Salt's Triple Trick
Why does salt make food taste different?

You sprinkle a little salt on your fries and suddenly they go from boring to delicious. What is salt actually doing in there? It's not just making things "salty" — it's performing three completely different magic tricks on your tongue at once.
Your tongue is covered in thousands of tiny taste buds, each one like a detective trying to figure out what just landed in your mouth. They send signals to your brain: "Sweet!" "Sour!" "Bitter!" But they don't all shout at the same volume. Some tastes are louder than others, and salt is the volume knob.
