Would you mind sharing what you used to learn cooking? My main struggle is recipe books that teach you the recipe rather than cooking. But I'd love to learn HOW to cook, not WHAT to cook.
I disagree with the J. Kenji Lopez-Alt suggestions. He is too extreme/OCD for beginners. A much more accessible source is Harold McGee who wrote "On Food and Cooking - The Science and Lore of the Kitchen". McGee reviews the science but also some history. He also reviews some of the cooking tips your mom gave you and why they work or don't work.
For beginners I'd instead recommend his book Keys to Good Cooking. It takes all the information in On Food and Cooking and distills it down to the practical lessons a cook will need to improve their cooking.
