Cockles are in peak season right now, plump and full of flavor.
Boiled and served with a seasoned soy sauce, they make a wonderful side dish, and leftover cockles turn into a great cockle bibimbap the next day.
The key to enjoying cockles at their best is boiling them just right, so here’s an easy guide covering everything from cleaning to boiling.
Ingredients
- Cockles – as much as you like (fresh Korean cockle clams, typically in season from around February to April; small clams can be substituted if cockles aren’t available)
- Water – enough to fully submerge the cockles (for soaking)
- Salt – 1 T (dissolved into the soaking water)
- Water – enough to fill the pot (for boiling)
- Salt – 1/2 T (for the boiling water)
(1 T = 15 ml / 0.5 fl oz, 1 t = 5 ml / 0.17 fl oz)
How to Make It

1Put all the cockles in a large bowl, fill it with water, and add a spoonful of salt, stirring until it dissolves.

2Cover the bowl so no light gets in and let the cockles soak for about 30 minutes to purge any grit.TipWe covered the bowl with a cutting board. Recreating a dark, ocean-like environment like this helps draw impurities out of the cockles.

3Once they’ve finished soaking, rinse the cockles several times under running water. It’s important to keep rinsing until no more grit comes out — I rinsed mine about 10 times.

4Fill a pot with water, add about half a spoon of salt, and bring it to a boil.


5Once the water is at a rolling boil, cook the cockles over high heat for only about 1 minute.TipBoiling them too long will make the texture tough and chewy.

6Rinse the boiled cockles briefly in lukewarm water.TipCockles lose some of their flavor if rinsed in water that’s too cold or too hot, so lukewarm water keeps both the texture and taste at their best. Adjust the rinsing water temperature to your preference.

We like to enjoy them with a seasoned soy sauce on the side.

Wrapping a spoonful of rice in seaweed along with a cockle and some seasoned radish namul makes for a really satisfying bite.

I’m saving the rest of the cockles to make cockle bibimbap tomorrow.
