Because you don’t have to make your own crust, this gorgeous asparagus-striped tart is so easy it almost feels like cheating. But it’s not. It’s just simple yet stunning, effortlessly chic and company-ready. As there are so few ingredients in this recipe that each one makes an impact, be sure to buy a good all-butter brand of puff pastry. If you can manage to serve this tart warm, within an hour of baking, it will be at its absolute best, with crisp pastry that shatters into buttery bits when you bite down and still-runny cheese. But it’s also excellent a few hours later, should you want to get all your baking done before your guests arrive. If tarragon isn’t your favorite herb, you can use chives, basil or mint instead. And if you can manage to trim all the asparagus to the same length, this tart will be especially neat and orderly looking.
