Thanks case but it is in the shops here, just that shops are a little scarce round my way.
Thanks xob -all that I ever needed to know!
And Pete - when I googled snickerdoodle without cream of tartar I was amazed to see that it was a suggested search and there are lengthy discussions on t'internet which say what you say!
I'll buy some.
In the meanwhile, I'm baking Hot Cross Buns (a little late, should'a been yesterday!).
