[UPDATED] The pre-packed custard now comes with a new “convenient” supposedly “tamper-proof” seal. Instead of having to rip off the inner seal, under the cap, the inner seal is automatically broken when you unscrew the outer cap.
All very convenient, perhaps, but my first reaction was that this defeated the whole purpose of the seal. What’s the point of having a tamper-proof seal if you can’t tell whether it’s been tampered with?
It’s now been pointed out to me that it is possible to tell if the cap has been tampered with. There are 3 small plastic connections, which are broken when the cap is rotated. All very subtle, it seems to me, but perhaps clear enough if you know what to look for.
