6 ways to automate hot holding temperature checks

#1 - Simple log

Who it's for: Single-site kitchens running their own hot holding without a second checker. No EHO pressure yet, just a need to record that hot-held food stayed at a safe temperature through service.

What it is: A hot holding temperature check is a record of the core temperature of each hot-held item, probed at intervals through service. This version keeps it to the four things that belong to every check: what the item was, and the core temperature at 2, 4, and 6 hours of holding. All four sit in one box, so each item reads as a single tracked record rather than four loose fields. The UK target is 63°C or above continuously, set by the Food Hygiene (England) Regulations 2006, with a single 2-hour grace period if food drops below.

In practice: A single-site pub running a 4-hour Sunday carvery uses this. The chef probes each hot-held tray (pork, gravy, veg) at the 2-hour mark, types "Roast pork", and records 67°C. At 4 hours they re-probe and add 65°C. At 6 hours they probe again and record 64°C. Each item gets its own box. The whole check takes seconds per tray and leaves a record that names every item and tracks its temperature across the holding window.

Why it works: The four inputs live in one box, so a temperature reading can never be saved on its own. The item name and the time-stamped readings are always captured together. That makes the record traceable later: if a customer reports illness, you can find the exact tray and the exact moment its temperature drifted.

Steps included:

• 1 grouped check (one box per item) holding: food item (text), temperature at 2 hours (number), temperature at 4 hours (number), temperature at 6 hours (number)
• Duplicate the box for each item held during the service

#2 - With guidance

Who it's for: Kitchens with new starters or a rota of staff who don't all know the safe holding temperature by heart, and want the check to teach as it goes.

What it is: The simple log with a guidance note added to the top of the box. The note states the 63°C minimum, the 2-hour grace rule if it drops below, and where to put the probe: the centre of the food, not the surface, not against the metal of the tray.

In practice: A gastropub running a hot carvery on busy weekends uses this. A new commis chef opens the check, reads the note, and knows before probing that the gravy needs to hold at 63°C or above and that resting the probe against the side of the bain-marie gives a false high reading. They probe the centre, record 67°C at 2 hours, and move on. No one had to stand over them.

What it adds to the simple log:

1. The 63°C target is on screen at the moment of the check, not in a training folder
2. Probe placement guidance cuts the most common false pass (probe against the metal of the tray)
3. The 2-hour grace rule is written down so staff don't have to remember it under pressure
4. New staff run the check the same way as the head chef from day one

Why it works: The guidance sits inside the same box as the readings, so staff see it at the moment they probe, not in a training session they have half forgotten. It turns the head chef's standard into a prompt that is always on screen.

Steps included:

• 1 guidance note (63°C target, 2-hour grace, probe placement)
• 1 grouped check (one box per item): food item (text), temperature at 2 / 4 / 6 hours (3 numbers)
• Duplicate the box for each item held during the service

#3 - With a signature

Who it's for: Multi-site groups, large care operators, and any operation where someone signs off the day's hot holding checks and the records have to stand up to an audit across sites.

What it is: The simple log with a signature captured at the end. The person running the check signs to confirm every item was held at a safe temperature through service. The signature turns a set of readings into a named, dated commitment.

In practice: A 30-site pub group running Sunday carveries across the estate uses this. Each kitchen's duty manager logs the hot-held items at 2, 4, and 6 hours through service, then signs off at the end. The group's food safety lead can open any site's record and see the items, the temperatures across the window, and the signature, all timestamped, without driving to the venue.

What it adds to the simple log:

1. A signature naming who confirmed the day's checks, not an anonymous log
2. Named accountability for each site's checks
3. A complete audit trail: item, three temperatures, and a named sign-off

Why it works: A signature turns a private set of readings into a record someone has put their name to. Nobody can later say the checks were not done or were done by someone else.

Steps included:

• 1 grouped check (one box per item): food item (text), temperature at 2 / 4 / 6 hours (3 numbers)
• Duplicate the box for each item held during the service
• 1 signature (sign-off)

#4 - With photo evidence

Who it's for: Carvery kitchens, buffet operations, care homes, and any business under EHO scrutiny that wants to show proof rather than ask an inspector to trust a typed number.

What it is: The simple log plus a photo of each item's probe reading next to the food. The photo is captured in the box at the time of the check, alongside the item name and the readings. A number typed into a log can be written from memory or rounded up; a photo of 65°C on the probe screen next to the pork is contemporaneous proof. For hot-held food across long service windows, that is the difference between a record and evidence.

In practice: A care home kitchen serving lunch from a hot trolley runs this. The cook probes the centre of the shepherd's pie at 2, 4, and 6 hours of holding, photographs the probe reading against the dish each time, and records 68°C, 65°C, 63°C. If the CQC or the EHO ever questions a meal, the kitchen can show the exact reading for that exact dish on that day.

What it adds to the simple log:

1. A photo of each item's probe reading, captured at the time
2. Proof that holds up to an inspector or an investigation, not just a number
3. A visual record of which item was probed, so a borderline reading can be traced to a real dish

Why it works: Evidence taken in the moment is far stronger than a number recalled later. The photo ties the temperature to the actual tray and the actual time, which is what an inspector or an insurer needs to see.

Steps included:

• 1 grouped check (one box per item): food item (text), temperature at 2 / 4 / 6 hours (3 numbers)
• Duplicate the box for each item held during the service
• 1 photo inside each box (each item's probe reading)

#5 - With Poppi checking the photo

Who it's for: Kitchens where the probe photo gets taken but nobody reviews it. Multi-site groups where head office can't look at every site's photos at each check.

