Yes, blue cheese melts, but it behaves differently from other cheeses due to its unique texture and composition. Blue cheese has a high moisture content and is veined with mold cultures, which create pockets of air within the cheese. When heated, blue cheese becomes creamy and smooth rather than stretchy like mozzarella or cheddar. The mold veins don't melt in the same way as the rest of the cheese, often leaving a slightly chunky texture. This melting quality makes blue cheese ideal for sauces, toppings, and fillings, as it adds a rich, tangy flavour and a luxurious, creamy consistency without becoming overly runny. When used in burgers, blue cheese melts just enough to infuse the meat with its distinctive flavour, while retaining a bit of its structure for a delightful contrast in texture.
