One evening this spring, on the Upper East Side of New York City, I had my first and last taste of iguana.
I was at , an institution more than a century old, devoted to āthe scientific exploration of land, sea, air, and spaceā. Its membership rolls feature polar explorer Robert Peary and primatologist Jane Goodall. Its dim, wood-panelled rooms boast trophies: the skin of a lion baggedĢż by Teddy Roosevelt; a flag that visited the moon in 1969.
I had been invited to the clubās annual dinner at the Waldorf Astoria (dress code: āblack tie or native dressā). There was a bar, and a table laid with crackers and cruditĆ©s, but most people were milling around a table in the corner where Gene Rurka, the clubās resident chef, was carefully arranging plates of grilled lionfish, Asian carp sushi and iguana meatballs with a plum dipping sauce. An actual iguana splayed out on a bed of greens made a feral centrepiece.

Rurkaās menu, reflecting this yearās theme ā āOceans: The Current of Lifeā ā was centred around invasive sea creatures. We chatted while he put on the finishing touches. Rurka first felt inspired to cook for his fellow explorers back in the 1990s. āWe were getting boring,ā he says. He sought out recipes that he thought better reflected the clubās adventurous style. Stuffed eyeballs. Fried tarantula. Snakes. Invasive species were the natural next step: unlikely yet ecologically sustainable dinner choices.
Eat the enemy
Take the Asian carp (actually a catch-all term for several species). Decades ago, the US imported them to filter pond water in Arkansas fish farms. The carp rapidly spread throughout the country, outcompeting many native fish. While popular sources of protein like salmon and tuna struggle with declining numbers due to overfishing, eating Asian carp seems like the obvious solution, says Rurka. āIf you took the next three months and ate 20 tonnes of that fish, you would eliminate the need for killing 20 tonnes of another fish thatās being hammered.ā Sliced into sashimi and sushi, itās āas fine a grade as youāre ever going to getā.
The carp had a mild taste, somewhat like halibut or yellowtail. I could imagine it quietly fitting into a lunchtime sushi selection. The iguana was harder going, dry and chewy, and all the while the meatballsā dead cousin stared at me with its beady eyes.
Members of the Explorers Club arenāt the first to try eating invasive species. Over the last few years, conservationists and chefs alike have warmed to the idea, as a way to push culinary boundaries while helping battered ecosystems. When these creatures land in unfamiliar environments, the consequences can be devastating: a study earlier this year suggested that invasive species are now the second biggest cause of extinctions. Controlling their numbers often proves tricky and expensive. Why not make the invaders useful instead?
āI see this as a way of engaging people,ā says Joe Roman, a conservation biologist at the University of Vermont and the āeditor ānā chefā of recipe site āItās helping bring invasives into peopleās minds and getting them to think about it, and then to go out and have fun and actually have a really good meal.ā

The public was slow to catch on, says Roman, but interest has been boosted by recent culinary trends like the locavore movement. Now there are a handful of restaurants around the US with invasives on the menu. In Miami, pop-up restaurant Prey offers dishes like āfinger lickin'ā Asian carp ribs and feral pig wrapped in potato skin. Alewife in Maryland serves up snakehead cakes, wild boar sliders and blue catfish tacos. The pollen of wild fennel, a plant that has displaced native competitors in California, is baked into bread served at Rich Table in San Francisco.
Invasives have started to appear on the periphery of my own life. just a mile north of my office turns out to sell wild boar dumplings. While lunching at , I noticed that the menu now advertises garlic mustard, a problematic weed collected just a few towns away.
Unfamiliar foods can be tough to swallow. Most servers of invasive species, like the Explorers Club, happily advertise their food for what it is. But if conservationists want invasive species to go mainstream, they may have to rebrand their ingredients. It worked for the gruesome-sounding Patagonian toothfish, which is consumed daily under the pseudonym Chilean sea bass.
Hold the iguana
Thatās the thinking of Louisiana chef Philippe Parola. For several years, heās campaigned to rebrand Asian carp as silverfin. Now, heās working to market the carp to caterers and restaurants. Figuring out how to process the fish to make it easy to use, conducting market research and developing the tastiest recipes are all part of what he calls ābreaking the codeā of a new species. āItās just a matter of educating the public and getting the taste to the public,ā he says. āIf it is good, then you canāt lose.ā
āMaybe someday there will be a drive-through invasive species restaurant, but I wouldnāt hold my breath at this point,ā Roman warns. Many people are hesitant to try an such an unfamiliar delicacy even when itās placed right in front of them. When I asked a few Explorers Club staffers which invasive was their favourite, assuming they would give enthusiastic endorsements, one claimed she hadnāt had the chance to try anything yet, while another admitted: āI personally stay far, far away from the exotics table.ā
I would go back. Iām looking forward to trying what comes next. I might skip the iguana next time, mind you.
Recipes
Here are a couple of recipes that feature invasive species as their main ingredients. For more invasive recipes, visit
Ragondin Ć l'Orange
Ģż
Species: Nutria (Myocastor coypus)
Region of origin: South America
These river-dwelling rodents were introduced to the US West Coast as an alternative to mink in the mid-1900s. Around 1.5 million nutria were trapped annually for the fur trade in its heyday, but nutria fur is no longer in fashion and wild populations have rocketed.
Ingredients
| Mirepoix
65g chopped celery 65g chopped carrots 65g chopped onion |
Bouquet Garni
1 bunch fresh thyme 1 bunch parsley Bay leaves Ģż |
| Nutria
2 hind saddle portions of nutria meat 90g brown sugar Salt and pepper to taste |
Other
480ml white wine 1 tbsp soy sauce 240ml orange juice 2 tbsp vegetable oil Orange zest (finely chopped) |
Method
Place oil, mirepoix and bouquet garni in a pan; set aside. Rub each saddle with brown sugar and salt and pepper to taste. Place saddles on top of other ingredients in pan. Place, uncovered, in a 175 °C oven (Gas Mark 4) for 15 minutes.
Remove from oven and deglaze with white wine, soy sauce and orange juice. Cover pan with plastic wrap and again with aluminium foil. Place back into oven for 45 minutes to one hour until meat is tender. Break meat off bones. Place on plate then garnish with vegetables, pan drippings and orange zest.
Makes 4 servings.

Kuzdu Blossom Jelly
Ģż
Species: Kudzu (Pueraria montana)
Region of origin: Japan and China
This perennial, deciduous vine was introduced to the US as a forage crop for cattle in the 1930s. Most of the plant is edible, which is just as well: with a growth rate of 30 centimetres a day, it's one of the fastest growing plants in the world, smothering everything it grows on, including large trees.
The delicate purple flowers used to make this jelly have a fragrance reminiscent of grapes. Spoon over cream cheese, or melt and serve over waffles and ice cream.
Ingredients
250g kudzu blossoms
1 litre boiling water
1 tbsp lemon juice
50g packet of powdered fruit pectin
1kg sugar
Method
Wash kudzu blossoms with cold water. Drain well and place in a large bowl. Pour boiling water over the blossoms and refrigerate overnight (or 8 hours). (The jelly will be pink, but note that the blossom liquid is gray until lemon juice is added.) Strain the liquid through a colander into a covered casserole container; discard blooms. Add lemon juice and pectin and then bring to a rolling boil over high heat, stirring constantly. Stir in the sugar. Return to a full boil and stir constantly for one minute. Remove from heat and skim away foam with spoon. Quickly pour jelly into hot, sterilized jars, filling to a centimetre from top. Wipe jar rims and cover with metal lids and bands. Steep in boiling water for 5 minutes. Cool jars on wire racks.
