Spinach and Gruyère Soufflé
Serves 8.
Note: Soufflés aren't hard; they simply require that you beat the egg whites to lofty peaks, then fold them in. An electric mixer or stand mixer is best for this, although you can do it by hand if you have a strong arm. To fold, plop the beaten egg whites on top of the béchamel, sink your spatula into the center, and then pull it toward you along the bottom and up the side of the bowl. Turn the bowl slightly and repeat, moving the spatula in a series of circles to mix the egg whites in gently, without deflating them. When there are just few wispy trails of egg white visible, portion into your baking dishes. From Robin Asbell.