What it is: A photo-checked check is the simple log plus a photo of each item's probe reading that Poppi (AI) reviews the moment it's saved. Poppi answers one question about each photo, set by you: does the probe reading show the item is at or above 63°C? A single named spot like a probe display is something an AI can actually judge, where a wide shot of the whole kitchen is not. If the answer is no, Poppi posts what it spotted to the team chat, so the problem gets fixed before everyone leaves.

In practice: A three-site pub group runs hot holding checks at 2, 4, and 6 hours. On a busy Saturday at the flagship site, the duty manager photographs each tray's probe reading as they go: roast pork, gravy, vegetables. Poppi reads the photos: all at or above 63°C. Verdict yes, and nothing changes. But on a rushed service, one photo shows the gravy at 59°C. Poppi answers no and posts the reason to the team chat ("The photo shows a reading below 63°C"). The chef rechecks and finds the bain-marie running cold; they fix it and retake the photo while still on shift.

What it adds to the simple log:

1. A photo of each item's probe reading that gets checked the moment it's saved, not just stored
2. A team chat message with Poppi's reason the moment a photo shows a reading below 63°C
3. The manager stops being the only person who ever looks at the probe photos

Why it works: The check happens in the seconds between the photo being taken and the kitchen moving on. That's the only moment the problem is still cheap to fix. A manager reviewing photos at the end of service can only record that something was wrong; Poppi catching it in the moment gets it fixed before the next customer's meal.

Steps included:

• 1 grouped check (one box per item): food item (text), temperature at 2 / 4 / 6 hours (3 numbers)
• Duplicate the box for each item held during the service
• 1 photo of each item's probe reading
• 1 Poppi decision (judges each photo against your question)
• 1 Poppi action (posts to the team chat if any photo shows a reading below 63°C)

#6 - With a team alert if the check is overdue

Who it's for: Busy services that run temperature checks on a schedule and need the checks finished before the next service starts, to protect food through the whole holding window.

What it is: An overdue-check alert is the simple log plus a Poppi (AI) action set to the workflow's deadline. If the temperature checks aren't finished by the time they are due, Poppi posts a message in the Pilla team chat so the checks get done before that window closes. It watches the deadline, so it catches the checks that quietly got abandoned when service was busy, not just the ones that never started.

In practice: A 50-seat carvery runs hot holding checks every 2 hours: at 12pm, 2pm, and 4pm. On a busy Saturday with a queue at the pass, it is easy to skip the 2pm check when the plates are flying. With this version, if the 2pm check isn't finished by 2:05pm, the team chat gets a message, so the senior chef catches the gap that shift rather than the health inspector catching it in an audit.

What it adds to the simple log:

1. A message in the team chat if the checks aren't finished on time
2. A catch for the checks that got abandoned when service got busy, not just the ones that were skipped entirely
3. A record of when the checks should have been done, next to when they actually were
4. The kitchen lead finds out that shift, not from a recalled gap at the next audit

Why it works: The alert is tied to the check deadline, so a missed check raises its own hand. Nobody has to remember to ask if the 2pm check was done; the clock does.

Steps included:

• 1 grouped check (one box per item): food item (text), temperature at 2 / 4 / 6 hours (3 numbers)
• Duplicate the box for each item held during the service
• 1 Poppi action (posts to the team chat if the check isn't finished by deadline)

How to pick the right version

You don't need to know our product to choose. Every version here is the simple log plus one addition, so pick the additions your kitchen actually needs.

Is it just you running the check, or do other people run it too?

If you run every check yourself and you know the 63°C target cold, a plain log is enough. The moment new starters or a rota of staff are probing the bain-marie, the target needs to live on the screen instead of in your head. If only you check, #1 is fine. If anyone else does, #2 adds a guidance note.

Does someone need to sign off the checks?

In a single kitchen, the records speak for themselves. Across several sites, an auditor wants to know who confirmed each day's checks. If no sign-off is needed, #1 or #2 is enough. If you run more than one site or answer to a food safety lead, #3 adds a signature so every site is accountable for its own record.

Do you need photo proof?

A record tells you a temperature was logged. Proof is something you can put in front of an inspector. If a written number is enough for now, skip this one. If you are under EHO scrutiny, run a carvery or buffet, or cook for vulnerable groups, #4 adds a photo of each item's probe reading captured at the time.

Does anyone actually look at the photos?

If a manager genuinely reviews every photo, #4's record is enough. If photos get taken and filed unseen, #5 has Poppi (AI) check each one as it's saved, and tell the team chat when something's wrong.

Do the checks have to be finished by a set time?

If your service has a set time when checks must be done and a busy shift sometimes leaves them half-finished, #6 posts a message to the team chat if the checks aren't signed off in time. If checks always get done, #1 to #5 are enough.

Need more than one addition? Open the version with the addition that matters most in the playground and add the others as steps. That's how the product works anyway: every option here is one step added to the same list.

Conclusion

Hot holding is the step where cooked food sits between the kitchen and the customer, and where temperature drifts quietly because nobody is watching the pass thermometer once service is busy. A recorded log turns "we hold food safely every day" into something you can show. Every version above is the same simple log plus one addition: guidance, a signature, a photo, an AI check on the photo, or a deadline alert. Pick the ones your kitchen needs and combine them in the playground.
