One of the bakers that Kleiman was interviewing for her summer "pie-cast" series mentioned using something called manufacturing cream to make all of her whipped cream. She describes it as making the thickest, creamiest, and longest-lasting whipped cream imaginable. Kleiman immediately jumped in, confessing that her restaurant buys it by the case.
Manufacturing cream is nothing fancier than regular cream with a higher butterfat content (40% or more!) than even the heavy cream normally found in stores. This butterfat is the key to long-lasting whipped cream, since it forms a more stable molecular structure.
You can find manufacturing cream at Costco and Smart & Final stores. Some local dairies may carry it too, so ask around!
Have you ever used manufacturing cream in your cooking?
