Training the Sensory Standard

The sequence

Build a reference sample.

Build a fault sample where possible.

Taste them side by side.

And name the almost-right.

The decisions

Whether to create faults deliberately. Yes, where it is safe and legal to do so — because reading about a fault teaches almost nothing and tasting one teaches it permanently.

Over-toast a chile. Hold a gravy past its window. Warm a biscuit dough on purpose.

And whether to teach the discrimination. This is the highest-value content in the lesson — over-worked eats tough and pulls; warm-fat eats dense and crumbles. Both look flat and they have opposite fixes, and changing the wrong one costs a week.

What you are reading

Whether the trainee can distinguish two failures that look alike.

What goes wrong here

Faults described rather than tasted.

And discriminations taught as descriptions rather than as side-by-side comparisons.

Verification

Present two look-alike failures and ask which is which.

The boundary

Any deliberate fault creation must comply with the local health authority's requirements, and faulted product is not served.
