Now, I have yet to purchase any, so I don't know what it tastes like but I have found some soy free (and as it happens some are also vegan, so that's useful for some of my occasional visitors) fairtrade chocolate.... HURRAH!
It's available here ... just hoping they don't sue me for adding the link as a scary message popped up on the website when I tried to open in a new tab with a right mouse click!
I'm a happy soy-free chocaholic!
