Fun is the most important. If you do stuff for money, it never works out.
I try to greet my friends with a drink in my hand, a warm smile on my face, and great music in the background, because that's what gets a dinner party off to a fun start.
The most important thing for having a party is that the hostess is having fun. I'm very organized. I make a plan for absolutely everything. I never have anything that has to be cooked while the guests are there. The only thing I might have to do is take something out of the oven and carve it.
I worked for the Office of Management and Budget in the White House, on nuclear energy policy. But I decided it would be much more fun to have a specialty food store, so I left Washington D.C. and moved to the Hamptons. And how glad I am that I did!
People have more fun if they don't eat so much they have to be taken home in an ambulance.
If it's a cocktail party, I generally make five or six different things, and I try to choose recipes that feel like a meal: a chicken thing, a fish or shrimp thing, maybe two vegetable things, and I think it's fun to end the cocktail party with a sweet thing.
