I've got one from last weekend. I provided the recipe for Mojo marinade,...
...which is a family favorite, to some friends. They are not cooks, but the Dad will grill if he has to.
He was cooking the chicken on the grill when he picked up the ziplock bag that was now empty of chicken, but held the used marinade and started to drizzle it over the chicken. He then proceeded to start taking the chicken off the grill and put it on a platter.
I had to stop him and let him know he had to bring all that drizzled marinade up to temp or he might make someone sick. He hadn't thought of that.
I told him that if he wanted to drizzle, he would be safer making a double batch of marinade and setting half aside for that purpose, never having touched raw chicken. Or, he could reserve a small amount from the original batch BEFORE he put the raw chicken in it. Either way.
Yowza!
