Cold Chain teaches the numbers; this teaches the tool that reads them. New kitchen staff meet the probe thermometer here — turn it, zoom it, learn its parts — before they're asked to trust it over the shift clock. Spatial familiarity with equipment is a learning objective too, and screenshots don't teach it.
The sensor is in the tip, not the shaft — insert to the dimple, into the thickest part of the food, never touching the pan.
Wait for it to settle — the number that matters is the one that stops moving, not the first one you see.
In production this pairs with hotspot questions ("tap where the sensor is"). Spatial recall beats photo recall when the real object is in your hand.
