La Perruche irregular sugar lumps are a real treat!  And this is coming from someone who generally speaking, doesn't care for anything sweet.  Maybe it's in my head (after all; refined sugar is refined sugar, right?...) but I swear this tastes different than dominoes sugar.  It's lighter on the tongue and not so cloyingly sweet.  I just popped one in my mouth earlier today to enjoy - what a delight!
