How to tell if ricotta is bad
Smell
Ammonia or a sharp sour smell beyond the cheese's usual aroma.
Texture
Slimy surface, or very dry and cracked all the way through.
Colour
Darkened or yellowed edges, or new colours that are not part of the cheese.
Mould
On hard cheese, cut 1 inch around the spot. On soft or shredded cheese, discard.
Ricotta past the expiration date
Unopened
FoodKeeper gives unopened ricotta 2 weeks in the fridge, counted from the day you buy it. "Best-by" and "sell-by" describe quality and stock rotation, not safety; only infant formula carries a federally required use-by date.
Opened
Once opened, the printed date no longer applies. Count 1 week in the fridge from the day you open it.
How to keep ricotta fresh longer
- Wrap in wax or parchment paper, then loosely in plastic, so it can breathe.
- Store in the cheese drawer or a lower shelf at 40°F (4°C) or below.
- Use a clean knife each time to avoid introducing mould.
