Introduction to Artichoke Hearts in Oil
Artichoke hearts are the edible core of the artichoke flower, typically harvested from the globe artichoke plant. They are a rich source of fiber, vitamins, and minerals, making them a popular choice among health-conscious consumers. Artichoke hearts in oil are produced by packing the hearts in airtight containers filled with oil, usually olive or sunflower oil, to preserve them and enhance their flavor.
