Oxtails actually come from a cow.
Oxtail is skinned and usually sold cut in pieces.
I just have one question. Place Rabo in 8 quart pressure cooker and season with garlic power and onion powder. Add a small amount of blended seasoning and cook with the two bullion's until bullion's melt. Finally add the rest the blended seasoning, seal pressure cooker and cook for 30-50 minutes until the meat practically falls off the bone. As an extra tip use the sauce on a bed of white rice.
