Production identity
- Target finished yield
- 3.2 kg · approximately 20 portions at 160 g
- Reference ratio
- Finished mass ÷ declared primary-input basis (batch reference ratio): 80.0% (4 kg declared primary input → 3.2 kg finished target)
- Total formula input
- 4.107 kg before trim, evaporation, absorption or transfer loss
- Time
- 20 min active · 45 min total
- Equipment
- heavy sauté pans · sheet rack · thermometer
- U.S. major allergens intentionally present
- None intentionally declared in the formula; supplier labels and cross-contact still require verification.
- Additional sensitivity note
- None listed.
- Holding / service
- Cook to order; rest briefly, slice and serve. Do not hot hold sliced breast.
Raw-animal-food control: where this formula includes raw animal food, use the current authority-approved cooking time/temperature and the venue’s approved procedure. Sensory doneness never substitutes for a required food-safety endpoint.
Formula — 1× target batch
| Ingredient | Weight | Specification |
|---|---|---|
| Duck breasts | 4 kg | skin on |
| Kosher salt | 60 g | |
| Black pepper | 12 g | |
| Thyme | 15 g | |
| Garlic | 20 g | crushed |
Scaling table
Use the input-percentage column to audit transcription. The ½× and 2× columns scale ingredient mass only; process capacity must be revalidated.
| Ingredient | % of input mass | ½× | 1× | 2× |
|---|---|---|---|---|
| Duck breasts | 97.39% | 2 kg | 4 kg | 8 kg |
| Kosher salt | 1.46% | 30 g | 60 g | 120 g |
| Black pepper | 0.29% | 6 g | 12 g | 24 g |
| Thyme | 0.37% | 7.5 g | 15 g | 30 g |
| Garlic | 0.49% | 10 g | 20 g | 40 g |
Ingredient weights scale arithmetically; pan geometry, heat input, evaporation, fryer recovery, mixing shear, proofing/bake behavior and holding capacity do not. Revalidate process whenever batch size or equipment changes.
Method
Score skin shallowly without cutting flesh; season and start skin-side down in a cool-to-moderate pan so fat renders before skin burns.
Drain excess rendered fat as needed while maintaining skin contact and gradually increasing heat to crispness.
Turn briefly to finish flesh side; use controlled endpoint appropriate to product/safety standard.
Rest skin-side up so crust stays crisp and carryover stabilizes the center.
Weigh cooked yield, slice across grain just before service and use rendered duck fat as a separately controlled kitchen product.
Working numbers
- Target cooked yield: 80%
- Slow render precedes final crisping
- Rest skin-side up
- Rendered fat is measured secondary yield, not waste
Production verification
- Record actual finished batch weight before portioning; compare with target and investigate material variance.
- Record actual portion count and portion mass during service rather than inferring count from target yield.
- Verify current supplier labels for major allergens and document cross-contact limits of the actual station/equipment.
- Record the process/temperature checkpoints that are critical to this formula under the venue’s approved food-safety procedure.
- Taste or otherwise evaluate the formula at its actual service temperature and after the realistic hold/travel interval.
Batch record: target yield ____ · actual yield ____ · actual portions ____ · critical process checkpoints ____ · service hold ____ · waste/rework ____ · sensory result ____ · corrective action ____.
Sensory standard
Thin crisp rendered skin, moist rosy-to-house-standard interior, clean duck aroma, no thick rubbery fat layer.
Evaluate the control batch at pickup and again after the realistic handoff or hold. The written standard should describe the point at which the formula is still sellable and the point at which it must be remade, repurposed under an approved plan or discarded.
Failure laboratory
| Failure | Likely mechanism | Correction |
|---|---|---|
| Rubbery skin/fat | Pan started too hot and browned before rendering | Start cooler and render gradually before crisping. |
| Dry breast | Flesh-side exposure/endpoint too high | Shorten finish and account for carryover during rest. |
Version control
KECB professional training formula; validate local regulatory requirements, supplier specifications and venue procedures before production. A measured correction to the recipe becomes a documented formula revision after a controlled test; do not let different cooks maintain invisible personal versions.
