It's like ryvita as it's promoted as a bran crispbread. It's more like a hard crispbread-shaped block of branflake but unsweetened lol No good to eat on it's own but useful in recipes as you say - I like the scanbran christmas pud
You can get them at meetings or in holland and barrett - it's about £1.09 for a pack of ten. They prolly do them in some other healthfood shops too I'd imagine.
