How to check the quality of sour cream
High-quality sour cream consists of only two components – cream and starter culture, but manufacturers can add vegetable fats and thickener.
If vegetable fats are added, it is no longer sour cream, but a sour cream product, which must be labeled accordingly.
To check the vegetable fat content of sour cream, pour boiling water over a spoonful of sour cream in a transparent container.
A natural product will dissolve in boiling water and turn into milk. A product containing vegetable fats will leave a fatty sediment.
