When you’re making ramen at home, you can use homemade, fresh store-bought, or even dried noodles. For those inclined to make everything from scratch. But remember that even ramen shops in Japan buy their noodles. It’s not cheating — homemade ramen with purchased noodles is still homemade ramen.

Matching the right noodles with the right soup is important. In general, thicker soups tend to go well with thicker noodles, and lighter soups with thin noodles. Regardless of the soup, ramen noodles are best served al dente.

One serving of fresh noodles is around 5 ounces. One serving of dried noodles is around 4 ounces. At ramen shops in Japan, many people spend a little more to get a bowl of omori noodles, usually an 8-ounce serving or more. Occasionally, shops will serve a whole pound of noodles — something you should attempt to eat at your own risk!

This is your basic ramen-noodle recipe. These are also sometimes called chukamen, or Chinese-style noodles. The higher gluten in bread flour will result in ramen with a chewier bite. These noodles should be cooked and eaten the day after you make them. By letting the noodles rest, the gluten has more time to bond, and your noodles will have a better bite. If you want the noodles to last longer, one trick used by noodle makers is to add a teaspoon of sake to the dough. This will help preserve the noodles.

  • 1 teaspoon salt
  • 3/4 cup kansui water (see below)
  • 1 1/10 pounds (about 4 cups) bread flour
  • Cornstarch, for dusting


  1. Dissolve the salt in the kansui water.
  2. Put the flour in a large ceramic or stainless steel bowl, and add the salted water little by little, mixing with your fingers. Knead the flour in the bowl until it becomes yellowish. (This
  3. color change is due to the chemical reaction of the kansui and the flour.)
  4. Form the dough into a ball. Using your pasta machine’s thickest setting, run the dough through twice, dusting with cornstarch each time.
  5. Reduce the thickness a bit and run the dough through again. As the sheet of pasta gets longer, cut the sheet into strips about 1 foot long.
  6. Repeat at thinner and thinner settings. Go down to the second-thinnest setting.
  7. Attach the cutter and run the pasta sheet through to make noodles.
  8. Dust the noodles with cornstarch and portion into little bundles of about 5 ounces each. Leave in a cool, dry place for a day before cooking.

How to Make Kansui Water

To make kansui water, dissolve 1/3 cup of liquid kansui in 4 cups of water. So if a recipe calls for 3/4 cup kansui water, that means 3/4 cup of the solution you make by dissolving 1/3 cup of liquid kansui in 4 cups of water.

You can find liquid kansui on Amazon. Search for “lye water,” and then choose the product that is also called “Potassium Carbonate & Sodium Bi-Carbonate Solution” and has some Chinese characters on the label.

You can also make your own kansui water using baking soda. Baking soda has similar chemical qualities to kansui, although it needs a bit of preparation:

  1. Spread a layer of baking soda on a flat baking sheet and bake at 275 degrees Fahrenheit for 1 hour. Let cool.
  2. In a large saucepan, dissolve 1/3 cup of this baked baking soda in 1 quart of water and bring to a boil.
  3. Let it cool, then top up the water to get back to 1 quart (to compensate for evaporation).

This solution can be used, undiluted, in place of regular kansui water.
