Week 11: Cooking
The same dish, cooked twice from batches of material prepared two different ways, so that any difference in the result can be attributed to the preparation rather than to what happened at the stove.
3 May 2027
Ten weeks of this course have been preparation without heat. This week is the first to use it, and it uses it as an instrument rather than as the subject: the question being tested is whether preparation, not technique, decides the result.
The design#
Each pair or small group is given two batches of the same raw material, prepared two different ways upstream — one following the standards this course has taught since week 2 (correct storage temperature, a clean cut from week 7’s grip and edge work, correct cold-chain handling from week 10), the other deliberately departing from one of those standards in a single, stated way. Everything downstream of that difference is held identical: same recipe, same heat method, same time, same person cooking both. Heat is covered only as far as this comparison needs — enough to finish the dish correctly, not as new material in its own right.
Doneness is checked, not guessed#
A thermometer decides when a batch is done, against the same minimum internal temperatures used throughout the course’s storage material: roughly 63 °C for a whole cut of beef, pork, lamb or veal, 74 °C for poultry, and higher for ground meat, because grinding distributes any surface bacteria through the whole piece rather than leaving it on a surface a sear can reach. Colour and time are both unreliable across the two batches in this exercise for the same reason they are unreliable generally: they describe the outside of the food, and this week’s variable often is not on the outside.
What is compared#
The two finished dishes are compared on the same terms an earlier assignment already predicted a dish on — colour, aroma, flavour, texture — but the question here is narrower: which of those differences, if any, can be traced to the stated preparation difference rather than to anything that happened after the pan was hot. A group that finds no difference has also learned something, provided they can say which preparation variable they tested and why it turned out not to matter this time.
Afterwards#
This is the first week the course’s central claim is checked against an actual result rather than argued from storage temperatures and figures. Week 12 checks it again, once, under conditions this session does not have: a stated time limit and an audience.
Outline#
- the design: two batches, one stated preparation variable held apart
- doneness checked by thermometer against a stated minimum internal temperature, not by colour or time
- what is compared, and what counts as a result worth attributing to preparation
