Why frozen desserts melt differently

Two frozen desserts can soften at different rates because their formulations, structures, serving temperatures and surroundings are different.

Temperature is only the beginning

A dessert begins changing as heat moves from the air, container, utensil and nearby surfaces into the product. Direct sun, a warm car and a warm serving dish accelerate that transfer.

Composition changes texture

Water, dissolved sugars, fat, milk solids, fruit solids, air and other ingredients influence how much of the product is frozen at a given temperature and how the structure behaves as ice melts.

Air and structure

Some frozen desserts contain more incorporated air than others. Ice-crystal size and the network surrounding those crystals also affect firmness, smoothness and how the product collapses while warming.

What customers can control

Keep the trip short, use an insulated container with cold sources, avoid repeated warming and refreezing, and serve promptly. These steps protect quality without promising an exact melt time.
