http://www.onthechoppingboard.com/p/cold-japanese-noodles-remen.html Hiyashi-chuka is basically a dish of cold noodles with selected ingredients mixed together with a sauce. There are no rules in what types of ingredients you want to accompany this dish. As you can see below, the one I had tonight included ham, egg, cucumber, tomato, corn, and avocado with cold Ramen. The method is basically boil your preferred noodles (Ramen, Udon, Soba, Somen, etc) and rinse it under cold water and leave to cool. Once the toppings are placed into the bowl, you can pour/scoop as much or as little sauce into the bowl and mix the noodles together. The sauce is the most important part of this dish, and the recipe for 2 types of popular sauces are here. Sesame based sauce: Soy Sauce - 4 table spoons Sugar - 5 tablespoons Vinegar - 4 tablespoons Chicken Stock - 8 tablespoons Sesame Oil - 2 tablespoons Sesame Sauce - 3 tablespoons Sesame seeds Method: Boil water and add chicken powder to create chicken stock (or you can buy premade stock) Add the hot stock and sesame sauce into a bowl and mix well. Add the rest of the ingredients and leave it to cool. Serve on top of cold noodles. Soy Based Sauce: Mirin - 100ml Vinegar - 100ml Soy Sauce - 8 tablespoons Sugar - 1 tablespoon Sesame Oil - 1 tablespoon Grated Ginger - 1/2 table spoon Lemon Juice - 1/2 tablespoon Method: Add all ingredients into a small pot and bring to the boil. Leave it to cool Just before serving, add the sesame oil, ginger and lemon juice Serve on top of cold noodles If you prefer to not have any toppings and just prefer a nice cold dipping sauce for Soba, Somen, or Udon follow the sauce recipe below. Cold Dipping Sauce Water - 400ml Konbu (Seaweed) - 5x5cm pieces Mirin - 70ml Soy Sauce - 70ml 1 packet of Dried Bonito Flakes (20g) Method: Put the water, Konbu and soy sauce into a pot and bring to the boil with LOW heat As soon as it boils, add Dried Bonito Flakes. Keep boiling for an additional 5 minutes. Leave to cool. For additional flavour, chop up some spring onion and grate some ginger into the sauce before dipping noodles.
