Grand Marnier Souffle with Shaved Chocolate

From America's Test Kitchen

Home cooks are wary of attempting soufflés, which have the reputation of being difficult and temperamental and so are relegated to being eaten only in restaurants. The reality, however, is that they are relatively easy to make. To prove the point, we set out to develop a reliable recipe for a classic Grand Marnier soufflé.

The best soufflés have a crusty top layer above the rim of the dish and a contrasting rich, creamy, almost-fluid center, so we needed to produce height without making the entire dish foamy. For the base we began with a bouillie—a paste of flour and milk. Butter kept the egginess at bay, and increasing the usual amount of flour prevented the frothiness we wanted to avoid. An equal number of egg whites and yolks was the right proportion for rise versus richness. Adding a little sugar and some cream of tartar to the whites while we whipped them stabilized the whites so that they would hold their structure. We discovered that the sugar must be added gradually and partway through the beating process, not at the beginning, or the soufflé will not rise properly and will taste too sweet. We also found it important to remove the soufflé from the oven while the center was still loose and moist to prevent overcooking. With a luxuriously creamy interior and crusty top, our foolproof soufflé is an impressive dessert that can easily be made at home.
