MEXICO CITY — Regardless that it is unlawful, bars of acitrón are stacked in practically each stall on the Merced market in Mexico Metropolis.
They seem like lemon bars. However they’re items of barrel cactus which have been chopped up after which seeped in vats of sugar till they’re crystalized.
Edith Hernández Torres, who runs a store right here, wraps hers in cellophane. She says acitrón is particular, that it tastes nothing just like the candied lemon or candy potato or the pineapple she additionally sells.
“It has a chewy texture,” she says, “like one thing roasted.”
The Mexican authorities started banning the sale of acitrón within the early 2000s. That is after they discovered that the biznaga cactus — a species of barrel cactus — was at risk of extinction on account of overexploitation.

Hernández is aware of acitrón is unlawful, however her prospects demand it. When NPR asks if she would not really feel unhealthy about promoting one thing that is going extinct, she shrugs.
“Our complete planet goes extinct,” she stated.
As she speaks, MarĂa Julia Gutiette picks up a bar of acitrĂłn. She does it gently, like she’s selecting up a bar of gold.
Her husband and this nation have been born on the identical day: Sept. 16. So, yearly, Gutiette buys the pears, the peaches, the pink pine nuts and the acitrĂłn to make the make chiles en nogada, a conventional dish that’s eaten from August to early October.
“Traditions are the salt and pepper of life,” she stated. “They’re that additional one thing that makes life extraordinary.”
When she says this, her eyes tear up. She by no means had chiles en nogada rising up as a result of the elements have been too costly. However then, she studied, she turned a nurse and moved to Mexico Metropolis.
“If you develop up and make your individual cash, you save for good issues,” she stated. And so for Independence Day, she needs to deal with her household to one thing particular. And the chiles en nogada, she says, should be made with acitrĂłn.
“Cacti do not develop like grass”
On the Nationwide Autonomous College of Mexico’s botanical garden, there’s an entire part devoted to barrel cactuses. It is the form of cactus that performed an vital function in Mexico even earlier than the Spanish launched the sugar that made it so candy. The cactus seems within the Aztec codices and the identify comes from a Nahuatl phrase which means a pot lined in spines.
“In Mexico, now we have greater than 150 species of biznaga,” stated Salvador Arias, a biologist who runs the botanical gardens. Most of them are going extinct within the wild.
He factors towards the golden barrel cactus whose spines make it seem like a rising solar. Mexico constructed a hydroelectric dam, the place these golden barrel cactuses dwell and right away their surroundings was destroyed and this species was nearly worn out.

Among the cacti are 40 years previous and so they attain to your thigh. Others are 8 years previous and they’re tiny, simply the scale of your fist.
“These cacti do not develop like grass, as a result of their metabolism is particularly gradual,” Arias stated. “It is so gradual they may develop millimeters a 12 months.”
This implies farming the biznaga is neither sensible nor worthwhile, in order that they’re harvested from the wild. That has left dozens of species on the verge of extinction.
“However I am an optimist,” he stated. “I imagine that cacti have developed up to now to thrive in contrasting environments. I believe they will do it once more.”
He walks towards his assortment of nopales, the cactus that adorns the Mexican flag, the cactus that’s an on a regular basis staple in Mexican kitchens. However this species is flourishing due to an evolutionary adaptation.
“The nopal is modular,” he stated. It grows in a form of chain, so not like the biznaga, people can minimize off and eat the latest shoots with out killing the entire plant.
“The Soul of Mexico”
The chef of the restaurant Azul doesn’t use acitrĂłn. However his chiles en nogada are legendary.
They’re so vital that after they start serving them in August, the desk cloths go black and the silverware goes gold.
“It is a yearly ritual,” chef Ricardo Muñoz Zurita stated.

Chiles en nogada, a conventional dish that’s eaten in Mexico from August to early October. Produced from poblano peppers, full of meat, pears, peaches, pine nuts and typically — however not on this case — acitrĂłn, and bathed in nogada, a walnut cream sauce, and garnished with pomegranate seeds and parsley.

First, the waiters deliver out a tray of poblano peppers topped with a inexperienced, white and pink bow. And after they place one on the plate, they douse it with a creamy walnut sauce, as silky as melted white chocolate.
“This plate is the soul of Mexico,” stated Muñoz. “It tastes just like the motherland, like independence. It tastes like Mexico itself.”
Muñoz makes a recipe from 1821, which is what was served to the independence hero AgustĂn de Iturbide in Puebla proper after signing a treaty that consummated Mexico’s independence.
However a number of years in the past, the chef stepped away from that recipe and stopped utilizing biznaga. As a substitute, he began utilizing candied chilacayote, which is a sort of squash.
“In fact, it would not have an effect on the ultimate style,” he stated. Certainly, he performed blind style checks and nobody might inform the distinction.
“However Mexicans maintain tight to traditions,” he stated. “Should you realized to make it out of your grandma or mother and so they used acitrĂłn, I perceive why they might wish to preserve utilizing it.”
However he feels a accountability to not use it, as a result of he needs barrel cactuses to outlive within the wild.
“We people have the good energy of adaptation,” he stated.
To avoid wasting the barrel cactus, he stated, we might be sensible to make use of it.
