Tastes like chicken

"Tastes like chicken" is a declaration used when trying to describe the flavour of an unusual food. The expression has been used so often in popular culture that it has become a cliché. As a result, the phrase is also sometimes used to provide incongruous humor, by being used to describe foods or situations where it has no real relevance.

As an explanation of why unusual meats would taste more like chicken than common alternatives such as beef or pork, different possibilities have been offered. One idea is that chicken has a bland taste because fat contributes more flavour than muscle (especially in the case of a lean cut such as a skinless chicken breast), making it a generic choice for comparison. Also, chicken reportedly has lower levels of glutamates that contribute to the "savory" aspect of taste known as umami; processing or tenderizing other meats would also lower glutamate levels and make them taste more like chicken.

Another suggestion, made by Joe Staton of the Museum of Comparative Zoology, is that meat flavors are fixed based on the "evolutionary origin" of the animal. Specifically, he noted that tetrapods largely taste like chicken, whereas other animals usually do not. Accordingly, birds (the most numerous form of meat by type) would (in most cases) naturally taste more like chicken than mammals. Furthermore, because dinosaurs are ancestral to birds, their meat would hypothetically have also tasted like chicken. However, the meat of other fowl often tastes nothing like chicken; for example, pheasant meat is described as a "unique" flavor and ostrich meat is thought to taste very similar to beef.

Seafood, however, would logically have a more distinctive flavor. Also, although mammals are tetrapods, very few mammals taste like chicken, which implies that there had been a mutation that changed their flavour on that branch of the evolutionary tree.
