Boiling Corn On The Cob At High Altitude
Nothing says summer like a buttery ear of corn on the cob. Whether you are grilling it, roasting it or boiling it, corn is a staple of summer cookouts across America. However, if you live at high altitude, boiling corn on the cob can be a bit tricky. The lower boiling point of water at high altitude affects the cooking time and texture of your corn. But don't worry, with a few tips and tricks, you can still achieve perfect corn on the cob every time.
What is High Altitude?
High altitude is generally considered any elevation above 3,000 feet (914 meters) above sea level. At higher altitudes, the atmospheric pressure is lower which means that water boils at a lower temperature. In fact, the boiling point of water decreases by approximately 1°F (0.6°C) for every 500-foot (152-meter) increase in altitude. This means that water boils at around 203°F (95°C) at 5,000 feet (1524 meters) above sea level, compared to 212°F (100°C) at sea level.
How to Boil Corn on the Cob at High Altitude
Boiling corn on the cob at high altitude requires some adjustments to the traditional cooking method. Here are some tips:
Use a Large Pot
When cooking at high altitude, it's important to use a large pot with plenty of water to ensure that the corn cooks evenly. Use a pot that is at least 4 quarts and fill it with enough water to completely cover the corn.
Add Salt to the Water
Adding salt to the water will help raise the boiling point, making the water hotter and helping the corn cook more evenly. Use 1 tablespoon of salt for every 4 quarts of water.
Boil the Corn for Longer
At high altitude, the corn will take longer to cook than it does at sea level. Plan on boiling the corn for 12-15 minutes, or until it is tender.
Cover the Pot
Covering the pot while the corn cooks will help trap the heat and steam, which will help the corn cook more evenly. It will also help prevent the water from evaporating too quickly, which can lead to the corn becoming tough and chewy.
Don't Overcrowd the Pot
Overcrowding the pot can cause the corn to cook unevenly, so it's important to only cook as many ears of corn as will fit comfortably in the pot. If you have a lot of corn to cook, it's better to cook it in batches rather than trying to fit it all in one pot.
Conclusion
Boiling corn on the cob at high altitude may require a bit of extra effort, but it's well worth it for the delicious, buttery goodness that you will enjoy. By following these tips, you can achieve perfect corn on the cob every time, no matter how high you live.
