6) Preparation of curds

Required: water bath; thermometer; 2-l-beaker; 50-ml-beaker; glass rod; milk; lemon juice; rennin; cloth; sieve

Heat 1 l of milk in a water bath to the optimum temperature of 32°C. Dissolve one tablet of rennin in 10 ml of water and add it to the milk under stirring.
After ca. 40 minutes put the coagulated milk protein on a piece of cloth which lies upon a sieve. You should hold it over a sink!
Press the liquid from the solid curds and add lemon juice to your taste.


7) Preparation of yoghurt

Required: 2-l-beaker; fresh milk; yoghurt; thermometer; Bunsen burner

Bring 1 l of fresh milk to the boil and allow to cool to ca. 35°C. Add one teaspoon of natural yoghurt. After 4-5 hours the new yoghurt is ready. Add jam to your taste.
