Sardines and anchovies are different types of fish. While sardines have white flesh and can be up to 8 inches in length, anchovies have dark, reddish-gray flesh and are typically less than 6 inches long. Additionally, their flavors are different. Sardines are known for being "fishy" tasting and anchovies have a strong umami flavor, which results from the curing process. Anchovies are commonly added to savory dishes, like pasta and pizza. On the other hand, sardines are a great addition to recipes that require a less intense flavor. Both of them can be grilled, fried, filleted, or prepared using a variety of other fish cooking methods.
