Cake or soup?

Mr. Anatole has invited over Miss Blanche for tea, but he’s having trouble with his cake recipe. "Why, it’s so easy!, says the pig, who comes to help him. "Just add potatoes, and you’ll have a potaterrific cake!" Then the rabbit says: "Don't want your cake to taste like poo? Better add a carrot or two!" And then everyone adds their favourite ingredients to the cake… which makes for a rather surprising result!
