put it in miso soup!
i usually boil it in a separate pan with a tiny bit of water until it's a little cooked, then put in the soup. dd looooves cooked daikon, it becomes quite sweet when it's cooked.
a very traditional way of eating it is to grate it very fine and put it on grilled fish, it works particularly well on oilier fish like salmon.
i also love eating it plain and raw.
