Ingredients
For the Corn Base
- 2 cups dried white field corn (maíz blanco), rinsed
- 8 cups filtered water, divided
- 1 teaspoon calcium hydroxide (cal), optional for traditional nixtamal-style softening
- 1/2 cup piloncillo or brown sugar, finely grated
- 1 inch fresh ginger, peeled and sliced
- 1 cinnamon stick
For Fermentation and Finishing
- 2 tablespoons reserved cooking liquid (natural starter)
- 1/4 cup fresh lime juice
- 2 tablespoons honey or sugar to taste
- Pinch of fine sea salt
Directions
- Combine the rinsed corn with 6 cups of water and the calcium hydroxide in a heavy pot. Soak for 8 to 12 hours, then drain and rinse thoroughly.
- Return the soaked corn to the pot with 6 cups of fresh water, the ginger, and the cinnamon stick. Bring to a boil, reduce heat, and simmer uncovered for 35 to 45 minutes until the kernels are tender and beginning to burst.
- Strain the corn, reserving 2 tablespoons of the cooking liquid. Let the corn and liquid cool to room temperature (about 75°F).
- Transfer the cooked corn, the reserved cooking liquid, and the ginger and cinnamon to a blender. Add 2 cups of fresh filtered water and blend until smooth and creamy, about 90 seconds.
- Pour the blended mixture into a clean glass jar, cover loosely with cheesecloth, and let it ferment at room temperature for 48 to 72 hours, until lightly fizzy and pleasantly tangy.
- Strain the fermented liquid through a fine mesh sieve or cheesecloth into a pitcher. Stir in the lime juice, honey, and salt. Adjust sweetness to taste.
- Chill thoroughly for at least 4 hours. Serve very cold in tall glasses, over ice if desired.
- Refrigerate any leftovers in a sealed bottle for up to 5 days; flavor will continue to deepen.
Cook’s Notes
- Use dried field corn rather than sweet corn for the most authentic, earthy flavor and proper fermentation.
- If fermentation is slow, move the jar to a warmer spot (around 80°F) and stir once daily; you should see small bubbles forming by day two.
- For a thinner drink, blend in an extra 1 to 2 cups of water before fermenting; for a creamier texture, reduce the initial cooking water.
- Taste at 24-hour intervals during fermentation, as longer fermentation yields a tangier, more beer-like drink.
- Always use a clean, non-metallic container for fermentation to avoid off-flavors and unwanted reactions.
