When food sits on a table for an hour, it cools. A food warmer keeps it properly hot, which matters for taste and for safety.

What to check

- Temperature control on electric trays.
- Fuel type for chafing dishes, and how long each burner lasts.
- Cool-touch handles and a stable base.
Keeping it safe
Warmers are for keeping hot food hot, not for heating cold food. Put food on them already steaming hot. The Food Standards Agency describes 8°C (46°F) to 63°C (145°F) as the danger zone, so food that has cooled into that range should not be left sitting out.
