Food glossary



Yogurt is milk that has had a combination of harmless bacteria added to it, traditionally Lactobacillus bulgaricus and Streptococcus thermophilus. The bacteria causes the milk to ferment and thicken and gives it its characteristic tangy taste.

Yogurt was originally produced to extend the keeping qualities of milk but now is enjoyed simply for its taste and versatility in cooking. Yogurt can be made from whole or skimmed milk. Over the past 10 years new bacterias have been used in yogurt-making, to make 'bio yogurts', these are reputed to aid digestion.

The majority of yogurts sold in the UK are 'live' yogurts - this means that they contain live bacteria when they are sold and up to the use by date. Rather confusingly the label 'live' on a yogurt usually refers to the fact that one of the new types of bacteria has been added (a 'bio' yogurt).

Uses: Natural yogurt can be added to fresh fruit and cereals for breakfast. It can be used to make dips and salad dressings, as a garnish for soups and used to add a creamy taste and texture to sauces and curries. It can be used as a substitute for cream or ice cream or as a topping for fresh fruit, meringues or gateaux.

To store: Keep in the fridge and consume by the use by date.
