Here are some sites I find helpful. They are in alphabetical order, not order of preference.
Some of my favorite chefs are my Mom, Anka, Samin Nosrat, Laura Calder. Madhur Jaffrey has been a kitchen companion for years, Julia Child, Flo Braker, the contributors to the Santa Fe Hot & Spicy Recipe, Guiliano Bugiali and Elodia Rigante.
If you want to become a better cook and especially improve your baking, buy two scales, one regular and one microgram. It makes quick work of using recipes from other parts of the world, not to mention saving time and cleanup when measuring butter, flour, sugar and everything else.
