Can it sit out?
Homemade salad dressing is perishable — the FSIS 2-hour rule applies.
Perishable food left at room temperature for more than 2 hours should be thrown out — 1 hour if it’s 90°F or hotter (a picnic, a hot car, a summer kitchen).
How to tell if homemade salad dressing has gone bad
- A rancid, crayon-ish smell off the oil
- Cloudiness or fuzz gathering around the garlic and shallot bits
- A slick, ropy pour it never had on day one
When in doubt, throw it out.
Olive oil goes solid in the cold — give the jar ten minutes on the counter and a shake rather than a spin in the microwave.
