I've had this happen a handful of times: I've peeled and minced my garlic, heated up my oil,and then tossed it into the skillet/pot with my other aromatics, only to find a weird, unpleasantly waxy scent coming from the skillet. Tasting confirms what the nose fears: a bizarre, plastic/waxy flavor to the food. I'm pretty sure it's the garlic -- I thin it has happened before when I was cooking only that. And in case you're wondering, no, I didn't accidentally melt a spatula or have other mishaps. So, has anyone else experienced this? The flavor is strong enough that, to my palate anyway, it ruins the food. Any guesses as to the cause, and is there a way to identify it before the garlic is cooked and mingled with other ingredients?
