...classic recipe books by famous cooks (Bocuse, Escoffier, Artusi, ...) are cheap, often available in the public domain or at bargain shops. Reading and learning from these works is the best thing you can do. I personally recommend Bocuse's recipe book. Cooking is mostly about finding the right ingredients at the right time. Neither the youtuber living on the other emisphere nor AI can know about what is available at your local market (and I underline *market*, not supermarket, Amazon Fresh, or so).
