Start by gathering all your ingredients. Cut 1 kg goat meat into 2-inch cubes, crush 2 thumbs of ginger and 8 cloves of garlic, and quarter 2 medium onions.
Fill a large pot with 4 cups of water. Add your crushed ginger, quartered onions, and 1 tablespoon of salt. Turn heat to medium-high (180°C/350°F) and bring to a boil.
Once boiling, add your goat meat to the pot. Lower the heat to a gentle simmer (140°C/285°F). Cover and cook for about 45-60 minutes, occasionally skimming off any scum that rises to the top. The meat should be tender enough that a fork easily goes through it.
When the meat is tender, drain it in a strainer and set aside. You can discard the cooking liquid and aromatics.
Get a deep pan and heat 3 tablespoons of cooking oil over medium heat (160°C/320°F). Add your crushed garlic and cook until it turns light golden brown.
Add your pre-cooked goat meat to the pan. Stir and cook until the pieces are lightly browned on all sides.
Pour in ¼ cup soy sauce and 1 cup water. Add 1 tablespoon whole peppercorns and 4 dried bay leaves. Let this simmer for 10 minutes.
Add ¼ cup vinegar. Important: do not stir right away. Let it boil for 2 minutes untouched.
Lower the heat and simmer for 15-20 minutes until the sauce thickens to your liking. If you want it spicy, add 5 dried chilies in the last 5 minutes.
Your Adobong Kambing is ready when the sauce has reduced and coats the meat nicely. Serve hot with steamed rice.
Remember: You can always adjust the seasoning to taste before serving. If the sauce is too thin, simply simmer longer. If it's too thick, add a splash of water.
