Lombardo Marsala 421 is a concentrated version of imported Marsala wine. One bottle of 421 is equivalent to 4 bottles of traditional Imported Marsala and even more of Domestic Marsala. Lombardo Marsala 421 is used when making a multipurpose Marsala Sauce that is served over Chicken, Veal, Steak, and other restaurant dishes. Lombardo Marsala 421 will significantly lower a restaurants cost per dish. Lombardo Marsala 421 is already partially reduced so cooking time is greatly reduced which means less time on a gas burner. If you make a general purpose Marsala Sauce now, you would prepare it the same way but use ¼ less Imported Marsala wine. If more liquid is desired you can add water or even better, white wine.
