There is so much to say about the combination of salt and chocolate that I will just stare, paralyzed, at the computer screen for three hours of insect brain-deadness… Salt and dark chocolate, salt and milk chocolate, salted chocolate, chocolated salt (I actually do have both).
But as with everything in life, the devil is in the detail. Salted 80% dark Italian blended chocolate (Salinae bar by Antica Dolceria Bonajuto) has nothing to do with 80% dark Italian Ecuadorian chocolate a chocolate (Blacksal by Domori), which in turn has virtually nothing in common with a 74% dark Italian blended chocolate served up side by side with Trapani and Cervia sea salts (Cioccolato Fondente al Sale di Cervia by Cioccolato di BruCo).
The power of salt to coax out, elucidate, and expand on the flavor of food does not stop with the savory. Actually, the idea that sweet and savory are somehow opposite is strange, and actually at odds with our natural affinity for diversity and complexity in food. Eat Ethiopian and you will find your fingers plunged in sugar on lamb with tamarind; eat dim sum and half the time you are eating donuts and pork. My grandpa was in love with apple pie with cheddar cheese. At any rate, chocolate is not even a sweet until after it is sweetened, and that can be done with much more deftness than is common.
