Freshly whipped cream is a game changer for just about any dessert, pastry or coffee drink. Just be aware that whipping cream can sour and spoil if stored in a place that's too warm or kept past its expiration date. Before you whip it up, check to make sure it's still good to go.
Check the expiration date on the carton of whipping cream. If it's kept closed in the refrigerator at or below 40 degrees Fahrenheit, the cream may last for one week past that date and is usable as long as it does not taste or smell sour.
Smell the whipping cream. Soured cream has a distinctive smell as bacteria starts eating away at the components and the milk fat starts to oxidize. Usable whipping cream has a mild, milky smell, and spoiled cream smells rancid.
Dip a finger into the whipping cream and taste a little bit of it. Do not take any more than a very small taste, as you don't want to ingest any harmful bacteria. Soured cream tastes bitter and definitely won't be palatable as whipped cream.
