Write it down. Make the next cook better.

A notebook with a purpose

A cook log is most useful when it helps you make the next decision. It does not need to record every second. It needs to preserve the details that would otherwise turn into “about this much” and “roughly that long”.

This is a blank framework for future cooks, not a report of an experiment we have already run. Copy the headings into a notebook before starting, then add observations as they happen.

Start with one question

Write a question you can answer from the session. If you are comparing approaches, choose one main thing to change and list what you intend to keep the same. Record anything else that changes anyway — a different cut size, a weather shift or an interrupted cook may explain part of the result.

A single comparison suggests what to investigate next. It does not establish a universal winner. Keep that limit beside your conclusion, especially if you later turn the notes into a recommendation.

The starting record

• Cook reference and actual date; the question you want to answer.
• Meat type and the supplier's cut name; whether it is bone-in, boneless, rolled or otherwise prepared.
• Purchase weight, trimmed weight and cost in £; keep the receipt or purchase record.
• Smoker make and model, setup, fuel and wood; record quantities and units rather than “a handful”.
• Seasoning ingredients and amounts in grams; any recipe or method used, with its source.
• Weather observations and the location of each temperature probe.

Keep the planned values separate from the observed ones. “Target chamber temperature” and “measured chamber temperature” should have their own entries. An unreadable photograph or a lost reading is a gap to mark, not a number to reconstruct.

Keep a short event timeline

For each meaningful event, record the time, chamber temperature in °C, internal meat reading where relevant, the action taken and the reason. Events might include placing the meat, adding fuel, changing a setting, wrapping, removing it, resting and serving.

Record fuel additions by weight if you can measure them consistently. Keep fuel added separate from fuel actually consumed; leftovers and ash make those different quantities. Note which measurements are estimates.

Photograph the setup, probe position and finished result when it is safe to do so. Give each photograph a filename or reference in the notes. Photographs can show what happened; they cannot replace temperature measurements or food-safety checks. Use our planning checklist alongside a suitable method.

Weigh what you mean

For a yield calculation, label both measurements clearly. If you compare raw purchase weight with finished edible weight, say that the result includes trimming, cooking losses and anything discarded. If you want cooking yield alone, begin with the prepared raw weight. Use the same definition on later cooks.

For costs, separate the meat from fuel, seasoning and sides. A meat-only cost per portion is not the total cost of feeding somebody. Record how many portions were actually served and what was left, rather than assuming every cook feeds the same number.

Describe the result before scoring it

Use observations another person could understand: which part was dry, how the surface felt, how the slice held together, or whether the seasoning seemed balanced to you. Note when you tasted it and who contributed an opinion. A score out of ten is more useful after that description than on its own.

Finish with three short entries: what worked, what remains uncertain and one change for next time. Keep the original notes when writing a polished article, and record later corrections rather than silently replacing inconvenient results.

Publishing a real experiment

Before calling an entry a cook log, check that its measurements, photographs and conclusions all belong to the cook described. Say whether the result was repeated, whether equipment was borrowed or supplied, and whether any links can earn commission. Research and predictions should be labelled separately from observations.

That is the standard we are setting for The Smoke Lab. The blank record comes first; the evidence has to follow.
