This traditional Mongolian cultured yogurt captures the tangy, slightly effervescent character of tarag, a beloved everyday dairy across Mongolia. Made by fermenting whole milk with a live culture until thick, creamy, and pleasantly sour, it can be eaten plain with honey, sipped as a cooling drink, or stirred into sauces for grilled meats. The slow, warm fermentation gives it a depth of flavor that store-bought yogurt rarely achieves.

Ingredients

For the cultured yogurt

  • 8 cups (2 L) whole cow's milk, preferably not ultra-pasteurized
  • 1/4 cup (60 ml) plain whole-milk yogurt with live active cultures, OR 2 tablespoons kefir grains, OR 1/4 cup reserved previous batch
  • 1 tablespoon heavy cream (optional, for a richer mouthfeel)
  • 1 small pinch fine sea salt (optional, helps the curd set firmer)

For finishing and serving

  • Cheesecloth or a clean cotton napkin for draining
  • Raw honey, for drizzling
  • Fresh berries or lightly toasted oats, for topping
  • Cold water or fruit juice, if blending into a drink

Directions

  1. Pour the milk into a heavy-bottomed pot and slowly heat it to 180°F (82°C), stirring often to prevent scorching; this step denatures the whey proteins and produces a thicker final yogurt.
  2. Remove the pot from the heat and let the milk cool to 110°F (43°C), about 30 to 40 minutes; an ice-water bath can speed this up if you are in a hurry.
  3. Whisk about 1/2 cup of the warm milk into the starter culture in a small bowl until completely smooth, then pour that mixture back into the pot and stir gently to distribute.
  4. If using kefir grains, pour the inoculated milk into a clean glass jar, drop in the grains, and cover with a breathable cloth secured with a rubber band. If using yogurt starter, pour into a clean jar or pre-warmed thermos and seal the lid loosely.
  5. Cover the container with a clean kitchen towel and let it ferment in a warm, draft-free spot (75 to 85°F / 24 to 29°C) for 12 to 18 hours; the yogurt is ready when it smells pleasantly tangy and has just set, holding a spoon standing upright.
  6. Transfer the jar to the refrigerator and chill for at least 4 hours; this halts the fermentation and firms the texture further.
  7. For a thicker, spoonable tarag, line a fine-mesh sieve with cheesecloth, set it over a bowl, and spoon in the chilled yogurt. Refrigerate and let it drain for 2 to 4 hours until it reaches the consistency you like; reserve the tangy whey for bread dough or drinking.
  8. Stir the finished yogurt gently to smooth it out, then serve cold on its own, drizzled with honey and topped with berries, or blend with cold water and a little honey for a refreshing summer drink.

Cook’s Notes

  • Use the freshest milk you can find; ultra-pasteurized milk yields a thinner, less flavorful yogurt because the proteins have been heavily denatured.
  • Sanitize jars, spoons, and lids with boiling water before use; stray bacteria can throw off the flavor or cause the batch to spoil.
  • In traditional Mongolian homes, tarag is often fermented in a covered pot near the cookstove, where residual warmth holds it at a steady temperature for 12 to 24 hours.
  • The longer you ferment, the tangier and slightly more effervescent the yogurt becomes; aim for 12 hours for a mild flavor and up to 24 hours for the robust, traditional taste.
  • Save 1/4 cup of each batch in a clean jar in the fridge to inoculate the next one, the way Mongolian families have passed their starter down for generations.
