     What do you want to be when you grow up? A teacher? A

doctor? How about an ice cream taster?

       Yes, there really is a job where you can get paid to taste ice

cream. Just ask John Harrison, an " Official Taste Tester" for the

past 21 years. Testing helps manufacturers to be sure of a product's

quality. During his career Harrison has been responsible for appro-

ving large quantities of sweet ice cream--as well as for developing

over 75 flavors(味道).

       Some people think that it would be easy to do this job;after all,

you just have to like ice cream,right? No-there's more to the job

than that,says Harrison,who has a degree in chemistry. He points out

that a dairy or food-science degree would be very useful to someone

wanting a career in this "cool"field.

       In a typical morning on the job, Harrison tastes and assesses

60 ice cream samples. He lets the ice cream warm up to about

12°F. Harrison explains, " You get more flavor from warmer ice

cream, which is why some kids like to stir it, creating ice-cream

soup. "

       While the ice cream warms up, Harrison looks over the samples

and grades each one on its appearance. "Tasting begins with

the eyes," he explains. He checks to see if the ice cream is attractive

and asks himself, "Does the product have the colour expected

from that flavor?" Next it's time to taste!

     Continuing to think up new ideas, try out new flavors and test

samples from so many kinds of ice cream each day keeps Harrison

busy but happy-working at one cool job.
