measurements

Here are answers to some common questions about measuring corn in cups and cooking with corn ears:

How much corn in cups does an average ear yield?

An average sized ear of corn generally yields around 3/4 to 1 1/4 cups of corn kernels when cut from the cob. Very small ears may be closer to 1/2 cup and large ears up to 1 1/2 cups.

Can you freeze corn on the cob?

What is the difference between white and yellow corn?

White and yellow corn come from different cultivars but can mostly be used interchangeably. Yellow corn has a slightly richer flavor and more vitamin A, while white corn has a milder taste.

How long does corn last in the fridge?

Fresh corn will last 3-5 days when refrigerated and kept in its husk to retain moisture. Loose kernels or cut corn will only last 1-2 days. Cooked corn should be eaten within 3 days.

Can you reheat corn on the cob?

Yes, leftover grilled or boiled corn can be wrapped and reheated in the microwave or oven until warmed through. Steaming or quickly grilling again also revives corn. Just take care not to overcook.

Is corn good for you?

Yes, corn provides beneficial nutrients like antioxidants, B vitamins, fiber, and carotenoids. It also contains complex carbs and plant proteins. In moderation, corn can be part of a healthy diet.

Types of Corn

While most of us enjoy standard sweet yellow and white corn, there are actually many varieties grown:

Sweet Corn

Special varieties that “pop” when heated due to steam pressure inside the kernel. Smaller ears than other corn.

Sweet Corn vs Field Corn

Sweet corn is harvested young for eating fresh or cooking when kernels are soft, milky, and sweet. Field corn refers to varieties used for processing into food and industrial products, harvested when fully dried on the stalks.

Within these broader categories there are hundreds of specific corn cultivars with different colors, textures, and uses.
