Allison,
Most of the umeboshi is produced in Japan and much comes to the United States but I'd be willing to bet you that many folks in Canada get umeboshi, and not just by bringing it back with them after visiting the States.
My guess is that you want umeboshi soon and not next year after you've grown the plums and apricots, harvesting them and curing them, before pickling them!
By the way Jon and Jan Belleme's book
Japanese Foods That Heal: Using Traditional Ingredients to Promote Health, Longevity & Well-being describes in detail how umeboshi are made traditionally in Japan!
Of course if you have the fruit, now and you want to get started on making your umeboshi, here is
a recipe I found typing "making umeboshi plums" in Google.
Have you contacted all the
health foods outlets in Calgary about whether they have Umebosi or not and/or if they can order it?
Contact:
Arirang Oriental Food Store
1324 10 Ave Sw # 30
Calgary AB, T3C 0J2
Phone: 403-228-0980
Fax: 403-228-9977
and see if they either have umeboshi or can order it for you.
Thank you, very much.
