Black beans are soaked enough in water like this. I washed it before going to bed and soaked it in cold water. When I wake up in the morning, it's swollen well.

Soaked black beans are taken out on the sieve like this. You can boil the water without throwing it away. At times like this, you have to wash the beans well and soak them.

Mix our wheat flour with a little bit of lotus leaf powder, green tea powder, or spinach juice and knead it in two colors. When I kneaded, I mixed a tablespoon of sunflower oil. Then it's good because the dough has elasticity.

Cover the dough with a plastic wrap pack and leave it in the refrigerator for about 30 minutes.That way, it's soft and chewy.

Now boil the beans. Add plenty of water and boil. That's how the soup acts as a broth. If there is less water, the kalguksu becomes stiff...

Peel a handful of roasted peanuts and grind them with black beans and black sesame. If you mix peanuts, it's much more savory than if you only used beans.

Now, put the boiled black beans, a handful of black sesame seeds, and a handful of peanuts in a blender, and then cool down the boiled water to a certain extent and grind it finely.

Remove the dough from the refrigerator and roll it with a rolling pin, sprinkling flour.

Put two sheets of dough in two colors and cut them into appropriate widths.

And quickly untangle the tangled ones.

Put the boiled beans and ground beans in a generous pot to set the concentration at a leisurely pace and start boiling. It may overflow, so please lower the heat as much as possible when it starts to boil.

Add chopped kalguksu and simmer stirring over low heat. You can burn it, so you have to stand next to the fire and stir it often.

Slice tomatoes and cucumber salad to garnish. I chopped cucumber with a chopping knife, so it's consistent and looks good.

When the kalguksu is cooked, season it with salt.
