Adobo refers to a method of marinating and stewing for any cut of meat or fish in a briny mixture of vinegar, soy sauce, and spices. Filipino adobo should not be confused with the spicy Spanish adobo sauce. Although they both share the Spanish name, they are vastly different in flavor and ingredients. Like many cultures based in warm climates, Filipino natives developed various methods of preserving food. Adobo utilizes the acid in the vinegar and the high salt content of soy sauce to produce an undesirable environment for bacteria. Its delicious flavor and preserving qualities served to increase adobo's popularity. The adobo was traditionally cooked in clay pots but today is made in more common metal pots or woks.

When the Spanish invaded and settled in the Philippines during the 16th century, they witnessed this traditional Filipino cooking method and called it adobo, which is the Spanish word for marinade.
