The recipe says the dish will keep for up to a week after it's cooked. So I think cooking it Thursday night and serving Saturday morning will be okay. I will cook it all the way through.
There's no additional help. DH is sick, DS1 is away at school, and DS2 is helping with all the other set up for the tournament. We're expecting almost double the number of competitors this year over last year so everyone is in a panic. My plan is to take care of my assigned tasks and stay out of everyone else's way. Saturday is going to be *heck*.
