Reasons for watery whipped cream
Watery whipped cream is most often due to over-whipping, usually when we break through a critical point in the whipped cream may lead to the phenomenon of separation of oil and water in the cream, which is what we call "watery".
In addition, if the cream is stored in a place where the temperature is too low, it will also lead to the separation of oil and water, which we often say that the cream is "frozen". It's hard to get the cream back to its original state when it's separated from the water, so we have to be careful with it.
Usually when we save the cream, you can put it in the refrigerator, do not freeze. And in the whipping cream can be in the cream container under the point of a pot of ice water, while the cream whipped to the right degree should be quickly stopped, or a few minutes more may be too much.
