Adobo

Adobo or adobar is the immersion of food in a stock (or sauce) composed variously of paprika, oregano, salt, garlic, and vinegar to preserve and enhance its flavor. The Portuguese variant is known as carne de vinha d'alhos. The practice, native to Iberia (Spanish cuisine and Portuguese cuisine), was widely adopted in Latin America, as well as Spanish and Portuguese colonies in Africa and Asia. In the Philippines, the name adobo was given by colonial-era Spaniards on the islands to a different indigenous cooking method that also uses vinegar. Although similar, this developed independently of Spanish influence. In the years following the arrival of Europeans to the Americas, meat and fish began to be preserved by new methods. Low temperatures facilitate food preservation, but in higher temperatures, other techniques, such as adobo, became necessary. Animals were usually slaughtered in the coldest months of winter, but surplus meat had to be preserved in the warmer months. This was facilitated through the use of adobos (marinades) along with paprika (a substance that may have antimicrobial properties due to the capsaicin content). Paprika gives a reddish color to adobos, and the capsaicins in paprika dissolve in fats, allowing its penetration beyond the tissue surface.
