Udon noodles in a curry broth is a typical combination at udon noodle bars. This mushroom curry udon recipe gives that tasty broth a whole lot more character with the addition of both fresh and dried mushrooms.
The curry powder used to make the curry sauce is quite important. While you could use a South Asian style curry powder, I think one of the reasons this mushroom curry broth worked so well was the Japanese style curry. Originating from the familiar South Asian roots, Japanese style curry has evolved in a very different direction. As with how South Asian style curry made its way to Vietnam, the story of how curry made its way to Japan is similarly intriguing. You can find links to these stories in the Food Stories section.
I used S&B Oriental Curry Powder, one of the most famous and widely available Japanese curry brands. You could also use a curry sauce mix – S&B and Vermont being the most popular brands in Japan. Or make your own from the individual spices! Maki at JustHungry.com also does a good analysis of what spices are actually in Japanese curry.
Using dried mushrooms brings an earthy complexity and depth of flavour that fresh mushrooms can’t deliver. The Science of Cooking site has a good piece on why dried shitake mushrooms can taste better than fresh. For this mushroom curry udon dish, I used a dried forest mushroom mix and some dried shiitake mushrooms.
As a vegetarian dish, the dashi used will need to be vegetarian. That would mean dashi made with kombu and dried shiitake mushrooms. Should you not be strictly vegetarian, then use dashi made with kombu and katsuobushi (dried bonito shavings). The smoky flavour of the katsuobushi adds a distinct extra dimension to this mushroom curry broth.
I purposefully constructed this recipe so that the base was a curry paste. There were two reasons for this. Firstly, adding tsuyu to the curry paste to create the mushroom curry broth helps create layers of flavour. Secondly, I like making more curry paste than I need and freezing it in 1/3 cup quantities. When defrosted and heated with 2/3 cup of tsuyu, you get a very delicious and nearly instant udon meal.
You can simplify things a little by buying prepared tsuyu, called men-tsuyu. For most preparations, use 1 part men-tsuyu to 3 or 4 parts water. And then, of course, using men-tsuyu for your subsequent instant udon curry meals makes a lot of sense.
