Hmmm. How difficult would it be to pack some in a sealable container?
Fairly easy if it is a glass jar (I have many of those), a little more tricky if it is to be plastic as I'm less certain I can easily find one of those. Glass may fracture in transit, which is why I would prefer plastic, but if I can't find one of the latter it will have to be a glass jar (standard consumer-size Patak's jar).
I don't think I'd ever make a dent in 2.4kg!
I know the feeling !
Phil - I totally appreciate your help in sourcing this!
You're very welcome : CR0 is, after all, a place where we all try to help each other.
What I will do is weigh a standard Patak's jar, ready filled, use that the work out the postage, caculate what fraction of a 2,4kg tub will be needed to fill the jar, work out the cost of that, then let you know the total. You can then decide whether you want to go ahead, and if you do, I will order the tub and set things in train.
