Expiry date of custard powder? I bought a pack of 'Custard Power' around 4 year ago. I placed the pack in my store room and completely forgot about it until now. The packet was 100% unopened until yesterday, when I found it. I cannot seem to find an expiry date, but the powder still seems fine.

Can I use it, or should I throw it and get fresh?
Products like custard powder don't come with a use by date, instead they have "best before".

To be honest I see no reason why if kept dry custard powder would ever be inedible. Especially if it is just the corn flour and colour mix.
