Sometimes a random series of events occur that result in a happy accident.
I usually have a handful of nuts as my morning tea. Generally I'm careful to select raw, or at least unsalted nuts but a super sale price led to an impluse buy of some delicious salted cashews. Because I'm useless at stopping eating nuts if I have them straight from the packet I always put them in a little dish for portion control.
My other usual snack is some form of chocolate mid-afternoon. At the moment I'm completely in love with these freeze dried, chocolate covered blueberries. Anyway, again I could easily eat a whole packet in one sitting, so I poured out a few into the dish which had previously held my cashews - and in which remained remnants of the salt - resulting in salted chocolate blueberries.
We all know salt is a flavour enhancer but I often forget how it can enhance sweets. All I can say is salted chocolate blueberries are incredibly addictive. Never fear I'm not going to suddenly end up with a salt addiction but it did remind me that I should experiment a bit more with the interesting ways that you can enhance flavours.
