Jinjujip YeouidoCold Soybean Noodles You Season Yourself

What kongguksu is

Cold noodles in a broth of ground boiled soybeans. A summer dish.

Look at the photo: the broth is thick and opaque. It looks like soy milk, and the important part is that it contains no sugar and no salt.

What it looks like

A round stainless bowl is filled to the brim with pale beige soy milk, with a neat mound of thin noodles in the center. The surface of the broth is covered with tiny bubbles. On the plate above sits a heap of napa cabbage kimchi in red seasoning, with an empty stainless bowl at the left. With no toppings, the color of the soy milk is all you see.

You season it yourself

The broth arrives completely unseasoned. If you taste it as it comes and decide it is bland, you have missed the dish.

How people eat it varies from person to person. You add salt or sugar to your own taste.

• Salt — the more common choice in Korea, from what I see. It sharpens the nutty soybean flavour
• Sugar — others prefer this, depending on region and habit. It makes the broth taste rounder and softer

There is no correct answer. Add a little, stir, taste, repeat. That process is how the dish is eaten.

Once the seasoning lands, the broth and the noodles start working together. Find that point and this becomes something you crave on every hot day.

If this is your first bowl

This will probably be unfamiliar. It is not difficult, though.

• It is cold. If you order expecting a hot noodle soup you will be surprised
• It is not spicy. There is no chilli in the broth. The only heat is the kimchi served alongside
• Season it yourself. As above. Skip this step and you will not taste what the dish is
• The noodles and broth are plant-based. The kimchi served with it may contain fermented seafood, so if you are vegetarian it is safer to leave the kimchi

Being honest about it

This is the part I most want to say.

One bowl is 15,000 won. That is expensive for a bowl of noodles. And it is the result of years of steady increases.

At the same time, a lot of similar kongguksu shops have opened recently. Even within Yeouido, more people now name somewhere else first.

So I would put it this way. If you are willing to give up a little, you now have options — and that makes going to Jinjujip a slightly harder decision than it used to be. The food has not got worse. The price and the alternatives both changed.

• If this is your first kongguksu — this is a good place to set your baseline. Start here
• If you already know the dish — whether it is worth 15,000 won is a judgement people will split on

Worth knowing before you go

• It is in basement level 1 of a building called the Yeouido Department Store. Despite the name it is an ageing commercial block, not a modern mall. Go downstairs
• Closed Sundays. Saturday ends at 7 PM
• There is a queue. Lunchtime certainly, and even around 3 PM expect a ten-minute wait
• It is a summer dish. Many shops run kongguksu seasonally, so check first if you are visiting in winter. Out of season, Beyond Vietnam, National Assembly branch, also in Yeouido, is a solid pho lunch instead
