Whipping cream and heavy cream are not always the same thing.
The USDA regulates how much fat must be in certain dairy products sold in the US.
By law, to be called "heavy cream" a cream must have at least 36% milkfat and can have more.
By law, "light whipping cream" must have at least 30% but less than 36% milkfat.
"Light cream" (sometimes called "coffee cream") must have at least 18% milkfat, but less than 30%
"Half and Half" must have at least 10.5% milkfat, but less than 18%
From a practical standpoint, both light whipping cream and heavy cream will whip up just fine, though heavy cream does so more easily and will be richer in consistency.
Less is not more. More is more and more is fabulous.
