Butter or olive oil? Each of these offer a certain flavor profile.
Now you don't have to decide. Land O Lakes has put both flavors together in a new product, Butter with Olive Oil & Sea Salt. It comes in half-stick packages.
My recipe for caramelized onions calls for sauteing in half olive oil and half butter. I also have a great recipe for garlic bisque that uses both olive oil and butter. I'm looking forward to using this new butter to add some sizzle the next time I saute.
