Some people might say that Gorgonzola is the strongest, while others might argue that Roquefort is the king of blue cheeses. However, there is no definitive answer to this question. It really depends on personal taste and preference. Some people might find Gorgonzola to be too strong, while others might find Roquefort to be too mild. Ultimately, it comes down to what each individual person prefers. So, if you're looking for a blue cheese that packs a punch, then Gorgonzola might be the right choice for you. But if you're looking for something a little more mellow, then Roquefort might be a better option. Ultimately, it's up to you to decide which blue cheese is the strongest. Try out different types and see which one you like best.
