Why not head over and have a look at what is going on.
Myself I have cleared out and defrosted a freezer and found some bits lurking in the backs of the shelves.
The idea of the challenge is to only use what you have either in your pantry or fridge or freezer.
If needs must you can purchase fresh milk and veggies.
This idea also uses up things that maybe you've bought thinking they would be a good idea but never gotten round to using.
I run a pantry store cupboard so the theory is that I should never have to "nip" to the village shop for a staple ingredient.
As items are used from my pantry I mark them onto my master shopping list, so that they are replaced on the next shop. The idea behind this is that I could if necessary (illness, weather, unforseen extra expense) use the items from the pantry and not have to worry; we live approx 10 miles from the nearest big supermarket.
