miltonkeynesmum,
You ever wonder, who it is that you are talking to?
Maybe I should shut up, which would be one kind of mum, but I believe the kind of mum that you are, is someone's mommy (or two someones' mommies), for that matter!).
Milton Keynes is a place very few of us has been to and at first glance, I said, "who does she think she is? She can't possibly be old enough to be Milton Keynes (read 'British economist John Maynard Keynes['s]') mother!" (ha ha ha! ;-)
Today, I've found out that Milton Keynes is someplace in the middle of England, somewhat west of Cambridge, somewhat north of London http://www.mapblast.com/UK/(vkwnpy55ep2wrgy10gl0no55)/map.aspx?L=USA&C=52.02301%2c-0.74368&A=215.00000&P=%7C990629%7C&TI=Milton+Keynes%2c+England%2c+United+Kingdom .
You better hope that not very many mommies from Milton Keynes comes on this list or you might have to give us a new name ;-) .
About that expression, "Cripes!", we don't hear it much, stateside, but here's a blog
http://suzette.typepad.com/suzette/ that uses the word as part of it's title and you might enjoy reading it, as well.
Do you know how to search for things on the World Wide Web?
Here are three bunches of sites that I found on Google
http://www.google.com/ , employing the words organic, tortillas, Milton Keynes, and UK in several combinations:

http://www.google.com/search?q=organ...UTF-8&oe=UTF-8
http://www.google.com/search?q=Milto...UTF-8&oe=UTF-8
Regarding those organic tortillas in Milton Keynes or thereabouts, my guess is that if you can't find any organic tortillas nearby then you might need to find some Milton Keynes daddies, single blokes or lassies to form a macrobiotic dinner club with you, and start producing them together!.
Otherwise, you will have to do all of that organic masa harina making, yourself!
Good luck!
Thank you, very much.
