Storage: Store the assembled cake covered in the refrigerator for up to 2 days. The cake is best served chilled.
Substitutions: If you prefer a non-alcoholic version, substitute the dry sherry with an equal amount of grape juice or additional water with a splash of lemon juice.
Tip: For the smoothest coulis, always strain the berry mixture through a fine-mesh sieve to remove seeds.
Variations: You can use store-bought Angel Food cake to save time, but homemade yields a lighter texture.
