Roll up tortillas loosely and fasten with a wooden toothpick to create a shell, form so hollow in centre (like a brandy snap) then fry a few at a time until they are golden brown.
Mix cinnamon and sugar.
Mix together ricotta and jam.
While shells are still warm roll in cinnamon sugar , holding one of the ends, dip in melted chocolate and roll in finely diced nut pieces.
Fill the cannolis with the ricotta jam mixture.
These are best filled with a pastry bag.
But a table knife, heaped with mixture and slid in will work.
