Many has problems digesting direct milk. Yogurt is best alternative. As its made by milk, has all its healthy properties.
I also made it in home @dindar. Simple procedure:
Boiling half litre milk.
Allow it to cool.
When lukewarm it will be, putting one tablespoon yogurt. And mix finely
Place it in place nearby stove, (I put it in nearby stove, so some very low moderate heat comes, like in any place in kitchen much hotter place in our home. I put it above refrigarator also, as it passes some heat.
Takes 12/14 hours to set. Have to be very careful not to shake/move it untill it sets fully.
Your homemade yogurt is ready to eat.
Put it in normal cooling part of refrigarator. we can use it for 4/5 days.
