How to Cook Cardoons

Jump to Recipe Print Recipe
Cardoon

An especially white cardoon. They’re grown under mounds of earth to prevent photosynthesis and keep them white, also known as being blanched.

Cardoons. An giant thistle related to artichokes Darwin classified as a pest species. Every since I read about these in a book by Lorenza de Medici I wanted to eat them. It took until I was on the email list of a kooky Eastern European farmer that I got my chance to cook some.

I tried to dig up a copy of the original email from the farmer, but no dice. Basically, he wrote a couple pages comparing his excitement working with crops to a drug addict’s high and saying that a man he knew from Geneva Switzerland has sent him home with seeds. The last paragraph ended by saying: “Behold, Cardoon!”-followed by a painting he had made of the plant (he’s also an accomplished painter). We ordered some from him.

cardoons

When they showed up they were just like I imagined, giant stalks of celery, there was a catch. The stalks are covered in long spines (remember it’s a thistle), as well as painful barbed hairs, called glochids or trichomes, which are about the same as you’ll find on a cactus.

Cardoon

Note the tiny spines, the reason you should clean these by holding with a towel or heavy glove.

The glochids are pretty nasty since you won’t notice them until they’re dug in deep, hours later. I remember waking up at night after cleaning cardoons, hands covered in bloody pin pricks, splotches here and there on my sheets. Next time I cleaned them, I used a towel to hold them while I trimmed with my paring knife.

Speaking of cleaning them, I made a video for you, since it’s easier to understand with a visual example.

So why would you want to cook a plant that is covered in nasty spines? Because cooking them is a lost art, and an interesting process. Oh, and they taste like artichokes, but with a much higher yield, really useful if you want to sell dishes including them to guests.

Gnocchi with cardoon-tomato ragu

For a week at Lucia’s we served a bowl of teeny tiny gnocchi with cardoons simmered until tender with onions, garlic, wine and tomatoes, it was so good.

What can you do with them?

Lots of things, and I’m not going to go into all of them here. Here’s one technique and a sample recipe of what you can make with the finished preserves, an example of how I might use them in a kitchen.I do with them in restaurant scenarios. Without sharing complete recipes, after trimming the cardoons, here are some things guests and myself have enjoyed over the years, and a few other ideas:

  • Braised with tomato until tender and tossed with pasta, chili and olive oil (see above, make homer simpson noise)
  • One Italian classic is braising them in 3 inch or so pieces, then breading and frying, with some sort of dipping sauce, like a spicy tomato
  • At one restaurant, I served an alfredo style pasta with a cardoon infused cream, butter and parmigiano. The flavor transfers to cream very well, ending up tasting like artichoke alfredo.
  • Confit, covered with oil, garlic and herbs and cooked very slow until tender
  • Added to slow cooked meat braises, especially lamb
  • Havent tried it, but my friend Hank’s cardoon risotto looks great
Cardoons a la grecque

Crappy Iphone picture, I just never got around to re-shooting, maybe sometime this year.

Cardoons a la Greque

A gentle pickle method to preserve cardoons in the fridge. They taste like artichokes, with a much higher yield.
Prep Time45 mins
Cook Time45 mins
Course: Appetizer, Side Dish
Cuisine: Italian
Keyword: A la Grecque, cardoons
Servings: 4 cups

Equipment

  • Tall stainless steel pot (don't use aluminum)

Ingredients

  • 1 cardoon about 2 lbs
  • 3 large cloves garlic sliced
  • 1 cup flavorless oil
  • 3 cups dry white wine
  • 2 teaspoons sea salt or kosher salt
  • Bouquet garni of 2 fresh bay leaves and a small handful of fresh thyme wrapped in cheesecloth and tied together
  • 3 cups water
  • Water seasoned to taste with lemon juice as needed for holding the cardoons

Instructions

  • Peel the cardoon stalks of their spines and thorns on the side of each stalk using a paring knife, then gently remove the tough outer portion of the stalk, as you would peel celery. Cut the cardoons into ½ inch pieces and place them in the lemon water to prevent browning.
  • In a large, wide pan, heat the garlic on medium heat until lightly browned and aromatic, then add the cardoons, salt, wine, water, and herbs. Cover and cook for anywhere for 30 min to an hour, or until the cardoons are just tender. Transfer the cardoons to a labeled container, cover with their cooking liquid and weight down with a plate to hold them under the liquid and preserve them. Under their liquid the cardoons will keep for a couple weeks, they can also be frozen.
  • To serve the cardoons, reheat them with a bit of their juice and use as you would artichokes.

