Thanks for the welcomeHi and Hello Mezzaluna, Must tell you that I am not involved with any establishment in the food or catering professions.
I was searching the web looking for the answer to my query as I am housebound most of the time having been physically disabled for over 60 years and have had 7 heart attacks plus other illnesses mostly when I am able I use my motorised wheelchair to get out on sunny days which as you know England is not that often.
I only wanted to find out how I could roast an Ox heart as I thought it would be a change to have Ox heart for next Sundays main midday meal instead of all the other meats I have tried. So now you see what I have gotten myself into for just asking for help in this respect :)
Oh and Thank you for the welcome, I hope you enjoy this site :)
