Cooking in foil is a very useful barbecue technique and is a good way to use the coals while they are burning down. I first discovered this method of cooking many decades ago and there is hardly a barbecue goes past without something being cooked this way. Lots of things can be cooked wrapped in foil such as potatoes, salmon and as in this case onions. You can even try tomatoes with olive oil, balsamic vinegar and salt.
Be careful not to burn yourself with the coals, use long handled tongs and turn the food regularly to make sure it doesn’t burn on one side. Use butter, olive oil or vegetable oil to coat the food to make sure it doesn’t stick to the foil. Also be aware that if the oil leaks into the coals it can cause a flare up so wrap the food well, sometimes two layers of foil are useful. Some foods will benefit from being wrapped loosely to allow them to steam.

Baked Onions
Ingredients
- 4 Onions
- Butter
- Curry powder
- Salt and pepper to taste
Instructions
- Simply peel the skin from the onions and cut off the roots. Use an apple corer to take out the middle of the onion. Mix the curry powder with butter and force into the middle of the onion with a spoon. Spread some butter over the outside of the onion and season with salt and pepper. Wrap in foil and place in the coals of the barbecue. Turn occasionally with long handle prongs to prevent burning and cook for around 20 – 30 minutes.
