reading sadler's book on the tea ceremony ( cha-no-yu) and am struck by a story on the tea master rikyu:

hiki hyaku-o once invited rikyu to tea and served

water-melon with sugar over it. rikyu ate only that part that had no sugar on it and when he got home again said with a smile to his pupils:

"hyaku-o does not understand how to entertain people.He gave me watermelon with sugar over it. water-melon has its own natural taste. It does not need any other flavour".
