- Wash the oxtails, pat them dry, and put them in the slow cooker.
- Combine the spices, soy sauce, vinegar, honey, and oil in a bowl and mix thoroughly. Pour the mixture over the oxtails.
- Cover the crockpot, program to LOW, and cook for eight hours. You want the meat tender and falling off the bone.
- Once the time is reached, drain the sauce into a saucepan and set the crockpot to WARM.
- Cook the sauce over medium heat and whisk in a blend of cornstarch and water. Stir and whisk until the sauce is thickened into a glaze- about three to five minutes.
- Serve the oxtails warm, with the thick sauce poured over them.
