Raining and chilly out? How about a nice warm bowl of soup with handmade noodles?
Without a doubt, it will comfort you both in stomach and mind. The handmade noodles are very unique in texture and taste, nothing like what you get typically from the store. Try it!

If you are busy, you can purchase pre-made noodles from a Korean store. You can even make it without clams. See tips for details.

Optional Ingredients and Substitutions
Noodle: You can buy pre-made Kal-guk-soo (Korean style handmade noodle) from Korean stores if you don't have time to make it. You can use udon noodles instead but the texture and taste will be slightly different.
Claims: You can make it without clams. A good amount of anchovies and kelp will make a great broth.
Kelp: Dried Kelp is a great addition to the broth, but can be omitted.
Soy sauce for soup: if you don't have soy sauce for soup, add more salt instead.

Good to Know
You can also make this with other seafoods or chicken. If you are using chicken, be sure to include bones for rich broth. See how to make chicken broth here.

1. Dough

Mix 4 cups of flour, 1 cup of water, ½ teaspoon of salt and ½ teaspoon of vegetable oil. Knead until the dough becomes smooth and elastic (about 10-15 min). Wrap the dough in plastic wrap and let it rest in the refrigerator for at least 30 min to allow the gluten to relax.

2. Prepare short-neck clams

If you are using fresh live clams, place them in cold salt water (add 1 tbs of salt into 4 cups of water) and cover the bowl so the inside the bowl is dark. Leave it for a few hours and clams will open up and spit out sand. Wash in cold water twice and drain. If you are using frozen pre-washed clams, you can just add them in the soup later.
