New evidence indicates that ~2.9 million years ago, early human ancestors used some of the oldest stone tools ever found to butcher hippos and pound plant material, along the shores of Africa’s Lake Victoria in Kenya

The taste is mild, less than lamb and more than beef, slightly more marbled than usual venison

The meat of a hippo has about three times more unsaturated fats than beef, which means that it can be cooked without any added oil or butter and still taste juicy

The taste of the flesh is often described as being similar to beef, with a slightly sweet flavor and tough texture

if cooked with spices such as cumin seeds then its flavor will resemble venison

While cooking without seasoning gives off more pork flavors

Their meat encompasses everything from sweet to savory, backed with a firm texture. The closest they taste like is beef. But hippos are more flavorful and somewhat gamey
