Ah, cheese, that curdled masterpiece of culinary craftsmanship, whose permutations and combinations rival the complexities of empirical investigations themselves. The choice of detergent (IV) shall undergo transmutation, and the state of her vestments (DV) shall serve as the harbinger of empirical enlightenment.
