JACKSON: For some time now I’ve been toying with cross-pollination. Finally I’ve got it. I figured out a way to cross a raspberry with a cumquat.
A cumquat is a small cold-hardy citrus fruit native to south Asia and the Asia-Pacific. They were introduced to Europe and North America from China in the 19th century.
In reality, it is not possible to cross a cumquat with a raspberry. It’s clearly just a joke by the scriptwriter, but if you were determined to make this a semi-believable situation, yellow raspberries do exist, and Jackson might have bred one with an especially sharp, citrus-y flavour, making him over-excitedly believe that he had somehow crossed a raspberry with a cumquat.
