Sea Squirt

I was initially intrigued by sea squirt because I had passed it in the Korean market and not once had I seen even the most wizened old crone pick one up. This was strange to me for two reasons. 1) Little old Korean ladies are always buying things like tripe, chicken feet, and massive jugs of mystery goo, and 2) that place looks like a swap meet for the Asian-American Centenarian Club. Sea squirt's unpopularity at such a venue indicated to me that it is indeed an odd food.

The sea squirt/ascidian, or Halocynthia, is a marine invertebrate filter feeder that preys on plankton in cool, shallow water. This hermaphroditic critter is eaten all over the world, but mainly in Japan (as "sea pineapple"), Korea, Chile, parts of Aboriginal Australia, and Europe, under the entirely more appetizing moniker "sea violet."

Traditionally the sea squirt is eaten raw, over rice, or in heavily spiced stews, so at first I figured I'd stay the course. It was, however, very difficult to find anything about the preparation online and certainly in none of my cook books. When inquired about a recipe, the snarky teenager at the seafood counter scoffed at me like cooking sea squirt was as natural as his emo haircut and then mumbled something entirely unintelligible. Upset that I clearly just got punked by a pimply sixteen-year-old who listens to bands like The Promise Ring and knows the names of multiple mascara brands, I hastened back to HQ.

Boom. A sea squirt. The smell was quite fishy, which instantly made me wary. Typically when buying seafood or choosing a life partner this odor indicates that freshness is a no-no. But hey, this is a sea squirt, and who was I to say this was a bad thing? The sea squirt's texture and color were very similar to that of a toad. And by that, I mean disconcertingly bumpy and brown (or deep umber if you want to get all fabulous about it.)

I began the dissection process. Now The Ivory Dragon is absurdly sharp and responsible for numerous hunks of skin missing from my fingers, so when I couldn't crack a dent in the "shell," my first thought was similar to that of Mama Cass's probable last: Clearly, I have bitten off more than I can chew. The only thing interesting was that certain orifices were releasing...yep, you guessed it, squirts of a clear liquid. So I changed up my strategy and tried the hairy left side (see picture) or what I like to call the merkin end. Butter.

Interestingly, the "shell" came off like the skin of a mango, revealing the rubbery inside and a whoooooole lotta juice. Here's the mess in all its glory:

No, this isn't your baby cousin's latest bowel movement after happening upon that unsuspecting gallon of Plenty of Pulp Tropicana. The bottom yellow...thing is the "edible" part. Upon first taste, I was quick to disagree. I read somewhere the Japanese ate sea squirt raw, so I crossed my fingers and dove in. The juice itself was briny and not unlike that of an oyster. The innards were tangy and almost caviar-like. The flesh itself was soft, slightly rubbery, and overwhelmingly soapy tasting. Now unless you're like my brother, whom my family suspects developed a four-letter lexicon at a young age because he just couldn't live without the ever-so-fresh tang of Irish Spring, the taste of ammonia is decidedly off putting. It was at this point I figured I'd hide the sea squirt in a cheesy mass of homemade pizza. How can pizza be bad, right? Plus, I'd already made the dough the day before.

White Sea Squirt Pizza

No Need to Knead Pizza Dough

1/4 tsp. dry active yeast
1 1/2 C. tepid water
1 1/4 tsp. kosher salt
1/4 tsp. sugar
2 T. olive oil
3 C. flour
corn meal, as needed

Combine all the ingredients in a bowl and stir with a spatula. The resulting dough should be slightly stiff and very sticky. Cover the mixture with Saran wrap and let it sit and rise for 12 hours. After this period, heavily dust a counter top and your hands and pat the mixture down to release the air bubbles. Quarter the dough with a pastry cutter or knife and form balls, keeping the "tucked" end down. Roll the balls out to a 8-10" round/square with a floured rolling pin. Apply corn meal liberally to an oven pan and slightly to the top your crust. Placing corn meal against corn meal, set your pizza crust on the pan. You're now ready to go.

