The most concentrated form of veal jus, reduced until it sets like jelly on cooling. A spoonful of demi-glace lifts any sauce a level; it is the reason restaurant sauces taste different from those at home.

Method
Reduce the aromatics
Bring the wine to the boil with the shallot, thyme and bay leaf in a large pan and reduce to a syrupy residue of about two tablespoons.
Reduce
Add the veal jus and reduce over a moderate heat to roughly a quarter of the volume. Skim off the scum in between. Allow one and a half to two hours; don't force it over a high heat, or it will turn bitter.
Test
Dip a spoon in the sauce and draw a line across the back with your finger. If it stays, it is ready. A drop on a cold plate should set within a minute.
Strain and finish
Pass through a fine sieve, only now season with salt and, if you like, finish with cold butter for gloss.
Tips & notes
Demi-glace freezes very well. Pour it into ice-cube trays; one cube in a pan with browned bits, a splash of wine and a knob of butter becomes a complete sauce within five minutes. Never salt before reducing; the concentration does the rest.
