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.
The closest of that for me would be GialloZafferano. However I usually websearch multiple recipes for the same dish, to get a good idea on variation, so I don’t usually rely on a single website or chef.
