amsterdam - Pesto must be made from basil, pine nuts, parmesan cheese, garlic and olive oil. But there are often other ingredients in a jar.
Research by the British Consumers Association shows that there are potatoes and sometimes even ground bamboo. The prescribed olive oil is also often replaced by the variant with sunflowers. Also the expensive Parmesan is often exchanged for another species. Cashew nuts sometimes serve as a replacement for expensive pine nuts.
In some pots were even carrots processed to make it as cheap as possible, writes the Daily Telegraph.
The union bought 12 jars in the (English) supermarkets on which stood 'premium pesto alla Genovese'.
And more expensive does not always mean better. Also in the more expensive pots were ingredients that they would never stop in Genoa.
The bond Which! always advises to read the (tiny) small print on the pot. There are all the replacement ingredients.
There is also alarmingly a lot of salt in the pesto. In fact, there is less salt in a McDonalds hamburger: 1.5 grams per serving against 1.2 grams at the restaurant.
