A few days ago, we received a packet and amongst the goodies that we discovered, there was this delicious speciality...I want you to make your brain work and even hurt if that's needed! So, my question is: what is it (not the tree) and which region does it come from ?
Here is a clue: it is a Swiss speciality, it keeps well and it isn't necessarily eaten only on the occasion of Christmas or the New Year...
For the few Swiss people who already know, please don't give any kind of answer. Thanks!!!
