Which taste does your tongue detect most strongly: sweet, sour, salty, or bitter? You blindfold participants and give them four samples one at a time. Each person tastes sugar, salt, lime juice, and bitter chocolate. After each sample, they rinse their mouth. Then they report which taste felt the most intense. You record each person's answer and compare the totals. Most people in this experiment identified bitter chocolate as the strongest taste. The results show that the tongue may be more sensitive to bitter flavors than to sweet, salty, or sour ones.
