Wash your hands and grate small portions of each food. Wash the grater after each use. Place 1/4 teaspoon of apple onto a spoon. Wash the 1/4 teaspoon and do the same with the other three foods. Arrange the spoons on a plate and cover them with a paper towel.
Blindfold a friend and lead him or her into the kitchen. Have your friend pinch his or her nose tightly and taste a spoonful of food. The samples should be rolled on the tongue, not chewed. Wait a minute or two, then ask your friend to identify the food. Write down the results. Your friend should rinse with water and repeat the procedure for each food.
What foods did your friend identify correctly? What foods were easier to identify? What role does smell play in identifying foods? We would like to know your findings. Click here for the form you can e-mail us.
