Shropshire Blue is a blue cheese made from pasteurised cows' milk and uses vegetable rennet. The orange colour comes from the addition of annatto, a natural food colouring. It has been described as a cross between Stilton and Cheshire. Made in a similar way to Stilton, it is a soft cheese with a sharp, strong flavour and a slightly tangy aroma. It is slightly sour but sharper than Stilton and generally creamier.
