Use a sublime olive oil and you can transform the most ordinary fare into something special. Olive oils can be described as buttery, silky, light, fruity, grassy, rustic, and peppery. We’ve gathered our favorites here from the traditional Mediterranean countries, California, and even South Africa. Like wine, the flavor varies with the region, the climate, the cultivar, and the time of harvest. We know that you’ll find a favorite among these.
