Legendz has a great list for this achievement, make sure to copy and paste it to notepad or write it down somehow (adding pie to the list) so you can check it off or delete what you already did. I will add a few more things to help you get this achievement.

1st) if you want to know if your ice pops or vegatables are melted/thawed you can drop them on the ground and it will say they are when you stand on top of them. This is the same with Rotten Pizza because Rotten Pizza and uncooked pizza almost looks the same.

2nd) Here is a complete list of all mixes for mixed drinks, if you have 1 food item you can go directly to it and it will tell you what you can mix to make what drink. This Mix guide was done by Yukichigai on Gamefaqs:
