Vanilla ice cream is a churned frozen dairy food, flavored with vanilla, made from an aerated mix of milkfat, milk solids and sweeteners.
Cold and dense on the tongue, melting to a thick, creamy sweetness carried by a rounded vanilla aroma.
Bartenders scoop it into the blender as a bulk base, where it supplies chill, rich body and sweetness at once and melts into a viscous dairy liquid; a smaller amount enriches a drink as a creamy accent rather than a garnish.
As a small enriching accent it can be approximated with heavy or double cream, which matches the high dairy fat, rich body and pale colour — but the frozen aerated texture and chill are lost, and both the sweetness and the vanilla aroma must be added back separately since plain cream carries neither. As the bulk base of a blended drink it is essentially not swappable without rebuilding chill, body and sweetness together.
Frozen custard
Frozen custard is required to contain at least 1.4 percent egg yolk solids, whereas ice cream (except frozen custard) contains less than 1.4 percent; the two share the same milkfat and milk-solids standard but differ on egg yolk content.
Under the US standard of identity, ice cream must contain at least 10 percent milkfat and at least 20 percent total milk solids by weight, with lower allowances (8 and 16 percent) permitted on the flavor-free remainder when a bulky flavor is used. Except for frozen custard, it holds less than 1.4 percent egg yolk solids; vanilla is added as a flavoring ingredient to the sweetened, aerated mix.
Keep frozen below freezing; it melts to a sweet dairy liquid once softened and should not be refrozen after thawing.
