For years I used canola oil, vegetable oil, peanut oil and olive oil.  Then I ventured into the better extra virgin olive oils and realized I can tell the difference.  But what about all those other oils on the shelf?  I think grapeseed oil is worth discovering.  It’s lighter than olive oil, a bit nutty and easy to fry with or it makes a great salad dressing.  I use it as I do olive oil with a bit of vinegar or lemon, some Dijon and salt & pepper, a great light dressing.  It has become a pantry staple.
