I understand that if there is not a kosher mark on something, it is not officially kosher.
I have not noticed a kosher mark on Toblerone, but I have not looked for one, either, as I am not Jewish, and therefore do not actually care. I suspect that there was some sort of joke in circulation about the kosherness of Toblerone going on when this video was made.
Toblerone is almonds, sugar and milk/cream, I think. It is quite tasty.
