This is a chilled udon dish topped with a thick mentaiko and Japanese yam sauce. The rich parmesan cheese makes this amazing!
I wondered if a thick mentaiko sauce would taste good with chilled udon, so I made this recipe.
It also tastes good if you use spicy mustard mentaiko. If it's too much work to grind, you can just combine everything as-is and it will still be plenty delicious.
Enjoy Japanese food around the world.
