Place Ox Tail or Beef Meat in a crock pot add the water
Slow cooked on high for 2 hours on high or overnight on low for 4 hours. When using Beef, lower the cooking time . ( I recommend setting a timer in your slow cooker, as we don't want the meat to be too soft.)
When the meat are done and ready, heat the cooking oil in a separate cooking pan and saute' garlic and onion. Around 2 minutes.
Add in the broth from the cook meat , the eggplant,banan heart and string beans (if using ),and let it simmer to blend the flavors, and cook until the eggplants are soft.
Add in 1/2 to 2/3 cup of peanut butter.YOUR AIM SHOULD MAKE THE SAUCE CREAMY AND WITH A GENTLE TASTE OF PEANUT BUTTER (NOT OVERWHELMING), SO ADD THE PEANUT BUTTER VERY SLOWLY.
Keep on stirring so as not to burn the peanut butter at the bottom of the cooking pan.
Season with the fish sauce.
Add the Oxtail meat and the bok choy.
Serve with sauteed Shrimp. Enjoy this Filipino cuisine!
