Ice Cream Composition
- Ice cream in the U.S. must have at least 10% milk fat, derived from cream.
- Other key components include ice crystals, air, sugar, and sometimes eggs or chocolate chips.
Ice Cream Microstructure
- Ice cream's texture and taste arise from its "microstructure."
- This structure is a "frozen snapshot" of fat globules, ice crystals, air, and other ingredients.
Overrun and Ice Cream Texture
- "Overrun" refers to the amount of air incorporated into ice cream, impacting texture.
- Premium brands often have lower overrun (denser) and higher milk fat than store brands (fluffier).
