Is this an advertisement for a 5-cookbook set at $625? If I were a beginner, I would spend that money on a carbon steel pan, one Staub pot, a good kitchen and paring knife, one peeler, and I’d have some left for high-quality ingredients to experiment with myself. If I were more advanced, I would look into professional culinary institutes’ books. Everything in between is easily accessible on YouTube. An expensive book as beautiful as it is will never make a good cook; only good tools, ingredients, and practice will do.
