An essential ingredient in many Sicilian recipes, the humble-looking caper packs a hefty dose of umami in a compact package. Typically found jarred and floating in brine in the U.S., these grayish-green shriveled-up buds are harvested from the Capparis spinosa bush (also called Flinders rose), a perennial plant with fleshy, rounded leaves and white or pinkish-white flowers. Producers also sell caper berries, the plant's large seed pods, and caper leaves.
To learn more about capers, I caught up with food/wine travel consultant, private chef, and writer Linda Sarris (aka @TheCheekyChef). Linda leads frequent tours to Sicily's island of Pantelleria. There participants get a first-hand look at caper production and even visit a caper museum. Linda also shared her favorite caper recipe: caponata.
What is your background?
I'm a Greek American who moved from New York City to Sicily. I've been living full-time in Palermo for about eight years.
I started a food and wine travel company here because I was working as a private chef. And then, when I moved to Sicily, I had to reinvent myself a little bit. Not so much private cheffing work here, especially for an American, but I've written two travel guidebooks for Moon Guides, which is part of Hachette. And so I write about travel in Sicily and food. I organize some week-long trips and retreats throughout the year, usually in Sicily in the Aeolian Islands in the summertime and Pantelleria, usually in spring and fall. I also do a market tour in Palermo. So, lots of different things, but always food- and wine-travel related.
What drew you to Sicily?
I ended up here. I got a scholarship to work in Sicily after attending a cooking school in New York, and then I just fell in love with the place. So, I came here in 2011 and have been studying Sicilian food since then.
Let's talk about capers. What is your interest in the plant?
I like meeting farmers or producers and learning about the products we use in cooking here. As I'm working in tourism, I want to be able to talk about the culinary culture here. I need to know what the items are, how they're made, and how they're grown.
I think the plants are incredible, and you see a lot of them in the places where I often travel for work. So, in the Aeolian Islands, Salina is a famous place for its capers, followed by Pantelleria, the island off the coast of Trapani. So those are the two most famous, although you do see them growing around a lot of the Mediterranean areas.
And then, producer-wise, I've met a lot of people who just cure them at home for their own use. And I've always worked closely with La Nicchia, which is a big producer in Pantelleria. They have always been at the head of developing new and caper-related products. They were probably the first ones ever to sell caper leaves in a jar. They do freeze-dried capers and caper powder. They sell seeds. They're always kind of innovating with new things they can do.
They opened a caper museum in Pantelleria. When I bring guests there, we visit the museum, do tastings, and learn about the process because capers were such a big business for that island.
And so I've always been excited about the plant and how we use it in cooking. It's always one of the main things people bring back from Sicily because it's such a specialty ingredient, travels well, isn't super expensive, and is better than what they might find at home.
What exactly is a caper?
The part that we eat as the caper is the unopened bud of the flower of the plant. It's a really incredible plant. They are pruned when you're cultivating them, but usually, they grow wild in the cracks of the road and come out of walls.
The plants that are actually thriving the most are the ones that are not cultivated and planted by people. It's really like a bush but has these long crawling vines. And the cool thing is that the season is really long, so the more you pick them, the more they'll produce. And you can actually pick the buds that are the capers from April until almost September or October.
The plant produces a lot. And so we usually sell here in Sicily, two different sizes, really tiny ones, and kind of a bigger one that's almost ready to open up into the flower. You'll see the whole progression of how it grows just on one vine, which is kind of cool. So you'll see the little buds in the leaves, bigger buds, and flowers. Once the flower opens up, the fruit of the caper grows out of the flower. And in English, we call it a caper berry or, in the Sicilian dialect, cucunci. It looks like an olive on a cherry stem. That's the fruit. And that's where all the seeds are. So what usually happens is birds eat that, travel around, and make new plants with the seed.
If you don't pick the bud, it opens to the flower. If you remove the flower, it goes back to making buds. But if you let the flower open, fruit comes out. It usually depends on what product you want, how quickly you pick it, and what level you let it develop.
How are capers typically prepared?
What we eat is not just straight off the plant. It has to be preserved, and usually, that involves sort of pickling it. So, either in a brine or a saltwater pickle or just packed in sea salt, which is what most people in Sicily do. It's usually just covering them with salt, rotating the batches until they lose some of their bitterness, and removing the liquid that comes out. Eventually, they could be preserved for eating, but you still have to soak them before you eat the ones packed in salt.
Most people here preserve and save and eat the buds of the flowers, the caper, and the berry. More recently, some companies have been curing the leaves as well. It's not as common. Maybe you would see that in someone's house, but that's not a very common thing you'd find in a store. But the same thing is packed into salt and maybe put under vinegar or oil in a jar.
Why are capers an important part of Sicilian cuisine?
I think they represent the earthy and even bitter and salty flavors that people like here. Capers grow wild and can be foraged food, so maybe that's why they became so popular. It was something people could pick without having to buy ingredients like that. We use them in so many different ways here, but I don't think just adding a caper makes a dish Sicilian.
How are capers used?
What's nice is that they can be used in everything—vegetable dishes, meat, and fish. And now we start to see them more in desserts. In Pantelleria, a few gelaterias make chocolate caper and oregano gelato. Then, on Salina, they do candied capers, which I don't see anywhere except on Salina, and that's really delicious. They put them with cannoli instead of chocolate chips at the end. It looks like a chocolate chip, but it's a candied caper.
