Isn´t impossible to conjure food?

1st possibility: It is possible to conjure liquids, but not food.

2nd possibility: Ollivander didn´t actually conjure it, but summoned it. --Rodolphus 13:23, September 16, 2009 (UTC)

I think the 1st possiblity is more likely. After all, both Aguamenti and this spell conjure liquids. --  Seth Cooper  owl post! 15:02, September 16, 2009 (UTC)
Molly Weasley also made "a creamy sauce" pour from her wand tip in GoF (p.59) - Nick O'Demus 16:20, September 16, 2009 (UTC)
