Tempoyak

Tempoyak , asam durian or pekasam is a Malay condiment made from fermented durian. It is usually consumed by the ethnic Malays in Maritime Southeast Asia, notably in Indonesia and Malaysia. Tempoyak is made by crushing durian flesh and mixing it with some salt and kept in room temperature from three to seven days for fermentation. Tempoyaks are usually made during the durian season, when the abundance of durian and excess production are made into fermented tempoyak. Tempoyak is not normally consumed solely, it is usually eaten as condiment or as an ingredient for cooking; such as cooked with coconut milk curry as gulai tempoyak ikan patin (pangasius fish tempoyak curry), or mixed with spicy chili pepper as sambal tempoyak.
