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’ma fan of Minimalist Baker. They specialize in meals with a limited number of ingredients that can be made in 30 minutes or less, often with only one bowl. They include meals for both vegans and people who like meat.
