Cardureu is a soft pecorino cheese made using vegetable rennet, characterised by an aromatic taste of thistle, appreciated also by vegetarians. In the past, before the discovery of animal rennet, a thistle flower head wrapped in a small bag with holes was put in the milk to obtain curd and left to rest for the night. The coagulating properties of this plant are known to old school cheese-makers.
Its average weight is between 2 and 2.5 kg, with a delicate and flavoured taste, without using any preservatives, additives or anti-mould products (as in all Garau cheeses), it is made using milk from free-grazing sheep farmed in Sardinia. Excellent served with thistle honey and Su Pani Pintau (traditional bread).
