Barbecue corn on the cob is a classic summer treat, and grilling it in foil ensures that it stays moist and tender. But the question of how long to cook it can be tricky. There's no one-size-fits-all answer, as the ideal cooking time depends on the size and type of corn, your barbecue's heat, and how tender you prefer your corn. This article will guide you through the process, providing a comprehensive understanding of the factors influencing cooking time and offering practical tips for achieving perfectly grilled corn.
Understanding the Basics
The key to perfectly cooked corn on the cob is to understand the factors that influence cooking time.
Corn Size and Type
The size of the corn ears plays a significant role in determining how long they need to cook. Larger ears will naturally take longer than smaller ones.
Here's a general guide:
- Small ears (less than 6 inches): 15-20 minutes
- Medium ears (6-8 inches): 20-25 minutes
- Large ears (over 8 inches): 25-30 minutes
The type of corn also affects the cooking time. Sweet corn, with its higher sugar content, cooks faster than field corn.
Barbecue Heat
The temperature of your barbecue is another crucial factor. Higher heat will reduce cooking time, while lower heat will increase it.
- High heat (400-450°F): 15-20 minutes
- Medium heat (350-400°F): 20-25 minutes
- Low heat (300-350°F): 25-30 minutes
Desired Tenderness
Finally, your personal preference for tenderness will also affect cooking time. If you prefer your corn a bit crunchy, you can cook it for a shorter time. For softer corn, cook it longer.
How Long to Barbecue Corn in Foil
Now, let's get to the heart of the matter: how long to barbecue corn in foil. Here's a comprehensive guide to help you get it right:
-
Prepare the corn: Remove husks and silks from the corn ears.
-
Wrap the corn: Place each ear in a piece of aluminum foil, large enough to wrap it completely. Add butter, herbs, and seasonings to the foil.
-
Preheat your barbecue: Preheat the barbecue to medium heat (350-400°F).
-
Place the corn on the grill: Place the wrapped corn ears directly on the grill grate.
-
Cook the corn: Here's where the general guideline comes in:
- Small ears: 15-20 minutes
- Medium ears: 20-25 minutes
- Large ears: 25-30 minutes
-
Check for doneness: After the estimated cooking time, remove one corn ear from the grill and carefully unwrap it. The corn should be tender and the kernels should be plump.
Tips and Tricks
Here are some tips for grilling corn in foil to perfection:
- Don't overcook it: Overcooked corn will be mushy. Keep an eye on the cooking time and check for doneness frequently.
- Use a meat thermometer: For more precise results, use a meat thermometer to check the internal temperature of the corn. It should reach 180°F for optimal tenderness.
- Experiment with flavors: Get creative with your seasonings. Try adding garlic powder, onion powder, chili powder, or paprika. You can also use herbs like parsley, oregano, or basil.
- Add some sweetness: Sweeten the corn with a tablespoon of sugar or honey.
- Try adding cheese: Sprinkle grated cheese over the corn before wrapping it in foil. This will melt into a delicious sauce.
Conclusion
Barbecue corn in foil is a simple yet satisfying dish. The ideal cooking time depends on the size and type of corn, your barbecue's heat, and your desired level of tenderness. By following these tips and adjusting the cooking time as needed, you can grill perfectly delicious corn on the cob every time. Enjoy!
