Marsala is a wine, dry or sweet, produced in the region surrounding the Italian city of Marsala in Sicily. Marsala first received Denominazione di Origine Controllata (DOC) status in 1969.
If you anticipate making a recipe that calls for Marsala wine, you can make a mushroom flavored base ahead of time. No matter what, you are never really going to replace the flavor effect created by actual Marsala wine. But, you can achieve a bit of the aromatic mushroomy effect of the Marsala.
