half & half
Also known as: half and half
A dairy product that's roughly half whole milk, half cream, landing in richness between the two -- pourable like milk but noticeably richer, with just enough fat to round out coffee or lighten a cream sauce without the heaviness of straight cream. Common in coffee, light cream soups, and sauces where full cream would be too heavy.
Buying guidance
Check the fat percentage on the carton if precision matters -- "half-and-half" isn't strictly fixed at one fat level across brands, and its relatively low fat means it can curdle in a hot or acidic sauce where heavy cream would stay smooth. Buy close to the sell-by date; it can turn sour faster than plain milk.
Substitutions
- Heavy cream diluted with an equal amount of milk -- close to the same fat level and body; mix just before using.
- Whole milk -- thinner and less rich, but fine in coffee or wherever the extra fat isn't needed for stability.
- Heavy cream, undiluted -- richer and more heat-stable than half-and-half, useful if a sauce needs more resistance to curdling.
Tips & common mistakes
Its lower fat content makes it curdle more readily than heavier cream in a hot or acidic pot -- stir a spoonful of the hot liquid into the half-and-half first to warm it gradually before pouring it all in, rather than adding it cold straight into a simmering pan.
Storage
It doesn't freeze well: the milk and cream separate as it thaws, leaving a grainy, broken texture that won't recombine no matter how much you whisk it.
