tbs. rosemary infused olive oil or extra-virgin olive oil plus 1/4 tsp. dried rosemary

Extra-virgin olive oil is a cold-pressed oil extracted from the fruit of the olive tree (Olea europaea), a species native to the Mediterranean region. It is the least processed form of olive oil, obtained through mechanical means without heat or chemical solvents, and must meet strict chemical and sensory standards to qualify for the "extra-virgin" designation. The oil exhibits a complex flavor profile ranging from grassy, peppery, and herbaceous to fruity and buttery, depending on harvest time, cultivar, and terroir. Early-harvest oils tend toward brighter, more vegetal notes, while late-harvest oils develop more robust, fruity characteristics.

Rosemary-infused olive oil is prepared by steeping fresh or dried rosemary (Rosmarinus officinalis) sprigs in extra-virgin olive oil, allowing the herb's essential oils and flavor compounds to permeate the oil over days or weeks. This infusion imparts rosemary's distinctive piney, slightly camphoraceous, and herbaceous character directly into the oil, creating a ready-to-use flavored condiment that intensifies the pairing of these two Mediterranean staples.

Extra-virgin olive oil serves as both a finishing oil and cooking medium in Mediterranean, Italian, Spanish, and Greek cuisines. It is drizzled over soups, salads, bruschetta, and finished dishes to add depth and complexity. Rosemary-infused olive oil specifically enhances roasted vegetables, grilled meats, focaccia, and bread dipping preparations. The herb-oil combination is particularly effective with lamb, potatoes, and hearty root vegetables. While extra-virgin olive oil's low smoke point (approximately 160–190°C / 320–375°F) makes it unsuitable for high-heat cooking, it excels as a finishing agent and in cold preparations, vinaigrettes, and dipping oils.
