Chicken Adobo
Philippines (pre-colonial preservation technique; Tagalog region as the canonical version)
Chicken adobo is the Philippines' most emblematic dish — chicken pieces braised in a mixture of cane vinegar, soy sauce, garlic, black peppercorns, and bay leaves until the sauce reduces to a sticky, deeply savoury glaze. The word 'adobo' refers to the preservation technique (acid and salt) rather than a specific spice blend, which is why Filipino adobo bears no relation to Latin American adobo. The technique is one of the world's most effective natural preservation methods: the combined effect of vinegar's acidity, soy sauce's salinity, and the reduction of the cooking liquid to a high-concentration syrup creates an environment hostile to bacterial growth. Adobo is notably better the next day — the acid tenderises further and the flavours integrate. Regional variations are legion: Cavite adobo uses coconut milk; Batangas adobo uses turmeric.
