Six Different Methods of Setting Curd

Six Different Methods of Setting Curd

This comprehensive guide preserves traditional techniques for setting perfect homemade curd (yogurt) using various starters like buttermilk, thick curd culture, butter, and even lemon juice. The recipe emphasizes the critical importance of temperature control—using lukewarm milk known as 'sumretu'—and vessel selection, such as porous clay pots to absorb moisture for a thicker texture. Whether you prefer the classic culture method or the rich butter-lined technique, these historical methods ensure a versatile, creamy staple essential for Indian cuisine.

Ingredients

  • 4 cups Whole milk (Originally '1 Sher'. Converted to approx 1 liter/4 cups.)
  • 1 tablespoon Thick buttermilk (Chhas) (Starter for Method 1. Use fresh, thick buttermilk.)
  • 1 tablespoon Thick Curd/Yogurt (Starter) (Starter for Method 2 & 4. Originally '1 to 1.25 tola'. Ensure it is strained of water.)
  • 1 tablespoon Butter (unsalted) (For coating the vessel in Method 3 & 4. Should be cold and hard.)
  • 1 1/2 teaspoons Lemon juice (Starter for Method 5. Originally '1 to 1.5 spoons'.)

Instructions

  1. 1Pour the pure milk into a saucepan and bring it to a boil. Let it bubble 4 to 5 times to ensure it is fully heated. Remove from heat and let it cool until it reaches a lukewarm temperature (historically called 'sumretu' or 'fuku'). Test by dipping a finger: it should feel warm but not burn, nor should it be cold.
  2. 2For the first method: Once the milk is lukewarm, add 1 tablespoon of fresh, thick buttermilk (chhas). Mix thoroughly. Pour into a bowl and set aside. Note: In summer, use slightly less starter; in winter, you may need slightly more.
  3. 3Take a clean, dry vessel (a black clay pot is traditional and recommended as it absorbs excess water, making the curd firmer). Smear a thick layer of stiff curd (free of water) all around the inside of the vessel. Pour the lukewarm milk into this coated vessel. Do not stir excessively.
  4. 4Clean and dry a bowl thoroughly. Smear a thick layer of hard butter inside the bowl. Pour the lukewarm milk into the butter-lined bowl. Critical: The milk must be exactly lukewarm; if too hot, the butter will melt and ruin the texture; if too cold, it will not set.
  5. 5Mix a small amount of the lukewarm milk with half the quantity of the curd starter first, then mix this back into the main body of milk. Smear a thin layer of butter inside a dry bowl. Pour the milk-curd mixture into the butter-lined bowl.
  6. 6Ensure the milk is lukewarm. Add 1 to 1.5 teaspoons of lemon juice and mix well. Note: If the milk is too hot, it will curdle instantly (split); if too cold, it won't set. This method takes slightly longer to set than using curd culture.
  7. 7Cover the vessel from your chosen method and place it in a warm, draft-free spot. Allow it to sit undisturbed for 6 to 8 hours (or overnight) until the curd is set firm.
