Membrillo en Almíbar Oaxaqueño

This is from Oaxaca, from the Sierra Norte where quince trees grow in the cool valleys above the city and the fruit comes down to Mercado 20 de Noviembre and Mercado de la Merced in baskets every October. The yellow skin still wearing its gray fuzz, the fruit so hard you can knock two together and they sound like wood. That is when membrillo en almíbar belongs on the stove. Not in July. Not in March. October and November, when the mercado tells you it is time.

The almíbar is built on piloncillo, the unrefined cane sugar pressed into cones in the trapiches of the Sierra. Piloncillo is not brown sugar. It is cane juice cooked down until it crystallizes, full of molasses and minerals, and it carries a smoky depth that white sugar will never give you. Together with canela, real canela, the soft stick from Sri Lanka that you can crumble between your fingers, not the hard cassia bark that most US markets sell as cinnamon, and a few cloves, the syrup turns into something that smells like Oaxacan Christmas.

The quince does the rest. You poach it slowly. Slowly. Quince does not give up its color the way an apple does. It starts pale yellow and over an hour and a half it deepens into the rose-pink that every senora in the Central de Abastos will tell you is the only correct color. Pull it too early and you have undercooked fruit. Let it go and the magic happens.

My mother had a recipe for membrillo in her notebook, but she had it as ate, the paste, not en almíbar. The almíbar version I learned from Senora Felicitas in Tlacolula, who served it to me on a Sunday afternoon with a slab of queso fresco from Etla on the side. She said her mother made it the same way and her grandmother before that. The combination of the sweet poached fruit and the cool salty cheese is one of those Oaxacan inventions that sounds wrong on paper and works completely on the plate. Saber cocinar es saber vivir.