People think the flavor of caper is salty, but it's only salty because you have to process it that way. But the ones in Pantelleria are very earthy and floral, so you can have capers in a dessert because it's not necessarily salty. It's caper flavor. It's not salt.
They're very versatile. We use them in a ton of recipes. They're a staple pantry item that most families have at their house. Most people will cure them for themselves.
What are your favorite caper dishes?
I like caper pesto because you can really taste the flavor. When you're going to use the capers in larger quantities, you do have to soak them, not just sprinkle them through a dish.
Capers tend to be in every single tomato salad. And in other parts of the Mediterranean, it's a staple—the tomato salad with capers in it. In Pantelleria, they have a typical salad made with potatoes, oregano, olives, and capers. It's in caponata, which is one of the most famous dishes of Sicily.
I like experimenting with some of the new things like caper powder. Caper leaves are a really beautiful way to apply garnish on top of fish. The seeds are interesting, and the caper berries are, too. They're beautiful as a little snack on a charcuterie platter. But they're really nice in cocktails, too, as a garnish instead of an olive in a martini or gin and tonic.
How do you use caper powder?
I put it on roasted vegetable dishes, such as pumpkin or eggplant, and I use it on fish as well, just as a little sprinkle. Depending on how you make it, it's kind of earthy and a little bit salty.
When you tour caper farms, what do you hope participants take away?
That there is a lot of work. One of the things that makes it more expensive is that they're all picked by hand. They're picked in the warmest months of the year, so spring through summer. The people who pick them, too, have to pick them while kind of crouching down. So it's physical work. And usually, they get paid per kilo that they pick. Historically, it has not been a great job to have because it's a lot of work and paid very little. But that's also why the little capers cost more than the big ones. It's more work to pick them; even if they're not priced by weight, they're priced by quantity.
If you step on the branches, caper plants stop producing. It kind of grows out from the root like little spider legs on the ground, like a starburst. And the people have to pick them with their legs spread out, and they're leaning over and reaching. It's just physically a little difficult to pick.
That's why it's harder to cultivate them yourself. Because once you put people in the field on top of them, the plant's not willing to give you as much.

Linda's favorite caper recipe: caponata
The noble dish was originally made with a fish called capone (no relation to Al), a small type of mahi-mahi, which gives it the now outdated name caponata. As many Sicilian dishes evolved and were modified for the masses, they changed to cheaper peasant dishes that typically used eggplant. There are variations of this recipe from town to town, from family to family, and sometimes it is made with artichokes in the springtime instead of eggplant, red pumpkin in winter, or even with apples.
My recipe is adapted from cooking with my mentor Fabrizia Lanza, the research of eating every version of caponata in sight, and other tips and tricks I've picked up along the way.
I snuck in a few bits of chocolate to thicken up the sauce as an homage to the tradition of chocolate-making in southeastern Sicily in the town of Modica. In the province of Trapani, it is often topped with toasted almonds, and the tomato is optional. The secret is cooking each ingredient separately and then mixing them together in the end to marry all of the flavors.
- INGREDIENTS
- 1 small red onion, sliced
- 1 eggplant (dark black/purple Italian aubergine, which is oblong or teardrop-shaped) cut into 1-inch cubes
- 2 stalks of celery, sliced into small bite-sized pieces
- 3T. extra virgin olive oil
- 1/4c. red wine vinegar
- 2T cane sugar
- 1t high-quality tomato paste (estratto in italiano)
- 1/2c. pelati (whole, peeled canned tomatoes), roughly chopped
- 1/4c. Sicilian green olives, pitted and halved
- 1T capers packed in salt (the best ones come from the Sicilian islands of Pantelleria or Salina), soaked in warm water, then squeezed dry
- 2T. unsweetened chocolate, chopped into small pieces to easily melt down
- black pepper
- vegetable oil to deep fry
- sea salt to taste if needed
RECIPE (serves 5)
Blanch the chopped celery in heavily salted boiling water (without a lid) until bright green but still crunchy; strain out and shock in ice water before setting them aside for later.
Deep fry the eggplant cubes until they are dark brown (not burned, but much more than just golden). Allow the eggplant to float on the oil, and when they are finished frying, blot them on a few layers of paper towel to absorb the extra oil. Frying the eggplant helps it keep its shape and not turn your caponata into a mushy pâté.
In a shallow pan, sauté the red onion with some EVOO on medium-low heat until softened.
Add the red wine vinegar, sugar, and tomato estratto to pickle the onions and create a thick agrodolce sweet-and-sour sauce. Add the pelati, give it a stir, and simmer over low heat for 10 minutes.
Season with black pepper, but do not add salt.
Throw in a few chocolate bits (this is my secret) and let them melt into the sauce to give it some creaminess.
When cooled down, toss the fried eggplant in a large bowl with the sweet-and-sour onion/tomato mixture, adding the prepped capers and olives (these two ingredients should never be heated).
At the last moment, mix in the celery to keep its green color.
Check seasoning and add additional sea salt if necessary.
The olives and capers can both bring additional salt to this dish, so be careful with your seasoning.
Serve as a room-temperature side dish or on toasted bread as an appetizer. Caponata will taste even better the next day.
