Gosari Namul is one of the most widely loved namuls (Korean vegetable side dishes) in Korea. It's also frequently used in making bibimbap.

When I was young, Gosari Namul was often seen on our dinner table because everyone in the family liked it. (With other namuls, usually there was at least one person in the family who didn't like that particular kind.) It's also a must-have namul on Korean holidays such as New Year's Day and Korean Thanksgiving.

The nutty flavor and aroma of sesame oil really brings out the earthy taste of Gosari. Although Gosari Namul is a vegetable dish, it feels pretty substantial without being too heavy, and contains many beneficial nutrients. It's great for vegetarians and healthy eaters!

Optional Ingredients & Substitution
It's best to use Soy Sauce for Soup (Gook Ganjang) but if you don't have it, use regular soy sauce.
If 2 tbs of regular sauce (for 70g of dried gosari) doesn't make it salty enough, use salt to season it instead of adding more regular soy sauce.

Frequently Asked Questions

Can I blanch before soaking?
Some people reverse the whole soaking and blanching process (i.e., blanch for 30 minutes first and soak overnight. Then wash.) Either way should work.

What if I bought pre-blanched gosari from the market?
Technically, you don't have to blanch it again. Wash 2-3 times thoroughly and squeeze water out before using.
However, many Korean moms quickly blanch it again because they don't necessarily trust the vendor's sanitation standards, or they just want to make sure it's free from possible bacteria.

My gosari is not soft enough after blanching it. What's wrong?
- Depending on how dry the gosari is and how long you soak it, blanching time may vary. So you may have to blanch for a longer time.
- It also depends on your texture preference.
- If you don’t soak or blanch enough, it will be tough. If you overdo it, it will be mushy.

How much gosari should I cook?
50 g of dried gosari yields a handful of blanched gosari (after blanching and squeezing out water). Since it's usually served as a small side dish, you can probably just cook 50g of dried gosari for 2-3 people. But, if you want to use this as a main dish or you are just in love with gosari, you'll want to use more. If you buy pre-blanched ones, a handful is good for a side dish for two.
