Blue Yorkie, melted in a pan and poured over ice cream and left to re-harden. Mmmmmmmmmmmm, it ever so slightly sweetens the chocolate. But remember, it's not for girls !
id say flake or aero they are the best. flake because it is sooo flaky and satisfying
and aero because the air bubbles in the middle make it so light and they melt in youre mouth!
