Cream
Learn the culinary uses, pH levels, and storage qualities of cream for everyday cooking.
Classification: Heavy lipid dairy emulsion (min. 36% butterfat)
pH Level: 6.5 - 6.8
The high-fat lipid portion of milk, concentrating dairy butterfats to provide extreme silkiness, viscosity, and whipping stability.
Common Culinary Roles
- ⯅Silkiens pan sauces and velvety vegetable soups.
- ⯅Whipped mechanically to trap air pockets for frostings and mousses.
- ⯅Creates smooth chocolate ganaches and rich custard bases (crème brûlée).
Storage Guidelines
- ▪Refrigerate below 40°F (4°C) and consume within 7 to 10 days of opening.
- ▪Never freeze if you intend to whip it later, as ice crystals break the fat membrane.
- ▪Keep closed to avoid absorbing food odors from cut onions or blue cheeses.
Cooking Behavior & Heat Reactions
Cream relies heavily on fat content. Whipping cream (~36% fat) traps air within solid lipid particles when chilled below 40°F (4°C). Under heat, cream resists acid curdling because of high fat-to-protein protective shielding.

Cooking Standards FAQ
Q:Why does cream whip but normal milk will not?
Whipping requires at least 30% fat. Mechanical whipping knocks fat globules out of their membranes, staying together to form a stable lattice that traps tiny air bubbles. Milk fat levels are too low to form this structural barrier.
Q:Why does my whipped cream sometimes turn grainy and watery?
Over-whipping causes fat particles to clump together too much. Eventually, they fuse completely into solid butterfat, squeezing out the trapped water liquid (buttermilk).