Pickled Sea Squirt

3 sea squirts, julienned
2 C rice vinegar
1/3 C sugar

Pickling Spice Mix:

1 cinnamon stick
1 tsp. coriander seed
3 bay leaves
10 whole black peppercorns
10 whole white peppercorns
1 tsp. whole allspice
1 tsp. whole clove
1/2 tsp. crushed red pepper
1 large nub ginger, cut into coins

Add all the ingredients other than the sea squirt and bring to a simmer for 2 minutes. Add the sea squirt and simmer for 20 seconds. Drain, rinse, and dry.

Pizza Topping

2 T. extra-virgin olive oil
1 T. oregano, chopped
1 T. garlic, minced
handful of arugula
5-6 deli-style slices Monterey Jack cheese
large handful of Asiago cheese
pickled sea squirt, as needed
kosher salt & cracked black pepper

Preheat the oven to 450. At an extremely light simmer, saute the garlic and oregano in the oil until the garlic is translucent. Apply the oil very lightly to the top of the pizza dough. Season the dough with salt and pepper, then layer with the Monterey Jack cheese. Layer then with the sea squirt and the arugula and finally finish with another layer of Asiago cheese.

I'll be honest: I didn't really have the cojones or confidence that the squirt would be masked even by the cheese and garlic at this point. I wussed out and layered one half of the pizza. After 8 or 9 minutes in the oven, I removed the pizza and voila!

I was right: it was still impossible to escape the soapiness of the sea squirt. But hey, at least the other half was good! The chances of me eating this over rice or raw again are akin to that of me surviving a maximum security prison yard after arguing with a guy named Lord Shank over which bunk I'd get, but in retrospect I would probably eat it in a cioppino or bouillabaise.

Next post: Chicken feet.


  1. I demand posts more than once a week.

  2. A friend of mine put a sea squirt in front of me to eat and of course I ate it. THE most disgusting thing I've ever put in my mouth...

  3. i got sea squirts at a korean market out of curiosity, and yours was one of the very few links i found after googling "sea squirt(s)". thanks for the post and kudos to you for trying it out :)
    as for chicken feet: im sure you have figured out a suitable recipe by now, but chicken feet is in no way "strange" - its just chicken (well, of course?) with lots of bones. no strange smell or anything. just chicken. stew it for a long time, either in soup (we vietnamese do this to make our chicken Pho taste better), or in spices & seasoning (like Chinese dimsum). sea squirt is a lot more...unusual than chicken feet, i think.

  4. I love exotic foods i had a vivid dream about eating covered sea squirt nigri just before i woke up (maybe 20 minutes ago) and it was just as wrong in my Dream as in real life... its an experience you just can't regret enough.

  5. I just love how it looks now. You know I've never tried these sea squirts but I'd love to

  6. I had sea squirt yeasterday at a Korean cafe here in SLC. It was in a spicy monkfish stew. At first I just thought it was a little ball of monkfish meat. I gave one to my dad, he popped it in his mouth and dthen exclaimed in suprise as it squirted in his mouth. I then tried one and got the same experience. the squirt itself was impossible to chew as it was very leathery and tough. The juice it squirted was kinda bitter and not too pleasing. Interesting, but I won't be sad if I never experience a sea squirt again.

  7. I saw one of these on a "Food Show" and it was huge and very complex inside. It was sliced in half and offered raw to bystanders. I couldn't hear the sound so maybe it wasn't a sea squirt but someone nearby said it was.

    Tunicates, by the way, are yes, vertebrates, the very simplest. Even I recall this from high school.

  8. I watched a guy eat a sea squirt. He turned - literally - green. I've never seen anything like it before or since. People can be green.

    He died several years later of a rare form of thrombosis. I've always wondered if they were related.

  9. It actually looks pretty good as a pizza! Still not gonna eat it tho lol

  10. Did you test your sea squirts for toxic vanadium levels? Sea squirts are known to concentrate vanadium. Helen M Foster, MD

  11. Some things are simply not meant to be eaten, and while I’m sure some in water-surrounded lands would contest, the sea squirt is decidedly one of those things.
