Sugar is the most significant component of Irish coffee, and this ingredient is required for flavor and the creation of a fluffy floating cream. Most original Irish coffee recipes use a tablespoon of soft brown sugar, but newer versions utilize raw cane sugar or dark muscovado sugar. Dark muscovado sugar provides a toffee-like molasses flavor, but subtly seasoning molasses and flavored syrups can also be employed. Mixing them in a large basin is the best method to use them.
