I found the link again this week and decided I wanted to have a go at that type of biscuit. Unfortunately, Amazon UK didn't have the kit and the postage from the German site was a bit off-putting so I thought I might have to give up the idea.
But then I wondered if it would work with a child's printing kit - obviously one that hadn't been used with ink. So, on to Amazon UK again and ordered myself this kit.
I tried it out this afternoon with these words:
This is how the biscuits looked before I baked them.
And how they looked after they came out of the oven -
I'm not disheartened though. I'll just try again with a recipe where the biscuits are rolled out and cut rather than rolled up in a sausage shape and cut with a knife.
And, even though it's not clear the biscuits say "mine", "eat me" and "yummy" - they are, I will eat them and they are yummy! :oD
Thanks, Anna, for the idea! :o)
