Part of the Prep and Production Cook track. Lesson 3 of 10.
Where in the shift: early, with cold product.
Prerequisites: Modules 5, 13, 14.
The sequence
Work cold.
Follow the seams.
Portion to a written standard.
Weigh as-purchased, usable, and trim.
Record it.
The decisions
How aggressively to trim. A yield decision and a cooking decision at once, per Module 13. Fat is insulation and removing it for appearance changes how the product cooks.
Whether to portion now or later. Portioned product has more surface area and a shorter clock.
And what goes in the trim bin versus what gets saved. Brisket trim is sausage material and rendered fat, per Module 52. A trim bin with usable material in it is a decision nobody made.
What you are reading
Fat firmness. Cold trims clean; warm smears — same mechanism as Module 37's sausage.
The seam, which separates muscles cleanly when followed and leaves meat behind when crossed.
And the trim bin itself. Muscle in the trim is the finding, and it is available for free.
What goes wrong here
Seams crossed. Yield below target with muscle in the trim.
Worked warm. Slow, torn, and smeared.
Yield never recorded — which means a six percent drop can happen without anyone knowing why, per Module 13.
Verification
Weigh the trim. That number is the verification and most kitchens do not have it.
The boundary
Raw protein handling and cross-contamination control are governed by the local health authority.
