Okay, so I am getting 4 1/2 racks of ribs onto the smoker today in preparation for day after Christmas dinner. I rubbed them all up last night and let them sit in the fridge till now. One of the slabs of ribs on the bottom/membrane side has a blueish tint to it and just doesn't look right. Everything smells fine but I'm thinking I should probably just throw out this entire slab. What do yall think? I don't want to chance getting guests sick. So that would leave me with 3 1/2 racks in the smoker and another 1 1/2 for the oven for 6 adults and 5 little ones (oldest is six). With everything else we will have I'm pretty sure we will still make out alright for dinner.
