Star Kitchen: Jessica Seinfeld

When cookbook author Jessica Seinfeld, her husband, Jerry, and their three kids head to their East Hampton, N.Y., estate for the summer, their entire social universe travels with them. "My parents stay here, and all my friends — sometimes for the whole summer," Jessica says. "There are always 10 kids around." When you have a sprawling estate with a three-bedroom guesthouse, finding space for everyone isn't a problem. Feeding them all, however, can be tricky, so she keeps giant jars of potato chips and bagels on the counter of this guesthouse kitchen, and she sets out buffets on an old farm table so guests can eat on their own schedule.

Her guesthouse looks centuries old, but it was built just 10 years ago. Jessica wanted it to feel like the 18th-century Long Island house she grew up in, so she chose elements that feel rustic and worn, like unfinished pine floors with mismatched planks.

Jessica installed open shelving so guests can help themselves to whatever they need. "Everyone knows where everything is because they can see it all," she says.

Knowing she would be spending a lot of time in this kitchen, Jessica wanted to make the space feel light and airy. She created the paint color — a mix of blue and gray — to look like the sky.
