Part of the Pit Production Cook track. Lesson 5 of 10.
Where in the shift: when the bark is set, which is not a time.
Prerequisites: Modules 8, 12, 36.
The sequence
Touch the bark.
If a fingertip does not mark it, wrap.
If it marks, wait and check again.
The decisions
When. The trigger is bark state and nothing else — not a temperature, not a clock, not the stall breaking.
Because wrapping stops evaporation, per Module 8, and that is its entire thermal function.
Wrap on a set bark and it is preserved while the finish accelerates. Wrap before it sets and it never will.
Whether to wrap at all. A legitimate decision. Unwrapped produces a firmer, drier bark and a longer cook with more moisture loss. Wrapped produces a softer bark and a faster finish with more retention.
Both are defensible and the room should decide which it wants rather than doing whatever the last cook did.
What to wrap in. Paper breathes and preserves more bark texture. Foil seals and accelerates more. A house decision, and it should be consistent.
What you are reading
The fingertip test. Firm, dark, and it does not mark. That is the standard and it is tactile.
Almost-right: dark and a fingertip leaves a faint mark. Slightly tacky rather than firm. This is the moment before, and wrapping here is the difference between firm bark and soft bark at service.
And the color, which is supporting evidence rather than the trigger — bark can be dark and not set.
What goes wrong here
Wrapped by number. "Wrap at a hundred and sixty" is folklore — the number describes when bark is often ready and the bark describes when bark is ready.
Wrapped early to break the stall. Soft, tacky bark at service.
Not wrapped when the schedule required it, which is a scheduling failure showing up as a technique decision.
Verification
Ask what the trigger was. If the answer is a time or a number, that is the finding, per Module 53.
And ask whether they touched the bark. Most cooks who wrap by number have never touched it.
The boundary
None specific beyond the general food safety framework.
