Weird English from Europe

You'd think that Europe wouldn't exhibit any bad English since a lot of people have studied it, and they've been interacting with England, Ireland, and Scotland for years, but I spotted some strange English on the label of this fruit spread when I was in a German store yesterday. It said: "For a superb taste mix fruit on top down into jar."

What does that mean? I understand the first few words, but then the meaning breaks down as the sentence continues. You'd think the French company that puts this product out would find *someone* who can verify that the English is correct. Puzzling, indeed.

Update: upon reading it again a few times, I think they mean that you should mix in the fruit that is on the top.
