What are these weird things in my cupboard?

[CloseEncountersOfTheTurdKind]

I found loads of these things in my understairs cupboard. They are reddish brown and about the size of sesame seeds. Any ideas what they are?

I can’t see a picture?

Sorry, for some reason it posted the tread twice! There is a picture on the other thread, and it turned out they were cress seeds!
