@Miyono-chan LOL I read the Spanish version of the tale 🤣
The king asked how much his 3 daughter loved him and the oldest said: "i love you as much as bread" which pleased the king. The second daughter answered "I love you as much as wine" and the king was again very happy with it. And lastly, the youngest replied "I love you as much as salt" which did not convince the king and as she refused to elaborate her statement, the angered king kicked her out. She married a influential person and one day received the king for a meal. She herself prepared everything and made sure there was plenty of bread and wine but she did not put any salt to anything. As the king was eating and everything was bland because of the lack of salt he said: "I would be fine without bread or wine as long as I have salt" and then the daughter appears asking: "Really? Do you perhaps remember a daughter who once said she loved you as much as salt?"
If context is necessary, bread and wine are imprescindible accompaniments for a Spanish meal that's why the king was pleased by their answers.
Also, I recently found out in literature class that Shakespeare's
King Lear begin with a similar premise. And for some reason my teacher never heard of the tale. Weird.
