Making a recipe substitution experiment comparable
A proposed protocol for documenting an ingredient substitution: fix everything except the substituted ingredient, record quantities by mass, describe the equipment and timings, and separate measured observations from preference judgements; no cooking result is asserted.
Contents
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
- Fix the control: the original recipe, weighed in grams, with oven type and temperature setting, pan material and size, and timings.
- Change exactly one thing: the substituted ingredient, in the same mass or the ratio you decide to test; write the ratio down.
- Bake or cook both batches in the same session, same equipment, same position; record actual times and any deviations.
- Observe measurable properties first: mass before and after, height or spread in millimetres, internal temperature if relevant, browning described in plain words.
- Only then record preference judgements, from at least two people, without telling them which batch is which if possible.
- 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.
