-Move out of my, way, Peter, I want to make a cake.
+ How do you make a cake, Mum?
- Well, listen and I’ll tell you.
First I mix the fat and the sugar there, do you see?
+ Yes.
-Then I add the eggs, one by one, with a little flour, and beat them into the mixture.
+ What cake are you making, mum?
- a chocolate cake.
+ What's the salt for, Mum?
- What salt? I don't put salt in a cake.
+ You did, you know. Perhaps you thought it was sugar.
- What?! Oh-, good gracious, I've put salt in instead of sugar! The cake is spoilt.
