Can You Freeze Half-and-Half?

Half-and-half sits in an odd middle spot for freezing — its fat content is high enough to give real richness in coffee or a sauce, but too low to whip the way heavy cream can, whether fresh or thawed. Frozen for about 4 months, it separates on thawing and needs a thorough shake before use, and it's better suited to cooking than pouring visibly into a cup of coffee once thawed. It's also more prone to curdling on contact with very hot coffee or an acidic ingredient than heavy cream is, a heat-and-acid reaction distinct from actual spoilage, which shows up instead as a sour smell developing in the carton itself over time.

Because half-and-half is really just an already-blended mix of milk and cream, a carton nearing its date can sometimes be replaced entirely rather than frozen — whisking together equal parts whole milk and heavy cream makes a fresh batch on the spot, in exactly the quantity needed, sidestepping the freezing question altogether. For an opened carton with more left than will get used soon, portioning it into small covered containers or an ice cube tray before freezing avoids thawing the whole thing just to add a splash to one recipe. Frozen half-and-half tends to separate more dramatically than heavy cream does once thawed, since its lower fat content gives it less structure to hold onto through the freeze-thaw cycle.
