To the poster on here who is having a hardtime making Oxtails taste like the places you eat,it's simple doing all of that extra stuff is how you ruin Oxtails.
-Cut off the large peices of fat that's visible,wash,inspect the meat whatever
-Boil fill the pot not to the top depending on how many Oxtails you have you want the water to cover the top of them in depth for 1-2 hours in a pot with no lid or cover and make sure water is hot but not boiling over or steaming.
-After that pour off any extra water but save about a cup full of water and pour into an aluminum pan,hot
-Prepare a aluminum pan and foil by cover the pan with the oxtails in the pan and before you seal it close season the Oxtails with whatever you like,my mother used salt and a dash of paper and that's all.Make sure to over the top of the pan with foil because we want them Oxtails to sweat this is really the cooking process
-Place in a hot over at 300 or something close to that for 45-60 minutes and check to see if when you remove and you still feel a lot of water moving in the pan,let em stay 25-30 minutes longer because we want them moist but not soaking wet.
(-In here is the time you would add slightly cooked rice,boil the starsh off,let sit in warm water til time to add:Here is when you would add them to another pot and open a few cans of salted vegetable soup and let simmer for oxtail soup,you can also add unions and other things in here)
-After that there should be some fluid in the pan,maybe a cup full and after that take the foil off prepare to make your gravy with what you have and put back in the oven 15-20 minutes now we want them to dry out only on the top,browning the meat and just a little bit but no sticking at the bottom and you can stir em up.
Mind you this is how I see it done in my house by my mother,her mother and her mother but some might say it's some unnecessary steps but you will do whatever it takes so they taste good.Oxtails are a meal you cook on Saturday evening refrigurate overnight and serve on sunday for dinner......something you'll never forget.
