Dahi (Indian set curd)

Facts

Safety

• Inherits the general dairy-lactic-fermentation safety floor documented. Documented risk factors:
  (a) raw-milk vs. pasteurized-milk considerations — as with all fresh set-milk ferments, starting from unpasteurized milk carries materially higher pathogen risk that acidification alone does not reliably eliminate within typical short-incubation timeframes;
  (b) adequate acidification — an intermediate "danger-zone" hold before the starter establishes dominance (a particular risk given dahi's traditionally ambient, season-variable incubation temperature, which is less tightly controlled than a dedicated thermophilic yogurt incubator) can allow competing/pathogenic organisms a foothold;
  (c) refrigeration — dahi is a fresh, perishable product, especially in warm-climate ambient incubation/storage conditions, and should be refrigerated promptly once set. Safe-practice guidance: use pasteurized milk unless the raw-milk risk profile is explicitly accepted and understood; boil milk fully before cooling to incubation temperature (a standard, widely-practiced step that also serves a safety function alongside its texture role); avoid prolonged ambient holds outside the intended incubation window, particularly in warm climates; refrigerate promptly once set; discard on off-odour, visible mould, or gas production. All numerics above are (illustrative); no regulatory-grade pH/temperature/duration thresholds are asserted.

Method

Dahi (Indian Set Curd)

• Whole cow's or buffalo milk — ~1 L
• Dahi starter ("jaman"/"jag") — a small spoonful (~1–2 tbsp, illustrative) of previous-batch dahi, or a plain commercial dahi/yogurt as a starter if no back-slop is available — SAFETY CONTROL, see linked Variant

1. 1

   Step 1

   Bring the milk to a full boil, then let cool to a warm (not hot) incubation temperature.

2. 2

   Step 2

   Whisk the back-slopped starter into the cooled, warm milk until evenly distributed.

3. 3

   Step 3

   Pour into an earthenware or steel vessel.

4. 4

   Step 4

   Cover and place in a warm location, undisturbed.

5. 5

   Step 5

   Incubate until a firm curd sets — timing varies noticeably with ambient temperature and season (faster in warm weather, slower and often cooler-set in winter).

6. 6

   Step 6

   Check for a clean-set curd (firm, a light tang on smell, minimal whey separation).

7. 7

   Step 7

   Refrigerate once set, or consume fresh at room temperature per household preference.

8. 8

   Step 8

   Reserve a small portion as the starter for the next batch.
