In a new video series on our It’s Complicated YouTube channel, we’re on a mission to untangle confusing everyday topics by speaking directly with experts

Whether you’re frying an egg or dressing a salad, cooking oils are a staple in most kitchens, but figuring out which one to use can feel strangely complicated.

Coconut oil, butter, avocado oil – everyone seems to have a different theory.

In a new video series on our It’s Complicated YouTube channel, we’re on a mission to untangle confusing everyday topics by speaking directly with experts and asking the questions people actually have. In an upcoming episode, we’re turning our attention to cooking oils.
