Though they are not green, pumpkins are closely related to cucumbers. They are all part of one big family that includes such fruits as melons, gherkins and courgettes.
They come in all sorts of wonderful colours; some of them are edible, others aren't. What they all have in common is their structure: a thick rind with soft flesh inside.
Just like their siblings, pumpkins come from the tropics of North and South America. They contain big flat seeds that are rich in oil. You can toast the seeds and serve them up as tasty finger food. The young stems and the flowers are also edible.