Notes

It's important not to leave the cardoons in water overnight after peeling. The water reacts with them and makes them curl, and after having their structure altered from peeling they'll twist and curl into a pile of useless fibers, although they could still be cooked with cream. 

As a garnish for fish

See a recipe using the preserved cardoons with monkfish in this post here.

    Cut a cardoon stalk Saturday and served a Sunday salad of
    small slices, topped with hard-cooked egg and a garlic-anchovy-egg yolk-red wine vinaigrette. Delighted to see your in al a Greque recipe that finished batches can be frozen. Gonna make a batch of that, I think, with some of my remaining stalk. I’ve been curious about cardoons for years and have collected a few recipes. Yours are inspiring me to plan more garden space next spring for cardoons.

      They are a fantastic vegetable, and you get a way better yield than with artichokes. Glad you like them.

        Dug 10 celeriac roots today. The 2 lbs of feeder roots taste like the bulb, I found. Plan to use them to make stock with other vegetables. I know the green stalks can be used for stock or soup but what about the feeder roots?

    See joewiercinski on instagram or my FB page, joe wiercinski. Yep, planted Apium graveolens. The big ones, softball size, weighed about a pound. Can I share the FB photo to you on FB?

    Yesterday, because of looming cold weather, I dug the last of two massive cardoons started from seed in my Pennsylvania garden. The stalks are in the fridge waiting for me to try a couple of your ideas for serving them to friends who like the taste of artichokes. In a very large pot fitted with a bed of compost, the roots, covered with dampened chopped leaves, will spend the next six months in an unheated garage so they won’t freeze. In the spring, will the plant grow anew in a sunny bed? Fingers crossed.

Sometimes I forget we have good traditions in Amer Sometimes I forget we have good traditions in America too. Case in point: bourbon. 

TIL about American traditions, and the role of the white oak in aging. Tasted some of that sweet nectar too. 

The rye finished in rum barrels smells like pure maple syrup 🤤. @angelsenvy

Summer veg PSA: One of the edible plant parts I co Summer veg PSA: One of the edible plant parts I cover in my book you might not know are squash and pumpkin shoots. 

Tender and delicious, these are eaten around the world. The US is still coming around, but I see them occasionally at farmers markets. 

I like to give them a dip in boiling water to wilt them quick, then toss them with some fat or stir-fry them quick. The little curly-cues make them look like fairy tale veggies to me.

Shaved cattail rhizomes with smoked trout, chickwe Shaved cattail rhizomes with smoked trout, chickweed, lemon, hickory nut oil and tarragon from the @wild.fed shoot. 

I spent a couple days trying to cook the rhizomes, and it works, but raw is my favorite prep. 

I add some smoked trout both for the salty pop and because it’s fun to mix aquatic edibles. Runner bean flowers for a splash of color.

Long, fun day snatching crayfish out of the water Long, fun day snatching crayfish out of the water by hand with Sam Thayer and @danielvitalis for @wild.fed 

Daniel and Sam were the apex predators, but I got a few. 

Without a net catching crayfish by hand is definitely a wax-on wax-off sort of skill. Clears your mind. 

They’re going into gumbo with porcini, sausage and milkweed pods today.

Working all day on preps for cattail lateral rhizo Working all day on preps for cattail lateral rhizomes and blueberries for this weeks shoot with @wildfed 

Been a few years since I worked with these. Thankfully Sam Thayer dropped a couple off for me to work with. They’re tender, crisp and delicious. 

Sam mentioned their mild flavor and texture could be because they don’t have to worry about predators eating them, since they grow in the muck of cattail marshes. 

I think they could use a pet name. Pond tusk? Swamp spears? Help me out here. 😂

Nature makes the coolest things.

I liked the staff meal I made for Mondays shoot so I liked the staff meal I made for Mondays shoot so much we filmed it instead of the original dish I’d planned. 

Cooked natural wild rice (not the black shiny stuff) is great hot, cold, sweet or savory. It’s a perfect, filling lunch for a long day of berry picking. 

I make them with whatever I have on hand. Mushrooms will fade into the background a little here, so I use a bunch of them, along with lots of herbs and hickory nut oil + dill flowers. 

I’m eating the leftovers today back up in the barrens (hopefully) getting some more bluebs for another shoot this week w @wild.fed
