Yogurt

Facts

Safety

• Yogurt made from pasteurized milk at correct incubation temperature has a well-documented, low-risk safety profile — no significant acute-hazard risk factors documented beyond standard dairy-hygiene practice. Safe-practice guidance:
  (a) use pasteurized milk — raw-milk yogurt carries materially higher pathogen risk (Listeria, Salmonella, pathogenic E. coli) not reliably eliminated by the short (hours) fermentation/acidification window;
  (b) hold milk at target incubation temperature (~43-45°C) promptly after inoculation to minimize time in the bacterial "danger zone" (4-60°C) before the starter culture establishes dominance;
  (c) target pH ≤4.6 at set completion (standard consensus dairy-safety threshold).

Method

Yogurt (Set Yogurt from Pasteurized Milk)

• Whole pasteurized cow's milk (or sheep/goat/buffalo, regional) — 1 L — SAFETY CONTROL (pasteurized), see linked Variant
• Live yogurt with active cultures, as back-slop starter (or a commercial thermophilic S. thermophilus + L. delbrueckii subsp. bulgaricus starter) — ~2 tbsp per litre, illustrative

1. 1

   Step 1

   Heat the milk to ~85°C and hold briefly, then remove from heat — this pasteurizes and denatures whey proteins for a firmer set.

2. 2

   Step 2

   Cool the milk to the target incubation temperature, ~43–45°C — SAFETY CONTROL, see linked Variant.

3. 3

   Step 3

   Temper the starter with a little of the warm milk, then stir it evenly through the rest.

4. 4

   Step 4

   Cover and hold undisturbed at ~43–45°C for 4–8 hours; do not stir or move the vessel while it sets.

5. 5

   Step 5

   Check for a clean set (the curd pulls away from the vessel wall and the whey runs clear).

6. 6

   Step 6

   Refrigerate promptly once set to arrest further acidification.

7. 7

   Step 7

   Optional: strain through cloth for a thicker Greek/labneh/süzme-style yogurt.
