One of my favorite sites with lots of nice recipes is Martha Stewart. Here you will find lots of inspiration to do both cooking and simple tips and tricks.
If you have not yet heard of Donna Hay from Australia, then you must check out here website.
My swedish favorite is Leila Lindholm who is fantastic, a very colorful person.
And another one of my favorites is of course Nigella. But i always wonder how Nigella works in the kitchen without using any apron and always looks so radiant.
