I do not add anything when I wrap.
I am assuming this is IBCA. Their rules as to what is acceptable is different from KCBS. It looks like 7 slices of brisket is what they like to see, although the rules say the promoter or head judge will give exact quantities to be turned in. Here is the IBCA rule on Judging Tray Contents.
9. JUDGING TRAY CONTENTS — IBCA requires that the promoter and/or Head Judge advise all cooks of the exact quantities and cuts of meat that will be placed in the judging trays. This will normally be accomplished at the cook’s meeting. The Head Judge or designated representative will inspect all trays at the time of turn-in in order to assure compliance with the turn-in criteria. All garnishes and condiments are prohibited, as they do not reflect the true quality of the cooked meat.
Meats may be cooked with sauces and/or other liquids, but once the cooking is complete, sauces and/or liquids may not be added once put into tray. NO PUDDLING IN BOTTOM OF TRAY.
Recommended amounts are as follows:
Brisket: seven (7) full slices approximately 1/4” to 3/8” thick
Pork Spare Ribs: seven (7) individual cut ribs (bone-in)
Chicken: 1/2 fully jointed chicken (to include a breast, wing with tip, thigh,
and drumstick, with skin on. (NO Cornish Game Hens)
Pork: Pulled, sliced, or chopped ( All trays will be turned in the same,
either pulled, sliced, or chopped as directed by Promoter and/or Head Judge.
If an event has 50+ teams, it is recommended that two (2) 1/2 chickens be submitted for judging and that the brisket and pork spare rib quantities be adjusted accordingly
