Can it sit out?
Olive and vegetable oil is shelf-stable, so sitting out at room temperature isn’t the safety question — storage time is.
How to tell if olive and vegetable oil has gone bad
- A waxy, crayon smell instead of a clean or grassy one
- A bitter, scratchy burn at the back of the throat
- Cloudiness or sediment that won’t clear at room temperature
- A sticky, varnished film around the neck of the bottle
When in doubt, throw it out.
Keep it in a dark cupboard away from the range — heat and light age an oil faster than the calendar does.
