Do you have to use espresso coffee for tiramisu?

Here's why:

* Flavor: Espresso has a strong, rich flavor that complements the sweetness of the mascarpone cheese and the bitterness of the cocoa powder.

* Intensity: The caffeine in espresso provides a kick that balances the creamy texture of tiramisu.

* Soaking: Espresso's intensity allows it to properly soak into the ladyfingers without becoming overly soggy.

However, you can substitute espresso with other options:

* Strong brewed coffee: This will give you a milder coffee flavor.

* Instant coffee: While not ideal, it can be used in a pinch.

* Coffee liqueur: Liqueurs like Kahlua or Tia Maria can add a boozy and coffee-flavored kick.

Ultimately, the choice is yours based on your preference and what you have available. Experiment and find what you enjoy most!
