How to Make Yogurt at Home Step by Step

Ingredients

  • 1 liter milk
  • 1–2 tbsp plain curd/yogurt with live culture (starter)

Best starter:

  • Fresh homemade curd
  • Or plain unsweetened yogurt

Step-by-Step Method

1. Boil the Milk

  • Pour milk into a heavy-bottom pan.
  • Bring to a boil on medium flame.
  • Stir occasionally to avoid burning.

Precautions

  • Do not over-burn milk at the bottom.
  • Full-fat milk gives thicker curd.

2. Cool the Milk

  • Let the milk cool until warm.

Ideal temperature:

  • Warm enough to dip finger comfortably for a few seconds.
  • Around lukewarm, not hot.

Important Precautions

  • If milk is too hot:
    • bacteria die,
    • curd won’t set.
  • If milk is too cold:
    • fermentation becomes slow.

3. Add the Starter

  • Take starter curd in a bowl.
  • Add a little warm milk and mix smoothly.
  • Pour into the milk.
  • Mix gently.

Precautions

  • Use fresh starter only.
  • Sour starter makes sour curd.

4. Fermentation

  • Cover the container.
  • Keep in a warm place for 6–10 hours.

In Summer

  • Usually sets faster.

In Winter

  • Keep inside switched-off oven with light ON.
  • Or wrap with cloth.

5. Refrigerate

  • Once set, refrigerate for 2–3 hours.
  • This improves texture and taste.
