I'm doing an activity to show the kids where the four kinds of taste buds are on their tongue. I am having a hard time coming up with bitter foods to have them try. The only ones I've thought of are baking chocolate and lemon peel. Does anyone have any other suggestions?
Unsweetened baking chocolate is the best for a bitter taste. Make sure you warn the children in advance that it is not like the chocolate they are used to tasting. I gave my children very small pieces one year, but it didn't quite agree with one of them, if you know what I mean. (We had to call for a clean up after the bitter taste test.)
Sour is not the same as bitter.
Sour would be things like lemon juice, ascorbic acid, sour candies. Bitter on the other hand would be baking (unsweetened chocolate) angostura bitters, or citrus peel with the white pith.
. . . that a person with no sense of smell can only taste those four tastes? For example, they can taste that something is sweet but cannot tell what it is unless texture gives a clue. You can check this out by holding your nose and eating something. I guess the test would be more effective if someone offered you a taste of one flavor of pudding, ice cream, popsicle, etc. without your seeing the color or appearance of it.
