Cajeta de Leche Quemada Sonorense

Ingredients

Equipment Needed

• •Wide heavy-bottomed 6-quart pot, ideally tin-lined copper or enameled cast iron
• •Long-handled wooden spoon or paddle
• •Chilled saucer for testing consistency
• •Clean glass jars with lids for storage
• •Fine-mesh strainer (in case you need to strain at the end)

Instructions

1. 1

   Choose the right pot

   Pour the goat's milk into a wide, heavy-bottomed pot. Wide, not tall. You want surface area for the milk to reduce. A 6-quart Dutch oven or a copper cazo is right. A tall narrow pot will keep you stirring for five hours instead of three and the caramel will still come out pale. The Sonoran ranch women who taught me this used wide tin-lined copper because the heat travels evenly and the milk does not scorch on the bottom. La cocina no es decoracion, es trabajo.

   Do not fill the pot more than halfway. When you add the baking soda the milk will foam up violently. If the pot is too full, you will spend the next hour cleaning the stove.
2. 2

   Add the sugars and aromatics

   Set the pot over medium heat. Add the piloncillo, granulated sugar, and the canela stick. Stir with a long-handled wooden spoon until the piloncillo dissolves completely. Piloncillo is unrefined cane sugar pressed into a cone, and it carries a molasses depth that white sugar alone cannot give you. This is what makes cajeta taste like cajeta and not like dulce de leche. If you cannot find piloncillo, dark brown sugar is a compromise. Not an upgrade.

3. 3

   Dissolve the baking soda and add it carefully

   In a small cup, stir the baking soda into the 2 tablespoons of cold water until it dissolves. When the milk is just starting to steam at the edges, pour the baking soda solution in slowly while stirring. The milk will foam up dramatically. Keep stirring until the foam settles. The baking soda neutralizes some of the acidity in the goat's milk, which keeps it from curdling over the long cook and helps it brown into that deep mahogany color. Skip this step and your cajeta will break, separate, and taste sour. No me vengas con atajos.

   The foam will rise fast. Pull the pot off the heat for a moment if you need to. Once the bubbles settle, return it to medium heat and keep going.
4. 4

   Bring to a gentle simmer

   Adjust the heat so the milk simmers steadily but does not boil hard. Lazy bubbles across the surface, not a rolling boil. A hard boil will scald the milk solids on the bottom and turn the whole pot bitter. The cajeta needs heat that is patient. Stir every five minutes for the first hour, scraping the bottom and the corners of the pot each time. The milk will be thin and pale and you will wonder if anything is happening. Trust the time.

5. 5

   Stir through the long reduction

   After the first hour, the milk will begin to take on a faint cream color and the volume will have dropped noticeably. Now you stir more often, every two or three minutes. The Sonoran women I learned from set a low stool next to the stove and stayed there with their wooden paddles, talking, drinking cafe de olla, telling stories. This is a dish that asks you to sit with it. Around the second hour the color will deepen from cream to pale gold and the pot will start to smell like browned milk and brown sugar. That is the lactose caramelizing. Saber cocinar es saber vivir.

6. 6

   Watch for the leche quemada turn

   In the third hour, the cajeta will darken quickly. Pale gold becomes amber. Amber becomes the deep tobacco-brown that gives leche quemada its name, burnt milk, though it is not burnt, it is caramelized to the edge. From this point you do not leave the stove. Stir constantly. The bubbles will get thick and slow and shiny, like lava. Drag the spoon across the bottom of the pot and you will see the bottom for a full second before the cajeta closes back over the trail. That is your sign.

   Test on a cold saucer. Drop a small spoonful onto a chilled plate. Let it sit for thirty seconds. Run your finger through it. If it holds a clean line and the cajeta does not run back together, it is ready. If it runs, give it five more minutes.
7. 7

   Finish and cool

   Pull the pot off the heat. Fish out the canela stick. Stir in the pinch of sea salt and, if you are using it, the spoonful of mezcal or Bacanora. The alcohol cooks off almost immediately against the residual heat and leaves behind a faint smokiness that anchors the cajeta to the Sonoran high desert where the agaves grow. Let the cajeta cool in the pot for fifteen minutes, then ladle it into clean glass jars. It will thicken further as it cools. Cada estado, su propia cocina, and this one is Sonora's. Asi se hace y punto.

Chef Tips

• •Goat's milk is the recipe. Cow's milk gives you dulce de leche, which is a different thing, an Argentine cousin, not a Mexican original. The faint tang of goat's milk is what gives cajeta its character. If you can find raw or unhomogenized goat's milk at a farm stand or a serious cheese shop, use it. The supermarket carton works but the flavor is less complex.
• •Piloncillo comes in dark and light cones. Use the dark (oscuro) for this. It is what the ranch cooks reach for and the molasses depth is the whole point. Chop it with a heavy knife or smash it in a clean kitchen towel with a hammer. It dissolves once it hits the warm milk.
• •Cajeta keeps in clean jars in the refrigerator for at least two months and the flavor only deepens. Warm a spoonful in the microwave for ten seconds before serving and it loosens right up. It also freezes well, though I have never had a jar last long enough to freeze.

Advance Preparation

• •Cajeta is a make-ahead dish by nature. It keeps refrigerated for two months in clean glass jars and the flavor only gets better after a week.
• •If the cajeta thickens too much in the refrigerator, warm a jar in a pan of hot water or microwave gently for ten to fifteen seconds. It returns to a pourable consistency.
• •For holiday gifts, ladle the warm cajeta into small jars while still loose, seal, and the cajeta will set at the proper spoonable thickness as it cools.
