Grilled Corn on the Cob with Smoky Onion & Tomato Relish
Ingredients
Method
- Remove corn husks: Remove the corn husks if desired. I left mine on for appearance.
- Heat the barbecue: Melt butter (or oil) on a pre-heated barbecue on medium heat.
- Grill the corn: Place corn cobs onto the barbecue, cooking on slow heat, turning occasionally until nicely grilled and tender (approximately 10-15 minutes). It’s best to constantly turn the corn to ensure even cooking.
- Grill the onions: Whilst corn is cooking, add sliced onion to the barbecue. Sauté until browned, grilled and smokey. Set aside.
- Assemble the corn: Once the corn is tender and grilled, remove from the barbecue along with the cooked onions. Top with sautéed onions, tomato relish (or salsa), and chopped parsley. Enjoy!
