Without making a separate broth, sliced pickled cucumber is steeped in bottled water to draw out its salt, which is then used directly as the soup base. Seasoned sweet and sour with vinegar and sugar, you can enjoy its crisp texture and deep flavor in a clean, refreshing way. It is wonderful to drink chilled on hot days or served with thin wheat noodles mixed in.

Finishing the cold pickled cucumber soup
Finish the cold pickled cucumber soup



Because pickled cucumber is salty, you need to soak it in bottled water to draw out the salt.
Pour 2 1/2 cups of bottled water over 1 sliced pickled cucumber and soak for about 30 minutes. (Do not discard this water; use it directly as the cold soup base.)
As salt leaches out from the sliced pickled cucumber, it becomes pleasantly seasoned to eat, and since the salt has seeped into the liquid, you do not need any extra salt.
Do not throw away the water used to steep the pickled cucumber; use it just as it is.
Add 1 tbsp vinegar and 1/2 tbsp sugar, dissolve them, and taste.
If the soup tastes too strong, add more water, and adjust with sugar or vinegar so it becomes nicely sweet and sour.
Finally, add the large green onion, red chili pepper, and toasted sesame seeds to finish.
