One of my favorite kitchen products is flavored olive oils. Whether its rosemary, basil or oregano, they turn up the flavor of sauces, vinaigrettes, roasted veggies, and even skillet pizza. My go-to flavor is rosemary infused oil from Vom Fass, a local purveyor of flavored olive oils, vinegars and liqueurs. I haven't even begun to explore all of their offerings, but I can't wait to try out some of the more exotic flavors since they share some great ideas when I shop there.
The flavored oils don't leave a strong taste, but they do amp up the overall flavor. I suggest a trip to your local olive oil shop and indulge in a bottle to try with your favorite recipes. And, there's usually free taste samples!
