I usually start with Food Wishes, Serious Eats, or the New York Times. Julia Child for French food, Just One Cookbook for Japanese food. Budget Bytes when the bank account is looking a little thin. Dessert Person when I have a lot of time and want to knock the socks off my friends.
I like JustOneCookbook for Japanese food. Most of the ingredients on her recipes are easily available. I’ve tried her recipes and they taste good. She also has recipes for ingredients that aren’t easily available so you can make your own.
