Korean-Style Soup for a 1-Day Fast

Korean-Style Soup for a 1-Day Fast

This recipe makes a batch of soup that is good when dieting on a 1-day fast. If you divide it up into 7 portions, it should be enough to satisfy your tummy. It's vegetarian-friendly, too.

Ingredients: 1 day's worth

Dried shiitake mushrooms
5 g
3 L
● Dried tree ear mushrooms
15 g
● Cabbage
● Carrot
● Hot cooked white rice
200 g
1 medium
★ Gochujang
50 g
★ Red chili pepper powder (Korean)
1 tablespoon
★ Dashida
5 tablespoons
★ Salt
10 g
Sesame oil
a small amount


1. The night before your fast, soak the dried tree ear mushrooms in a bowl of water to reconstitute.
2. On that same night, rinse the sliced shiitake mushrooms, then put them in a pot filled with 3L of water, then cover with a lid.
3. In the morning, rinse the ● vegetable ingredients, chop into bite-sized pieces, then add the to the pot with the rice, and bring to a boil on high heat.
4. Add the ★ ingredients: salt, dashida, gochujang, and red chili pepper powder to the pot, stir until they dissolve, then cover with the lid.
5. When the pot comes to a boil, reduce to low heat and simmer for 15 minutes.
6. While the soup is simmering, put the egg in a bowl with 1 tablespoon of water, and vigorously whisk.
7. Turn off the heat, and with the bowl of whisked egg in one hand, and a ladle in the other, slowly pour the egg into the pot from a distance, then rapidly stir the pot with the ladle.
8. After adding the egg, transfer the soup to a bowl, drizzle in a small amount of sesame oil, then serve while piping hot.
9. Note 1: The color of Korean red chili pepper powder is very bright, but it is not spicy. I use 1 tablespoon.
10. Note 2: It's handy if you keep a stock of sliced carrots in the freezer, and add them to the pot as you need them.
11. Note 3: Since I didn't have cabbage, I used a bit of frozen Japanese leeks instead.
12. Note 4: If you can do without adding rice, go for it.
13. Note 5: It may be hard the first time, but try reducing the amount of salt a little at a time. You should aim to use less than 5 g of salt per day.

Story Behind this Recipe

Tree ear mushrooms contain plant-based fiber, while vegetables and eggs provide a perfect nutritious balance. The heat from the red chili pepper helps to fight against stubborn fat! It's also a great way to consume 2L of water, which is the recommended daily amount.
