Acitrón de Cidra Conventual

Ingredients

Equipment Needed

• •Sharp paring knife and heavy cutting board
• •Large glass or glazed clay bowl for soaking
• •Wide heavy stainless pot or tinned copper cazo
• •Slotted spoon or kitchen spider
• •Wire rack set over a tray
• •Clean glass jars with tight lids

Instructions

1. 1

   Cut the cidra

   Quarter the cidras lengthwise. Remove the pulp and seeds, then pare away only the rough outer yellow skin if it is thick and bitter. Do not remove the white pith. The pith is the candy. Cut the peel and pith into 1/2-inch cubes for picadillo and rellenos, or into short batons if you want pieces for rosca de Reyes.

2. 2

   Soak the bitterness

   Put the cut cidra in a nonreactive bowl and cover with cold water by two inches. Stir in the kosher salt. Let it rest for 12 hours, changing the water once or twice if you can. The water will smell sharp and floral. That is the bitterness leaving. If you skip this, the finished acitrón will fight every dish it touches.

3. 3

   Firm with limewater

   Stir the food-grade cal into 2 quarts cold water and let it settle for 15 minutes. Pour only the clear limewater over the drained cidra, leaving the chalky sediment behind. Soak for 6 hours, then drain and rinse the pieces under running water until the water runs clear. This is what gives the cubes their firm bite instead of a tired, mushy texture.

   Use food-grade cal only. Not construction lime, not garden lime. Pregúntale a las señoras del mercado, and if the vendor cannot tell you it is for nixtamal or pickling, do not buy it.
4. 4

   Blanch the cubes

   Move the rinsed cidra to a heavy pot and cover with fresh cold water. Bring to a gentle simmer and cook 10 minutes, then drain. Repeat this blanching two more times with fresh water each time. After the third blanch, the pieces should bend slightly without breaking and taste cleanly bitter, not harsh. If they still bite like medicine, blanch once more. No me vengas con atajos.

5. 5

   Start the syrup

   In a wide heavy pot or tinned copper cazo, combine 4 cups water, 2 cups of the cane sugar, the lime juice, and the sea salt. Warm over medium heat until the sugar dissolves. Add the blanched cidra and keep the syrup at the gentlest simmer for 45 minutes. The pieces should stay whole, with the edges beginning to look glassy.

6. 6

   Rest overnight

   Turn off the heat and press a round of parchment or a small clean plate over the cidra so every piece stays under the syrup. Cover the pot and let it rest 12 hours. This rest matters more than more boiling. Sugar needs time to enter the fruit. Force it with high heat and the outside candies while the center stays empty.

7. 7

   Strengthen the syrup

   The next day, lift out the cidra with a slotted spoon. Stir 1 1/2 cups cane sugar into the syrup and warm until dissolved. Return the cidra and simmer gently for 30 to 40 minutes. The cubes will look more translucent at the edges and heavier in the spoon. Cover again and rest 12 hours. This is the second soaking. Three means three.

8. 8

   Finish the candying

   On the third day, add the remaining 1 1/2 cups cane sugar to the syrup and warm until dissolved. Simmer the cidra 45 to 60 minutes, turning the pieces carefully once or twice. They are ready when the centers are translucent, the syrup falls from a spoon in a slow thread, and the cubes feel firm between your fingers. If you use a thermometer, the syrup should sit around 220F to 222F. The fruit tells you first.

   If the syrup tightens too fast and the fruit starts to wrinkle, add 1/2 cup hot water and lower the heat. Wrinkled acitrón means the syrup got stronger than the fruit could handle.
9. 9

   Dry or store

   Let the cidra cool completely in the syrup, at least 8 hours. For acitrón to dice into chiles en nogada or rosca de Reyes, drain the pieces on a rack for 12 to 24 hours until tacky but not wet, then cut as needed. For candy to serve by itself, roll the tacky cubes lightly in extra cane sugar. For keeping, pack the pieces in clean glass jars with enough syrup to cover and refrigerate.

10. 10

    Use with respect

    Dice small for chiles en nogada, because acitrón is punctuation, not the whole sentence. Fold batons into rosca de Reyes dough or set cubes beside queso fresco after a holiday meal. Save the clear cidra syrup for brushing rosca or sweetening aguas frescas. Recetas probadas y garantizadas.

Chef Tips

• •Ask for cidra or citron at a serious citrus stand in winter. A true cidra is heavy for its size, knobbly, fragrant, and mostly white pith inside with very little pulp. A regular lemon with ambition is not cidra.
• •Do not buy acitrón made from biznaga. If someone sells you cactus cubes for your rosca, understand what that means: a protected desert plant cut for a sweet that has another path. Use cidra. Así se hace y punto.
• •Piloncillo belongs in tacha and many almíbares. Not here. This acitrón needs cane sugar so the cidra stays pale, clean, and translucent. Piloncillo will darken the fruit and fight the walnut sauce in chiles en nogada.
• •Do not perfume the syrup with canela or clove if the acitrón is going into chiles en nogada. Those spices belong elsewhere. The cidra should taste like preserved citrus peel and sugar, not holiday punch.
• •For pantry storage, use a tested water-bath canning process. Otherwise keep the jars refrigerated. Sugar is powerful, but it is not magic. Saber cocinar es saber vivir.

Advance Preparation

• •Acitrón improves after three days in its syrup. Make it at least one week before rosca de Reyes or before you prepare the picadillo for chiles en nogada.
• •Stored under syrup in clean jars in the refrigerator, the acitrón keeps for 2 months. Keep every piece submerged.
• •For rosca de Reyes, drain and dry the batons 24 hours before baking so they do not bleed extra syrup into the dough.
• •For chiles en nogada, dice the pieces the size of small raisins. Too large and they dominate the picadillo.
