Как сделать
Hello, my dear. - cried the Vinegar witch. Welcome to my castle. Why have you come here?
- I'm looking for some magic mustard seeds. - said Sarah. They say somebody has stolen them. But some people say you have them. Is that true?
- Perhaps the people who say that are right. - said the witch and showed Sarah three boxes.
The magic seeds are in one of these boxes. - said the witch.
- Which one? - asked Sarah.
- We aren't going to tell her that, are we, Midnight? - said the witch. You must guess.
Sarah opened the smallest box and found a bag of mustard seeds inside.
- Excellent. - said the witch with an ugly smile.
Sarah ran out of the witch's castle in a great hurry. At last she got to palace.
- Here you are. - she said to the doctor. I have found them.
Now the prince pepper will feel better.
- Well done. - cried the doctor and queen Salt together.
The queen went to the kitchen. She came back a few minutes later with a sandwich on a silver plate. It was a ham sandwich with magic mustard in it. The prince began to eat. Suddenly his face went red. And he started to cry.
- What has happened? - cried his mother.
- Nothing. - answered the prince. But the mustard is so hot. I have never eaten such hot mustard. It is burning inside me.
Sarah said - That is why the witch smiled so nastily. Sara thought. But she didn't know I had magic water.
She gave the prince a silver cup with magic water and the prince felt fine.
- Why don't we have a party with everybody's favourite food? - he said and invited a lot of guests to Pepperpot Palace.
