Mike's Premium Melogold Grapefruit jelly made from fresh grapefruits in Northern California.  Taste is not-too-tart, and just sweet enough for grapefruit lovers and citrus/marmalade lovers alike!
 
"Melogold is one of the pummelo hybrids that resulted from the UC Riverside breeding experiments.  It is a cross between Siamese Sweet Pummelo and a white grapefruit. Pummelo lovers who dislike grapefruit should not dismiss Melogold because of its grapefruit parent; Melogold is much more like a pummelo than a grapefruit in both size and flavor. Melogold is mild, sweet, and juicy. In the taste test Melogold scored between “very good” and “excellent, outstanding.”
