Inside a vanilla pod (Vanilla planifolia). Vanilla flavouring is derived from the seeds and pods of orchids of the genus Vanilla. The main component of vanilla essential oil is vanillin which gives it the characteristic aroma and flavour. Vanilla pods are used for flavouring foods and confections either entire, or cut open revealing the seeds as shown here. An alcoholic extract of the natural pods is also used.
