In a Japanese cooking book I’ve found the basic recipe for the soup e.g. used for noodle soups (ramen).
Ingredients:
6 cups dashi or chicken stock
1/2 cup light soy sauce
1/2 cup mirin
1/2 teaspoon salt
Monosodium glutamate
Preperation:
Heat the dashi or chicken stock and taste for seasoning. Add the mirin, soy sauce, salt and a dash of monosodium glutamate. Bring to the boil and taste again for seasoning, correcting if necessary. Simmer for ten minutes.
Dashi is bonito based fish stock often used in Japanese cooking. If you make your own miso soup with miso paste, it’s recommended to add some dashi.
Monosodium glutamate is better known as aji-no-moto in Japan. It’s got a very interesting story behind it that you can check on Wikipedia. You will also find out more about umami, the so called 5th taste that some people believe to be lots of nonesense.
Instead of dashi or chicken stock you can use any kind of soup stock, like beef. After I cooked bigger amounts of meat e.g. in the steam cooker, I often use the fresh stock/juice left over as the soup base in the next ramen.
There are three basic tastes of ramen: shouyu (soy sauce), shiyo (salt) and miso. I find this recipe to be close to shouyu ramen, even I don’t know if that’s true by definition. This was the only recipe I could find in that book. If you want to cook miso ramen, use dashinand miso paste, but no (or little) soy sauce or mirin. Also for shiyo ramen, use less dashi and soy sauce (a bit is nice for seasing) but you can add lots of salt so that it gets a really nice salty taste. Of course if you leave out soy sauce or dashi, add the same amount of water instead.
If you put it all together you get 7 cups of soup. This results in about 2 servings. I usually use about 3 1/2 or 4 cups of soup per serving, which results in a bit less than 500 ml.
This type of soup for ramen is called kakejiru. For some other noodles like soumen you use a more concentrated version called tsukejiru, in which you only dipp the noodles. The ingredients are as follows:
2 cups fashi or chicken stock
1/2 cup mirin
1/2 cup dark soy sauce
Monosodium glutamate
Mix all ingredients in a small saucepan and bring to the boil. Taste for seasoning, correct if necessary and cool before using.
For soumen, each person gets about 1/2 to 1 cup of tsukejiru.
