Well, after talking to my local store who deals in these things, they are looking into when it will be available in March. I will then go into town and buy real french flour baguettes from our Swiss patisserie, lurpak salted butter, and a jar of Marmite X.O.
This may be one of the high points of this year - who knows how good it's going to be.
For afficionados , try regular Marmite with romaine lettuce, similar baguette and lurpak butter.
There is no going back.
