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, Laura Calder, Michael Smith, Anna Olson, 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 a baker, buy a scale! 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.
