Salt in coffee may sound like utter madness, but apparently it’s a thing now.
Seriously, it’s not just an unfortunate morning accident that happens when your eyes are too blurry to work out what’s salt and what’s sugar.
People are deliberately putting it into their coffee instead of sugar in an attempt to counteract bitterness.
A study in Nature showed that sodium ions suppress bitterness and enhance flavour.
And you just so happen to get sodium ions floating around when you add salt to an aqueous solution, like coffee.
