Custard Creams are good from just about anyone, and are one of those classic biscuits that the big supermarkets do very well as their own brand.
Its baroque embossing harks back to an earlier time where the Custard Cream was no doubt a sophisticated biscuit, not the old faithful its become today.
However stick a few on a plate at any informal biscuit eating event such as a seminar, or dare I say it, coffee morning, and watch them disappear.
