How do you keep marshmallow crème safe to eat?
- These times assume the fridge is at 40°F or colder and the freezer at 0°F.
- Freezer times are for best quality. Food kept frozen at 0°F stays safe indefinitely; it just loses flavor and texture over time.
- Perishable food shouldn't sit at room temperature for more than 2 hours (1 hour above 90°F).
- Smell and looks don't tell you about the bacteria that make people sick, so go by the time, not by a sniff test.
Never guess again. Add food to your pantry in Pantry to Pan and it tracks
how long each thing keeps, then shows what to use up first.
