Amarettini. An Italian sweet made from apricot stone flour, icing sugar and almond flour. It has magical addictive properties but is hard to get as the little balls loose their flavour and structure after a few days or less. It has to be fresh and the industry packs them into tiny plastic bags filled with nitrogen gas to prolong the flavour. However that trick helps only a bit. I ate a bag with some dozens until I was fed up. Since then I limit myself to less than ten of them.
