A pumellow is a hybrid citrus fruit that results from crossing a pomelo (Citrus maxima) and a grapefruit (Citrus × paradisi). It typically has a sweet and tangy flavor, combining the characteristics of both parent fruits. The pumellow can vary in size and color, often resembling a large grapefruit, and is known for its juicy flesh and thick rind. It is less common than its parent fruits but can be found in some markets.
