Is fennel the same as star anise?

　　Fennel is generally not star anise. A detailed analysis is as follows:

　　Fennel and star anise are distinct from each other in botanical classification, morphological characteristics, and usage. Fennel belongs to the genus Foeniculum in the family Apiaceae (Umbelliferae). Both the fennel seeds and the tender stems and leaves are edible. Fennel seeds are small cylindrical in shape, mostly grayish-green or pale yellow in color, with an aromatic smell and a sweet taste. In contrast, star anise is the fruit of the plant species belonging to the genus Illicium in the family Magnoliaceae. It typically has eight carpels arranged in a star shape, is reddish-brown in color, and has a strong, distinctive aromatic and spicy fragrance. In culinary applications, fennel seeds are commonly used as a spice in cooking meat and seafood dishes, while the tender stems and leaves can be consumed as vegetables. Star anise, on the other hand, is primarily used as a spice to enhance flavor in braised and marinated foods.

　　To avoid confusion or negatively affecting the outcome of cooking, it is recommended to carefully check the recipe requirements and prioritize the use of the specified spices. When purchasing, pay attention to packaging labels or consult professionals to ensure correct identification and usage.
