Q&A: What’s the Purpose of Salt in Making Chocolate Bars?

Here's a question I recently received from a reader, "What's the Purpose of Salt in Making Chocolate Bars?"

Answer

Strange but wonderful things happen from a sensory perspective when small amounts of salt are added to chocolate.

First, and perhaps counter-intuitively, it makes the chocolate taste sweeter, not saltier.

Next, salt masks bitterness, so the chocolate tastes richer.

Your tongue’s taste receptors are responsible for these phenomena... In the presence of salt, the tongue is more sensitive to sweet, tricking your brain to believe the chocolate is sweeter when no additional sugar is added.

Pretty cool, huh?
