Why soak oranges overnight for marmalade?

[zoeyy]

I've heard that soaking oranges overnight is a crucial step before making marmalade. Can anyone explain why this is necessary? Is it really that important, or can I skip it without ruining the marmalade? I'd love to hear your experiences and tips on this!
