I know that fresh ground wasabi is much better than the reconstituted paste. At the same time, the paste is much cheaper and generally more available.
Here's a tip from Just Hungry, a Japanese food blog. Just Hungry swears by the trick, which he learned from his step-father (who got it from a sushi chef and who lives in Japan).
First, mix in just enough water to make a thick paste. Do this in a small bowl. Once the wasabi has been mixed to a thick paste, invert the bowl onto a plate and allow it to sit for 10 to 30 minutes. For no rational reason, it's supposed to have far greater flavor when prepared this way. I haven't had a chance to try this, but I will. If you've tried it or have any other wasabi tips, feel free to share in the comments.
