Dulce de Biznaga Sonorense (Acitrón)

This is from Sonora. Also from San Luis Potosi, Queretaro, Zacatecas, anywhere the biznaga grows wild in the high desert. But Sonora claims the candy and the technique most fiercely, and Sonora is where I went to learn it, to a small town outside Hermosillo where a woman named Dona Concha taught me over two days in her kitchen with the back door open to the heat.

You need to understand what biznaga is before you cook it. It is a barrel cactus, Echinocactus platyacanthus, that takes 40 to 60 years to reach a size worth harvesting. It is now a protected species in Mexico because for a century the dulceros stripped the desert faster than the cactus could regrow. If you cannot source biznaga from a licensed cultivator, do not buy it from the wild and do not buy it from a vendor who cannot tell you where it grew. This recipe carries a responsibility. The candy is beautiful. The cactus is more beautiful.

The technique itself is patience. You soak the flesh in cal to firm the cell walls, the same cal we use for nixtamal. You rinse it. You blanch it. You cook it twice in a syrup of cane sugar and piloncillo with a stick of canela. Between cooks, you let it rest overnight so the sugar works its way in slowly. Rush the syrup and the outside hardens before the inside surrenders. La cocina no es decoracion, es trabajo, and this candy proves it across two days.

My mother kept a jar of acitrón on the top shelf of the alacena, brought back from a trip to Sonora before I was born. She broke off a piece for me on the morning of the Dia de Reyes and dropped the rest into the rosca dough. I have spent the years since trying to make sure the next generation knows what those translucent little cubes actually are, and what we owe to the desert that grew them. Saber cocinar es saber vivir.
