Why is it customary to eat dairy foods on Chanukah?

Eating dairy foods reminds us of the miracles performed through Yehudit, daughter of Yochanan the High Priest. After serving the Syrian General Holefernes salty cheese, she plied him with wine. when we was in a drunken stupor she killed him, smuggled his head out of the enemy camp and into the city where it was hung on the wall. When the Syrian army saw this they fled.
