Vanilla beans are the fruit of the vanilla orchid, a tropical plant native to Mexico. These long, slender pods are harvested when they are still green and undergo a curing process to develop their rich flavor and aroma. The beans contain tiny black seeds that are often used in cooking and baking. The flavor of vanilla beans is complex, with sweet and creamy notes that enhance a variety of dishes. They are commonly used in desserts like ice cream, custards, and cakes. Whole vanilla beans can be split open to scrape out the seeds or used whole to infuse flavor into liquids.
