Ladles are ideal for getting liquids out of deep containers.
I know this isn't quite what you're looking for, but is it close enough?

From a Google image search on "wood ladle"
Roy Underhill's "The Woodwright's Shop" show on PBS (he also has books) covers traditional woodwork. He might cover making spoons, but I haven't seen any details of which episode/book would be best.
HTH!
Cheers,
