Signs Sour Cream Has Gone Bad
- ⚠️ Mould of any colour on the surface
- ⚠️ Strong or unpleasant sour smell beyond normal tang
- ⚠️ Yellow or off-colour tinge
- ⚠️ Very watery separation with off smell
Sour Cream Storage Tips
- Always use a clean spoon to avoid introducing bacteria
- Press plastic wrap onto the surface before sealing the lid
- Check the sell-by date before purchasing
- Do not leave at room temperature for more than 2 hours
- Discard if you see any mould — do not scoop around it
⚠️
The watery liquid on top of sour cream is whey — it is safe to stir back in. Mould, however, means the entire container must be discarded.
