Storage: Tiramisu must be kept refrigerated. It is best consumed within 2-3 days.
Substitutions: If you prefer a non-alcoholic version, you can omit the Marsala/brandy and use additional strong coffee or a splash of vanilla extract for the dipping liquid and zabaglione.
Tips: Ensure the mascarpone is at room temperature before mixing to avoid lumps. Do not over-soak the ladyfingers, or the dessert will become too wet.
Variations: Dust the top with cocoa powder or grated dark chocolate just before serving for extra richness.
