Now you tell me! For 77 years I've been calling a tablespoon a soup spoon. I don't think I would want to use a tablespoon for dessert; that seems like overkill for rice pudding, flan or ice cream. For wonton soup or just Sechuan wontons in America those ceramic Asian style spoons are very handy. Wontons are the one thing that challenge my otherwise adept use of chopsticks. I can do it, but I like an assist.
For some ungodly reason most of my husband's siblings and parents used teaspoons for soup. That's just weird. And they are all big tall people with big mouths.
