History of Yogurt1st made hundreds of years ago in the middle east my nomads.Fermented milk from animals and turned it into yogurt to eat.Probably discovered by someone trying to heat milk to preserve it over a fire.

Types of YogurtSet Yogurt- this type of yogurt is incubated and cooled in the final package. Firm jelly like texture.

Stirred Yogurt- incubated in a tank and final coagulum is broken by stirring before cooling. Less firm then set yogurt (like a thick cream). A little reformation of coagulum will occur after packaging.
