Hey...just this evening I had fair success with my first shot at Udon. I did chicken tempura on the side and made the Udon in a dashi base with shiitake mushrooms, broccoli, carrot, baby corn and lotus. I topped it off with an egg, just like the above.
As an aside...the best use of additional cracked egg I ever had was on a pizza I had last summer in Italy. It was a mixed meat pie and just before it finished the cook pulled it from the oven, cracked the egg in the center, and put it back in for few seconds. Just enough to cook the white and set the yolk. When served the yolk was still soft and running. Yummy.
