h2g2 The Hitchhiker's Guide to the Galaxy: Earth Edition

You may have noticed that if you buy a packet that says "Jammie Dodgers" on the outside, you get a packet of biscuits that are almost, but not quite, entirely unlike the biscuits described in this entry. The biscuit layers are made of shortbread and there's no cream, and so they manage to soak up all the moisture in your mouth - an altogether substandard biscuit experience.

The biscuits we're discussing are referred to on the back of family assortments as "Sandwich cream biscuits" or something like that, and it seems to be impossible to buy a packet of them, thus raising their status within the 'grab 'em quick before they all go' family of biscuits.
