Everything I know about getting a party started right, I learned at Houston's restaurant in Atlanta. No kidding. Its creamy, bubbling spinach and artichoke dip was a must on date night in high school, and these days it's the dish that even the snobbiest of food snobs can't resist. I'll whip it up for friends and, no matter what else I serve, it's always the first thing to go. Sometimes I leave out the spinach, add red pepper flakes, or use whatever vegetable is in season. In other words, it stands up to improvisation. We've put a spring spin on the dish, starring asparagus, just-dug-up leeks, sweet peas, and fresh goat cheese. Serve it with crostini, tortilla chips, or crudités. Or just eat it by the spoonful. It's that good. —Andrew Knowlton
