I don't venture into expensive shops very often. However in both Sacramento and San Diego, I found myself being walked into Olive Oil boutiques by the husband; forced to taste quite a few of them. As weird as drinking olive oil and balsamic vinegar still is to me, we did find a few diamonds.
Mix up your regular meals by adding flavored olive oils --> jalapeno olive oil adds a zing to a quesadilla or grilled cheese sandwich. You can also use it in stir fry. Be careful not to add too much -- it is a very thin line.
Create a salad dressing with raspberry balsamic vinegar, or use a lemon balsamic in your fajitas.
These little things give old dishes a fresh spin.
