What that means
This keeps longer, but cold storage and clean handling still matter.
Use this as a planning window, then check the real-world spoilage signs below before eating.
Make Sublime Myrtille last the full window
Do
- Refrigerate promptly after each use, at 5°C / 40°F or below.
- Use a clean utensil every time you take a portion.
- Keep it sealed — the original lid or an airtight container.
- Freeze it before the window closes if you will not finish it — Transfer the spread to an airtight container and freeze for up to three months.
Don't
- Leave it out on the counter while cooking or serving.
- Double-dip or return unused portions to the container.
- Store it in the fridge door if you open the fridge often — it is the warmest spot.
- Taste it to "test" safety. If in doubt, throw it out.
