Blue Cheese - There are blue cheese variants of many of the cheese listed above. What puts them into the blue cheese category is that penicillium roqueforti - a blue mould - is added to the cheese at various stages in the making process. Sometimes it is added to the milk at the start of the process in other cases it is sprayed onto the curds before being shaped. Normally the cheese will be pierced with stainless steel needles to allow air into the body of the cheese which then activates the blue mould and starts to break down the protein which in turn creates the blue mould. The process is a way of accelerating the normal development of the cheese and means that quite strong tasting cheese is produced within a few months. Blue Stilton is perhaps the best known blue cheese produced in the UK but there are now more than 70 different blue cheeses being produced within the UK. Other notable British examples are Shropshire Blue, Blue Cheshire, Blue Wensleydale, Dovedale, Buxton Blue, Blacksticks Blue and even Blue Leicester! Imported examples include Roquefort, Gorgonzola, Cambozola and Danish Blue.
