What is the secret to good souffle?

The secret to a good soufflé lies in the careful preparation of the base and the precise folding of beaten egg whites. Start with a well-flavored base, ensuring it's not too heavy, and allow it to cool slightly before incorporating the egg whites. When folding, be gentle to maintain the airiness, which is crucial for achieving that light, airy texture. Lastly, bake at the right temperature to ensure proper rising without burning.
