How long does it take to cook meat the size of half a baseball at 200 Celsius?

well you gotta figure your sauce wasn't 400F approx 200C, it will take time to reach that and if you expect your meat to cook up to 165 F then you have to admit the sauce to that temp which can make and most likely break a sauce and i dont mean fall apart, scalding a tomato i dont care for and breaks into different acid's not so tasty to me,,,,, cook your 1st,, i am a bake fan, but pan frying is just as great though different,,, i would suggest going through many processes untill i found my preference and keep it.. i write down my experiments as they go,, enjoy,, and dont be poisoning people,lol,, :)
