The diagram below shows the process of yogurt making. Summarise the information by selecting and reporting the main features and make comparisons where relevant. Write at least 150 words.

The flow chart illustrates how

yoghurt

is produced. At the first step in the

yoghurt

production,

milk

is heated up to 100 degrees Celsius by the gas. After that, it is chilled until lightly warm in the pan.

Following

this

, some old

yoghurt

is poured into cold

milk

and

then

whisked together until it dissolves and the mixture becomes smooth. As far as the two main components are mixed together, it is poured into slightly warmed

milk

. At the final stage in manufacturing,

yoghurt

is wrapped in some towels or cloths to save its required temperature.

Subsequently

,

this

almost-ready product is abandoned for four hours to let it set.

At the end

, the completed product -

yoghurt

is stored in the fridge or any refrigerator to keep it chill.

Overall

, the process includes two ingredients and eight steps, which can be grouped into three main stages: preparing the

milk

, mixing the ingredients, and completing the process with ready

yoghurt

.
