A consumer group, Which?, has tested many foods and found supermarkets often win.

In a test of cheddar cheese, Tesco's cheese was the favorite.

Tesco's cheese got 78% and was praised for its flavor and texture.

Testers liked the salt and flavor of the cheese and its crumbly, creamy feel.

The Tesco cheese costs £4 for 350g, which is about average.

In another test, supermarket instant coffees did better than well-known brands.

Marks and Spencer and Waitrose coffees were better than Nescafé and others in a blind test.
