Production identity
- Target finished yield
- 4 kg · approximately 20 portions at 200 g
- Reference ratio
- Finished mass ÷ declared primary-input basis (batch reference ratio): 100.0% (4 kg declared primary input → 4 kg finished target)
- Total formula input
- 3.95 kg before trim, evaporation, absorption or transfer loss
- Time
- 25 min active · 50 min total
- Equipment
- heavy sauté pans · silicone spatulas · scale
- U.S. major allergens intentionally present
- Egg, Milk
- Additional sensitivity note
- None listed.
- Holding / service
- Cook to order in small batches. Use pasteurized egg product for a soft-set service style under an approved food-safety plan.
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 |
|---|---|---|
| Pasteurized whole egg | 3.2 kg | |
| Butter | 450 g | |
| Crème fraîche | 220 g | finish |
| Kosher salt | 32 g | |
| Chives | 40 g | |
| Black pepper | 8 g |
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× |
|---|---|---|---|---|
| Pasteurized whole egg | 81.01% | 1.6 kg | 3.2 kg | 6.4 kg |
| Butter | 11.39% | 225 g | 450 g | 900 g |
| Crème fraîche | 5.57% | 110 g | 220 g | 440 g |
| Kosher salt | 0.81% | 16 g | 32 g | 64 g |
| Chives | 1.01% | 20 g | 40 g | 80 g |
| Black pepper | 0.20% | 4 g | 8 g | 16 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
Work in small enough batches that a cook can continuously control the whole egg mass rather than scraping a set skin from the pan.
Melt butter without browning, add egg and stir deliberately over low-to-moderate heat, sweeping corners and bottom.
Remove from heat before the desired final set because the pan and curd continue cooking from stored heat.
Fold in crème fraîche to cool and enrich the curds, then season and add chives only after texture is established.
Portion immediately onto warm—not scorching—plates; never place soft eggs into a long steam-table hold.
Working numbers
- Finished formula: 4.0 kg
- Pasteurized egg = 80% of formula
- Small-batch cooking is a capacity control
- Residual heat is part of the endpoint decision
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.

Sensory standard
Small glossy tender curds that mound but remain creamy; no whey puddle, rubbery sheets or browned egg flavor.
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 |
|---|---|---|
| Dry rubbery eggs | Cooking continued until fully set in pan | Pull earlier and account for carryover. |
| Watery weeping | Eggs held hot after cooking or salt/heat management poor | Cook smaller batches and plate immediately. |
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.
