I know how to roast beef in the correct way and let it rest before slicing, without wrapping it and making it sweat etc. etc.
My question is though that I'm roasting beef to take to a friends for dinner and I'm worried that after cooking if I transport it in a tupperware or something while warm, it will sweat and dry out and maybe even over cook. Do you think the best option after resting is to slice the entire thing and let it cool before transporting then just serving it cold at the other end?! Reheating the meat the other end will obviously over cook it...
