Strega Nona by Tomie dePaola, 1975.

Strega Nona is a witch who lives in a small town and uses her magic to help people in various ways, everything from small cures or love potions.  However, she runs into problems when she hires Big Anthony to help her around her house.  Big Anthony is helpful, but he doesn’t always pay attention or follow orders.

Strega Nona has a magical pot that makes pasta.  To get it to make a never-ending pot full of pasta, she recites a certain rhyme.  To get it to stop making pasta, she recites a different rhyme and blows three kisses to it.

Big Anthony is forbidden to use the pasta pot himself, but he can’t resist telling people in town about it.  At first, no one believes him because it sounds so strange.  Everything thinks he’s just making it up.  Big Anthony is offended that no one believes him, so one day, while Strega Nona is gone, he sets out to prove to everyone that this magical pot exists.

Big Anthony knows the rhyme to get the pot to start making pasta, and he uses it to make pasta for everyone in town so they will know that he was telling the truth.  Unfortunately, he doesn’t really know how to get it to stop because he didn’t know that Strega Nona blows kisses to the pot.  With the pot now sending a massive river of pasta through the town, what can Big Anthony do?
