Sigeumchi Namul (Seasoned Spinach)

Step 1 of 4

Blanch the spinach

Bring a large pan of salted water to a rolling boil. Add the spinach and push it under with tongs for 30 to 45 seconds, just until it collapses and turns deep green.

Any longer and it goes grey and slippery. This is quicker than it feels like it should be.
