"Like most pastry chefs, I endlessly test a recipe to get it exactly how I want it. But every now and then, Iâ??m reminded that perfection can be a function of too many interrelated variables. Who says that a single recipe will work perfectly for every cook in every oven on any given day? Some recipes need to be practiced and perfected in oneâ??s own kitchenâ??what works in someone elseâ??s may not work the same in yours. Fortunately, these chocolate éclairs are perfectly imperfectâ??that is, they are exquisitely delicious, even as works in progress!
