I love oven roasted garlic. I even have a dedicated terracotta thingy I use to do the roasting in my conventional oven. The new improved recipe off the Interwebs said to wrap the garlic cloves in damp paper towels and microwave on high for 2 minutes. I put the wrapped cloves in the microwave, set the timer and went outside. I came back in about 15 minutes later and the cloves of garlic had caught afire inside the microwave and it was still going. Kitchen full of smoke and the odor of charred garlic and paper through the whole house. I had set the timer for 20 minutes instead of 2. Ruined the microwave.
