How to make Yogurt

Simple homemade yogurt using live cultures. Ready in under 24 hours with precise temperature control at two key stages.

Quick answer

Heat milk to 82C to kill competing bacteria and denature whey proteins for a thicker set. Mix the live starter into the cooled milk and pour into jars ready for incubation. Hold the inoculated milk at 40-45C undisturbed for 6-8 hours until a firm gel forms. After 1 day, refrigerate the set yogurt for at least 2 hours to firm texture and develop flavour.

Safety

  • • Do not add the starter until the milk cools to the recommended range or the culture may fail.
  • • Keep the jars covered and undisturbed during incubation so the gel network can set properly.
  • • If the chilled yogurt smells unpleasant, shows colored mold, or turns slimy, discard it.

Step-by-step

Day 0

Step 1: Heat the Milk

Heat milk to 82C to kill competing bacteria and denature whey proteins for a thicker set.

  • Heat to 82C Pour milk into a heavy-bottomed saucepan and heat over medium, stirring constantly, until it reaches 82C.
  • Hold and Cool to 43C Hold at 82C for 2 minutes, then cool to 43C before adding the starter culture.

Step 2: Inoculate

Mix the live starter into the cooled milk and pour into jars ready for incubation.

  • Temper the Starter Mix the starter yogurt with a small amount of warm milk to prevent cold shock before adding to the main batch.
  • Inoculate the Batch Stir the tempered starter gently into the full pot of cooled milk.
  • Pour into Jars Ladle the inoculated milk into clean glass jars. Cover loosely. Do not shake or move once poured.

Step 3: Incubate

Hold the inoculated milk at 40-45C undisturbed for 6-8 hours until a firm gel forms.

  • Choose Your Incubation Method Select a method that maintains a stable 40-45C for 6-8 hours.
  • Incubate Undisturbed Leave jars completely undisturbed at 40-45C for 6-8 hours.
  • Check the Set After 6-8 hours, gently tilt one jar to confirm a firm gel has formed.
Day 1

Step 4: Chill and Verify

Refrigerate the set yogurt for at least 2 hours to firm texture and develop flavour.

  • Refrigerate Transfer the set jars to the refrigerator for at least 2 hours to firm the texture.
  • Taste and Verify Taste the chilled yogurt and reserve 2 tbsp as starter for your next batch.

What to look for

  • • Heating: The milk reaches 82-85C without boiling over. That heat step denatures proteins so the finished yogurt sets more firmly.
  • • Before adding starter: The milk cools to 43-45C and feels warm, not hot. Hotter milk can weaken or kill the live culture.
  • • After incubation: The jar wobbles as one mass instead of sloshing like liquid. A little pale whey on top is normal and not a spoilage sign.

Troubleshooting

  • The yogurt stays thin. The incubation temperature was too low or the jars were moved during the set. Incubate longer in a steadier warm environment and avoid disturbing the jars.
  • The yogurt tastes too sour. It incubated too long or too warm. Stop the ferment earlier next time and chill as soon as the set looks right.
  • The texture is grainy or broken. The starter was added while the milk was still too hot. Use a thermometer and wait for the milk to cool fully before inoculating.
  • A little whey separates on top. Mild over-incubation or a firm set during chilling. Stir it back in or strain the yogurt for a thicker style.

Storage

Seal and refrigerate the jars for at least 2 hours before eating. Reserve a little plain yogurt as starter for the next batch.

Shelf life: up to about 2 weeks refrigerated

Serving suggestions

  • • Eat it with fruit, honey, jam, or granola.
  • • Use it in dressings, marinades, or savory dips.
  • • Strain it for a thicker yogurt or soft labneh-style spread.
