Part of the Pit Production Cook track. Lesson 1 of 10.
Where in the shift: before anything goes on, and continuously afterward.
Prerequisites: Modules 7, 12, 36.
The sequence
Check the fuel before you light anything. Wood condition, quantity, and whether it is what you have been using. A load that sat in the rain or came from a new supplier changes the cook and it changes nothing on the gauge.
Build the fire and let it establish. Not a smoldering start — a hot clean burn before anything else happens.
Bring the chamber to temperature and let it hold there for long enough that the walls and the fuel bed are at temperature, not just the air. The gauge is measuring air and the walls take longer, per Module 7.
Then load.
And manage across the cook with fuel quantity, not with the intake.
The decisions
How much fuel to start with. Too little and you are adding constantly, which means opening the firebox and disturbing the burn. Too much and you overshoot and then choke it down, which is how creosote starts.
Whether the wood is usable. This is a decision and most cooks do not make it consciously. Wet or unseasoned wood cannot burn clean regardless of airflow. If the fuel is questionable, the cook is compromised before it starts and it is better to know that at five in the morning than at two in the afternoon.
How to hold temperature when it runs high. Two options and only one is correct. Reduce the fuel, or close the intake. Closing the intake starves the fire and produces creosote, per Module 12 — and it is the natural move because it is faster.
Whether to open the door. Every opening costs recovery. The decision is whether what you will learn is worth what it costs, and the answer is usually no — most door openings are checking something that could have been checked at the next necessary opening.
What you are reading
The stack. Thin, barely visible, faintly blue is clean combustion. White, gray, or heavy is not. This is the single most informative observation available and it is free from anywhere in the yard.
The smell. Clean smoke smells sweet and mild. A starved fire smells sharp — and if it is on your clothes as harsh rather than sweet, the fire has been dirty for a while.
The fuel bed. Glowing evenly with light ash is right. Dark, smoldering, or heavily ashed over means it needs fuel or air.
The gauge, last. It tells you the air temperature and it does not tell you the fire's quality — a pit can hold a perfect temperature while burning badly, per Module 36, and that is the sentence this lesson exists for.
What goes wrong here
The starved fire. Temperature held by closing the intake. Creosote deposits across the cook. The result appears at slicing as bitter, acrid bark worst at the fat edge — and the kitchen reformulates the rub for months.
The unrecovered load. Product on before the walls and the fuel bed are back. The first hour happens in a different environment than planned and nothing on the gauge shows it.
Wet or unfamiliar wood used without checking. Not recoverable once the cook is running.
Verification
Someone else can look at the stack and tell you what they see. If the smoke is heavy and the cook says the pit is holding temperature, that is the finding.
And the intake position over the cook is observable. A pit run with the intake progressively closing is a pit being managed the wrong way, and it is visible without asking anyone anything.
The boundary
Fire, fuel storage, and outdoor cooking equipment carry fire-safety requirements governed by the applicable fire authority. Nothing here addresses those.
