Osumashi with Egg, Shiitake & Leek.

How to make Japanese osumashi soup with shiitake mushrooms egg and leek by kurumicooks easy tasty healthy Japanese Asian and Fusion food and cooking for your kitchen

I can't think of a more quintessential Japanese light healthy meal than a small bowl of "osumashi" clear soup and a bowl of rice, served in a lacquered bowl. Picture the scene - it's warm, rather muggy but you need some nourishment. So you slice some shiitake and leek, make up a consomme style dashi base and cook for a few minutes until the vegetables are softened. Stir in a raw egg for each serving (It will cook in the heat of the soup) and your dish is ready - nourishing, hydrating and easily digested. Pair your osumashi with a bowl of rice perhaps topped with some fermented pickles for some tangy, palate clearing flavour and there you have it - you'll rise from your table feeling sustained, hydrated and ready to take on the summer's warmth again. Of course, the contents of an osumashi are variable and to a great extent depend on what you have available. A classic osumashi should be made using a little fish or chicken but egg works equally well - rather than enriching the flavour of the consomme as chicken and fish would, the egg is there for nutrition only and let's the diner enjoy the taste of the osumashi accompanied by the subtle flavours of the shiitake and leek. I used dashi granules to make the consomme base but if you wanted something a little more refined in terms of flavour, you could use a "dashi bag" which I find provides a richer flavour. Making your own dashi from scratch is the most authentic solution and you can find some dashi recipes in the Soups and Stocks recipes section on my site but I appreciate that you might want something a little faster, so this time, I went with the fastest route by using dashi granules from a jar.
