The consistency of heavy cream refers to its thickness and viscosity. Heavy cream is a type of dairy product that has a high fat content, typically around 36-40% butterfat. Due to this high fat content, it is thicker and more viscous than other types of cream such as light or whipping cream. The consistency of heavy cream makes it ideal for use in recipes that require a rich and thick texture, like desserts or sauces. It can also be used to make whipped cream by simply whisking it until it becomes fluffy and light.
