Ah, but what liquid to use? The two classics are broth/stock, and wine. For many sauces, I prefer dry wine for a two reasons:
- You get the flavor of the wine, but most of the alcohol boils off.
- The small amount of alcohol that is left is a great flavor carrier. You know how sauces with oil in them tastes better, even if the oil itself doesn't have a flavor? That's because oil is a carrier of some flavors such as spices. Well, alcohol carries different flavors, so a little wine in a dish brings a lot of flavor.
