Bumbu is the Indonesian word for spices mixture or seasoning, and it commonly appears in the names of certain spice mixtures, sauces and seasoning pastes. It is commonly found in Indonesian cuisine, which includes its regional variants such as Balinese, Javanese, Sundanese, Padang, Batak and Manado cuisines. It is spread over various meats, poultries, seafoods and vegetables; used in stews, soups, barbecue, sotos, gulais, and also as a common addition to Indonesian-style instant noodles.
The spice mixture are commonly made by slicing, chopping, grounding, beating, bruising or sometimes burning the spices, using traditional cooking tools such as stone pestle and mortar, to modern blender or food processor. The bumbu mixture usually were stir fried in hot cooking oil first to release its aroma, prior to adding main ingredient (meats, poultry, or fishes).
The main function of bumbu is actually the same as common spices; as flavouring agent, to add, enrichen and/or to enhance taste and aroma.

Some of spices are known to inhibit the growth of microbes. That is why if cooked properly, dry rendang can last for as long as four weeks and still safe to be consumed.
