Ingredients

  • 200 g (1 cup) millet or fine cornmeal
  • 1.5 L (6 cups) water, divided
  • 100 g (1/2 cup) sugar
  • 1/2 tsp active dry yeast
  • 1 tsp lukewarm water, for the yeast

Method

  1. In a saucepan, whisk the millet or cornmeal with 500ml (2 cups) of the water to form a smooth slurry with no lumps.
  2. Bring the remaining water to a boil in the same pan, then whisk in the slurry.
  3. Reduce heat and simmer gently, whisking often, for 30-35 minutes, until thickened into a smooth porridge-like consistency.
  4. Remove from heat, stir in the sugar until dissolved, and let cool to lukewarm (around 30-35°C / 85-95°F).
  5. Dissolve the yeast in the teaspoon of lukewarm water and let sit for 5 minutes until foamy, then whisk into the cooled mixture.
  6. Pour into a clean jar or pitcher, cover loosely (not airtight, to allow gases to escape), and leave at room temperature for 2-3 days to ferment, tasting daily until it reaches a pleasant, mildly tangy flavor.
  7. Strain through a fine sieve or cheesecloth to remove any solids, then refrigerate.
  8. Serve chilled, whisking or shaking well before pouring, as it separates on standing.

Introduction: Boza is a thick, mildly fermented, low-alcohol grain drink with roots going back centuries across the Balkans and
beyond. In Bulgaria it is especially popular in the colder months and pairs naturally with the plant-based rhythms of
Orthodox fasting, since it is made purely from grain, water, sugar, and a touch of yeast, with no animal products of
any kind.

Cultural Background: Boza is a thick, mildly fermented, low-alcohol grain drink with roots going back centuries across the Balkans and

Tips: Boza should ferment just enough to develop a mild tang, but not so long that it becomes strongly sour or alcoholic — taste it daily. Covering loosely rather than sealing tightly is important, as the fermentation produces gas that needs to escape. Boza naturally separates in the fridge; always stir or shake well before serving.

Variations: Add a pinch of ground cinnamon or roasted chickpea powder on top when serving, a traditional garnish in some regions. Use wheat flour instead of millet for a different regional variation, common in Turkey and Albania as well. Adjust the sugar level to taste, as boza can range from lightly sweet to quite sweet depending on preference.

Storage: Refrigerate in a covered jar for up to 5 days; the flavor continues to develop slightly as it sits.

Reheating: This drink is served cold and is not reheated.
