Chances are good that you had these as a kid. Zotz are fruit-flavored, hard candy with a fizzzy center, and the fizz tickles your tongue. They come in six flavors: lemon, orange, grape, sour apple (my favorite) cherry and watermelon.
The actual name of the candy is “Zotz Fizz Power Candy”. I just discovered that they are made in Italy. Any time you see hard candy from Italy, buy it. Italians are great at candy making.
You can find these where penny candy is sold. They usually come in a string of four individually wrapped candies.
It’s nice to see that Zotz are still around.
