Food Recipes Tomato Tart With Mustard Créme Fraîche 5.0 (1) Add your rating & review This gorgeous tart is deceptively simple. Just roll the puff pastry, spread with mustard-spiked crème fraiche, and shingle sliced tomatoes overtop. Then, bake the pastry until it’s golden brown, that’s the key to a flaky (not soggy) crust. Looking for a fun project? You can create a rainbow ombre effect that’s perfect for Instagram. Start with a red tomato at the top, then segue into a yellow tomato, and finish with a green one on the bottom. If you can’t find crème fraiche, sour cream works equally well.
