Hello and Help!!! I am a cook at home and have been given a huge assignment. I have in my refrigerator 13 whole beef tenderloins that I must cook for a church group for tomorrow. I have one oven but it can turn into a convection oven if needed. My question is: should I use the convection oven and can I cook 4 at a time? or perhaps I should ask: How is the best way to complete this assignment? I am the only person available so I can not ask others to help, I've tried. I have looked up recipes that say to use the convection for baking rather than roasting as it makes meat rubbery. With this much meat, I don't want to fail and would love some input. Thank you.
