Filipino Pork Adobo is a traditional dish known for its tangy, savoury, and slightly sweet flavours. It's a simple yet delicious meal that combines vinegar, soy sauce, garlic, and spices to marinate and braise the pork, resulting in a tender and tasty dish. Here's how to make it:

1. 1. Marinate the Pork: Combine the diced pork with the vinegar, soy sauce, half of the minced garlic, and black peppercorns in a mixing bowl. Mix well, ensuring each piece of pork is coated. Allow to marinate for at least 30 minutes, or ideally, leave it in the refrigerator to marinate overnight for deeper flavour.
   2. Brown the Pork: Heat the oil in a large pot over medium-high heat. Remove the pork from the marinade (keep the marinade for later) and sear in batches until browned on all sides. Set aside browned pork.
   3. Sauté Aromatics: In the same pot, reduce heat to medium. Add the sliced onion and remaining garlic. Sauté until soft and fragrant.
   4. Braise the Pork: Return the browned pork to the pot. Add the reserved marinade, water, bay leaves, and brown sugar if using. Bring to a boil, then cover and simmer on low heat for about 1 to 1.5 hours, or until the pork is tender.
   5. Reduce the Sauce: Once the pork is tender, remove the lid, increase the heat slightly, and allow the sauce to reduce to your preferred consistency, stirring occasionally to prevent sticking.
   6. Final Seasoning: Taste and adjust seasoning with salt if needed. Remove bay leaves before serving.
   7. Serve: Serve hot alongside steamed rice, using the sauce to flavour the rice as well.

Filipino Pork Adobo varies from region to region and even from family to family. Some like it dryer, while others prefer a more saucy version. Adjustments to the soy sauce and vinegar ratios can also be made according to personal taste preferences.
