There are 100 ways of cooking adobo and we all have our own recipe. I am sharing this recipe because others who have never cooked adobo just want to know how to prepare it the simple way.
In cooking adobo, the tip here is to cook the meat in low fire from start to finish (till the meat is tender) and sauce is reduced [Cook uncovered in the last 10 minutes]
The usual ratios are
1 kilo meat (chicken or pork): 1/2 cup native vinegar (reduce accordingly to acidity of vinegar).
1 kilo meat (chicken or pork): 1/2 cup vinegar: 1/4 cup water
Soy sauce can range from 2 tablespoon to 4 tablespoon per 1/2 cup vinegar
1 kilo meat: 1/2 cup vinegar or acid: 1/2 tablespoon coarse salt
2-4 tablespoon soy sauce: 5- 10 peppercorns: 1 laurel leaf
Heat the oil in a cooking pot.
Add the garlic. Saute until light brown . Then add onions. Not many people like to add onions but I like the sweetish taste of the onions in my adobo.
Put the pork belly in the pot. Stir and cook until it turns light brown.
Add the soy sauce and water to the pot. Let boil. Cover and cook in low heat for 30 minutes or reduce until the pork is tender. Add more water if the liquid starts to evaporate too much. The amount of sauce depends on how you want your adobo to look like. I prefer mine to have little sauce.
Pour-in the Marca Piña vinegar and comtinue to boil. Mix and cook for 10 more minutes. Do not stir vinegar till it has cooked. That is, when all the acid has evaporated. Your nose will tell.
Taste your adobo if it needs more salt. I find that the Marca Piña soy sauce has adequate salt already. But just add a pinch of salt as it helps balance the acidity.
