Why desserts need a pinch of salt

A little salt makes sweet foods taste rounder and sweeter. One reason: salt turns down the bitter notes in chocolate and caramel that hold sweetness back. Add too much and the dessert just tastes salty.
Salt mixed in or sprinkled on
Salt stirred into batter spreads evenly and lifts the whole dessert. Flaky salt on top works differently: a bite that lands on a crystal tastes sharply salty against the sweetness around it. Same salt, two jobs.

Questions from the interactive lesson, with the answer and the why.
Why do most brownie recipes call for a pinch of salt?
It reduces bitterness so the sweetness stands out. Salt dampens the bitter edge of cocoa, so the sweet and chocolate notes come forward.
True or false: The more salt you add to a dessert, the sweeter it tastes.
False. A small pinch helps. A heavy dose just makes the dessert taste salty.
What went wrong? You leave salt out of a caramel sauce because it's a dessert. The sauce tastes flat.
Salt would have reduced the burnt-sugar bitterness. A small pinch quiets the bitter edge so the sweetness reads clearly.
Fill the blank: A small pinch of salt makes a dessert taste ___, while a heavy dose makes it taste salty.
A small pinch of salt makes a dessert taste sweeter, while a heavy dose makes it taste salty. The pinch quiets bitter notes, so sweetness reads stronger.
True or false: The same brownie batter can taste sweeter with a pinch of salt than without it.
True. Salt turns down bitter notes in the batter, so the same recipe can taste sweeter with a pinch.
