The Artisanal Kitchen's digital pantry is hand-stocked by proprietor Anna Zoitas, a judge for the International Fancy Food Show who has examined more than 2,000 specialty foods and beverages. Two of the company's newest provisions are the cold-pressed Three Olives olive oil and authentic Aceto Balsamico Di Modena. Three Olives is an unfiltered, 100% extra-virgin fusion that blends a trio of distinct flavors. The arbequina olive pledges allegiance to Spain's Catalonia region and imparts a soft texture usually found only in cashmere sweaters. Palates detect a nuttier, spicier taste from the arbosana olive oil, whose high polyphenol level may reduce the risk of heart disease, and the Kalamatan koroneiki olive oil bears a fruitier aroma. Three Olives' mellow taste renders it ideal for cooking, dipping, and making dressings, although its low acidity (less than 0.5%) renders it useless as battery fuel. A bottle of Aceto Balsamico Di Modena, a silky, sweet, and robust vinegar from Italy enriched by lambrusco and trebbiano grapes, plays a beautiful countermelody to the olive oil's symphony.
