Some say they store almost indefinitely if dry & cool.
Delia says 4 weeks in fridge.
Suppliers say 7C or below till BBE date - which is not on the pack!!
Wonder how long they have been in commercial storage at what temperature?
Tim good point you don't know how they've been stored, transported or generally handled prior to you getting them !

I am sure they last for a lot longer than 4 weeks, certainly a few months. Most people have them in their lareder for a long while. If in doubt, put them in the freezer after opening the pack.
