Nacho Cheese Sauce — retrospective whole-Recipe report

Hypothesis

Retrospective review expectation stated at recording time: the complete recorded formulation and Method can reach its intended endpoints and produce the following finished dish: Smooth, pourable cheddar sauce stabilised with sodium citrate for clean reheating. This is not a hypothesis documented before historical cooking and is not itself an observed outcome.

Procedure

This record was written on 2026-10-02 from Carlo Kruger’s retrospective report on that date. Historical cooking dates and trial counts were not recorded. The exact whole Recipe Version is Nacho Cheese Sauce v1. Its preserved source is recipes-tmp/nacho-cheese-sauce.md with SHA-256 e5802f6d683cc627f742d8008ce311a28ba099550154bdb72819d3ef5485a939. The serialized draft SHA-256 is e99533f7f026ddcf65bf3113994d09d73ccc0f53c47e6f068fbb4be9474a3f0c. The complete formulation and work sequence below are the recorded specification, not newly observed timings, temperatures or yields. Correspondence to past cooking is attributed to Carlo’s statement that the recipes as recorded were fully tested. The historical reconstruction caveats remain in the unchanged source; Carlo’s 2026-10-02 acceptance applies to this formulation and the packet’s explicit clarifications.

PHASE A — BASE

Ingredient Uses

Key	Ingredient	Quantity	Scaling	Use
whole-milk	Whole milk	250 g	62.50%	Whole milk.
sodium-citrate	Sodium citrate	10 g	2.50%	Sodium citrate.

Method

1. Combine milk and sodium citrate in a saucepan.
2. Heat to 75 C–80 C, whisking until the sodium citrate dissolves.

Phase Outputs

Key	Phase Output	Description
heated-milk-base	Heated milk base	Prepared intermediate for a later Phase. Use all.

PHASE B — EMULSION

Ingredient Uses

Key	Ingredient	Quantity	Scaling	Use
cheddar-finely-grated	Cheddar, finely grated	400 g	100.00%	Cheddar, finely grated.
pickled-jalape-o-brine	Pickled jalapeño brine	25 g	6.25%	Pickled jalapeño brine.
smoked-paprika	Smoked paprika	2 g	0.50%	Smoked paprika.
garlic-powder	Garlic powder	1 g	0.25%	Garlic powder.
cayenne-pepper	Cayenne pepper	0.5 g	0.13%	Cayenne pepper.

Method

1. Add cheddar in four additions, blending or whisking each addition smooth before adding the next.
2. Blend in jalapeño brine, paprika, garlic powder, and cayenne.
3. Hold at 60 C for service, or cool rapidly and refrigerate.

Phase Outputs Used

Phase Output	Use
Heated milk base	Use heated-milk-base. Use all.

Phase Outputs

Key	Phase Output	Description
cheese-emulsion	Cheese emulsion	Prepared intermediate for a later Phase. Reheat the prepared sauce gently if cooled; otherwise serve at the stated holding temperature.

PHASE C — REHEAT

Method

1. Reheat gently to 65 C while stirring. Add 10 g–30 g milk if the sauce is too thick.

Do not boil after adding cheese or the emulsion may become grainy.

Phase Outputs Used

Phase Output	Use
Cheese emulsion	Use cheese-emulsion. Reheat the prepared sauce gently if cooled; otherwise serve at the stated holding temperature.

Results

Carlo retrospectively reported that the recipes as recorded were all successful and fully tested, and approved this whole formulation for production. No further Recipe-specific observations were supplied. Cooking dates, trial counts, detailed tasting notes and instrument measurements were not supplied. Source yields are estimates, not measured results of this retrospective record. Recorded alternatives have no separate variation-specific testing observations in this report.

Decision

Carlo accepted the formulation as recorded, including the explicit reviewed clarifications, for production in the complete 25-Recipe batch on 2026-10-02. Proceed to normal exact-version Promotion after valid serialization, applicable Curation and reference resolution. Technical validation does not perform that human acceptance. A materially changed formulation needs its own exact-version evidence and acceptance; this report does not automatically follow future changes.
