Simply from looking at the pix:
Garnish isn’t judged. It needs to be legal (parsley, kale, green lettuce, …) but it’s just to keep the meat from sliding around.
Smoked turkey breast, sliced, on pretzel buns, cranberry sauce, and some kind of spread I can’t make out. The turkey slider I judged had a layer of stuffing. The other turkey entries I got were slices of white meat.
Chicken thighs: thighs are typically turned in and almost always look just like this. I’ve seen a steady pattern of drumsticks the last few years, but it’s probably 5:1 thighs. Yesterday I got a box of thighs and wings. But they are always shined up like this. After cooking they get dunked in sauce and put back on the smoker another 5-10 minutes.
Ribs: St Louis cut spares.
Pork: that would be a money muscle and “tubes”. Many teams cook a pork collar, a specifically trimmed pork butt that pretty much just includes those two muscle groups. This is where I disagree with the current KCBS rules, I prefer the old rules that required a whole butt.
Brisket: Josh (JD), and the other top teams believe in “go big or go home” and will spend around $200 for a Wagyu brisket flat that’s the perfect size to fit that box. The slices are soaked in the juice before boxing.
A lot of teams are cooking in drum smokers, hot and fast. It’s efficient, consistent, and makes for an easier cook. The side effect is the brisket gets that dark roasted look.
Another thing I’ve been seeing recently is burned sauce. Teams new to the drum forget how hot they cook will put the chicken and ribs back on in order to set the sauce and then burn it on the bottom. They may not even notice. But the judges get a bite of that bitter, burned sugar and mark down the taste score.
