Clear half Glaze

This demi-glaze must not be confused with demi-glaze sauce. The demi-glaze is not a sauce but simply good, clarified gelatinous gravy reduced to half the consistency of a glaze; which means only slightly thickened; it must be bright, clear, and succulent. Before taking it from the fire mix in with it a spoonful of Madeira wine for each two quarts of liquid.
