Pass the butter -- er, margarine. Or is it the olive-oil spread?
In the so-called oil-and-fats category, it's getting tougher to tell which is which. Butter giant Land O'Lakes is adding olive oil to some of its sticks, marking what it says is a category first. Meanwhile, a canola-oil-blended butter spread continues to gain attention, and some versions also include, you guessed it, olive oil. At the same time, brands are adding dashes of sea salt, cinnamon and sugar to spice up what was once a pretty mundane dairy staple.
