A cooking record with timer and thermometer side by side: elapsed time and probe reading at fixed checkpoints

Goal

Keep, for dishes cooked repeatedly, a record in which the clock and the thermometer are logged together, so that "how long it took" and "what the probe read" can be compared across sessions instead of being remembered as one number.

Prerequisites

A kitchen timer and a probe thermometer whose type is known. The USDA FSIS page on food thermometers describes the types: dial thermometers must be inserted about 2 to 3 inches into the food because the sensing area runs along the stem; digital thermistor instruments sense in the tip and take roughly 10 seconds to register the temperature on the display; thermocouple instruments are described as displaying the final temperature fastest. The type decides where the probe reads and how long a reading takes to settle, so it belongs in the header.

Steps

1. Header per dish: dish, recipe reference, cookware, heat source and its setting as written on the dial, the thermometer type and model, the insertion depth and position used (for example "centre of the thickest part, from the side"), and the timer used.
2. Per session: date, the starting mass or count of the food, its starting temperature if measured (fridge or room), and the kitchen's air temperature if available.
3. Define the checkpoints before starting: fixed elapsed times (for example every 5 min) or fixed events (lid off, turned, removed from heat). Write the list in the header so that every session uses the same ones.
4. At each checkpoint write the elapsed time from the timer and, immediately after, the thermometer reading with the seconds it took to settle; note the probe position if it differed from the header.
5. Log the end of cooking as an event with both values, and note which signal the cook actually acted on: the timer rang, the reading was reached, or the appearance.
6. Never back-fill a missed checkpoint; leave it blank and mark the row partial.

Expected result

A per-dish table in which each session is a sequence of (elapsed time, reading) pairs at the same checkpoints, so that the spread of readings at a given time, and of times at a given reading, is visible across sessions beside changes in mass, starting temperature or heat setting.

Limits and test basis

Proposed protocol; no cooking time, temperature or relation between the two is claimed. The record says nothing about whether food is done or safe; it gives no target temperature and no cooking advice. Dial and tip-sensing digital instruments read at different places and are logged with their type. A thermometer's offset (see the ice-water bath record) is logged beside the series, not applied to it.
