I have read that some people use gold seal found in the kitchen paper section of the supermarket.... I can't remmeber and a google doesn't bring it up what it is used for in the kitchen....
I know it can be purchased in the USA.
Hopefully someone on here can be a bit more helpful. I am trying to remember the brand name.
It was a New Zealand person purchasing it ....I think it was on this site.
It was press and seal not gold seal.
