A cherry tomato is a smaller garden variety of tomato. It is marketed at a premium to ordinary tomatoes, and is popular as a snack and in salads. Cherry tomatoes are generally considered to be similar but not identical to the wild precursor of the domestic tomato. They are often more sour than standard tomatoes. Cherry tomatoes range in size from a thumbtip up to the size of a golf ball, and can range from being spherical to slightly oblong in shape. The more oblong ones often share characteristics with plum tomatoes, and are known as grape tomatoes.
