What is Tempeh?
Tempeh, a traditional Indonesian food made from fermented soybeans, has gained popularity worldwide as a nutritious plant-based protein source. This unique food product is not only favored by vegetarians and vegans but also appeals to health-conscious eaters seeking to incorporate more whole foods into their diets.
The History of Tempeh
Tempeh has its roots in Indonesia, where it is believed to have been created over 1,000 years ago. Initially a local staple, tempeh has transformed into an essential component of global cuisine.
