fruit tarts in Westchester
L'Elysee bakery in Pleasantville is making some terrific fruit tarts these days. They use high-quality fruit that was frozen when ripe, so the tarts are never slushy like so many others. Apricot, peach, fig, pear, apple... with or without a layer of almond pastry cream on the bottom. I like it best without--more fruit that way.
Croissants and brioches are pretty darn good, too, as are the cakes (esp chocolate ganache) and cookies. But avoid the baguettes.
146 Bedford Rd (right next to Michael's Tavern, diagonally across from Cafe Strega), 914-747-5660,
Try La Tulipe in Mt. Kisco. It's run by a young couple who make THE BEST croissant and brioche. The almond croissants are better than anything I've ever had anywhere, especially at 7:45 AM when they are just out of the oven. Compare the fruit pies, too! Sorry, don't know the address but it's in a little house at the intersection of Radio Circle and (I think) Lexington Avenue.
I second this endorsement. The pies are very expensive, but I recently threw a party and served their mixed berry pie (with the creme) for dessert and it got rave reviews.
Their pastries are good-- a bit uneven from my experience-- but good. But for croissants, I always try to make a trip to Mount Kisco. The bakery across the street from Hot Bagels on 117 (I've forgotten its name) has some of the most amazing croissants I've ever eaten anywhere. Go early because they run out by 9:30 or so.
