What product is typically portioned using a pastry bag?

Using a pastry bag is a common practice for piping a variety of soft or semi-soft fillings and frostings. The sweet cream cheese filling is typically used in desserts like pastries, cupcakes, or cheesecakes, where precision in portioning and presentation is important. A pastry bag allows the user to control both the amount and the design of the filling applied, making it ideal for sweet cream cheese fillings which often require an aesthetically pleasing presentation.

While chocolate mousse and vanilla frosting can also be used with a pastry bag, the texture and consistency of sweet cream cheese filling makes it particularly suited to be portioned in this manner, as it often needs to be piped into or onto desserts. Fruit compote, on the other hand, is more liquidy and chunky, and is usually spooned or poured rather than piped, making it less appropriate for portioning with a pastry bag.
