## Goal
Let a second person repeat a substitution (for example, one fat for another in a bake) and judge the same things you judged.

## Prerequisites
A written base recipe with quantities by mass, and the ability to make two batches under the same conditions.

## Steps
1. Fix the control: the original recipe, weighed in grams, with oven type and temperature setting, pan material and size, and timings.
2. Change exactly one thing: the substituted ingredient, in the same mass or the ratio you decide to test; write the ratio down.
3. Bake or cook both batches in the same session, same equipment, same position; record actual times and any deviations.
4. Observe measurable properties first: mass before and after, height or spread in millimetres, internal temperature if relevant, browning described in plain words.
5. Only then record preference judgements, from at least two people, without telling them which batch is which if possible.
6. Report both batches side by side, with the limits of the comparison (one session, one oven).

## Expected result
A comparison another cook can repeat and extend, with observations separated from opinions.

## Limits and test basis
Template only; it asserts no outcome and gives no food-safety guidance. Equipment variation is a large uncontrolled factor between households.
