You're right: recipes are, generally speaking, guidelines. However, there are certain recipes which are, let's call them, works of art, or so special that they deserve respect. Robuchon's quail with foie Gras; Marco Pierre White's Leek and Lobster Terrine; Adria's Red Mullet Gaudi - and even something as simple as Arrigo Cipriani's Carpaccio. I personally find it rather offensive that people think they can slap circles of almost anything on a plate, slather them with pesto, mayonnaise, chimichurri or whatever, enclose the plate in a jungle of watercress, sliced mushrooms, arugula, sundried tomatoes, microgreens, and then have the nerve to call the dish "carpaccio".
