The hand-over-grid test
The hand test measures coal heat in seconds: hold your flat hand a hand’s width above the grid and count until you have to pull it away.
- Why
- Nobody has a thermometer at an open fire, and the colour of the coals says too little. The count is the one reading that works the same everywhere — and it stands on every recipe page here.
- How you know
- Two seconds is full heat, four is hot, six is medium, eight is gentle. If you fall between two stages, wait for the higher number.
How it goes
- Wait until there are no flames left and the coals have a grey coat.
- Hold your flat hand a hand’s width above the grid.
- Count until it gets too hot. That number is the coal stage.
- If it does not match, raise the grid or wait ten minutes — do not fan the coals.
