A Demi-glace (or demi-glaze) is a brown sauce that is rich, concentrated and deeply flavorful. It is traditionally served with red meats.
Olives bring the flavor to this dish to a whole new level. The only difference between green olives and black olives is ripeness. Unripe olives are green, whereas fully ripe olives are black (green olives must be soaked in a lye solution before brining–this preserves their color, whereas ripe black olives can proceed straight to bribing). Spanish olives are called for in this recipe, however it is really up to your personal preference.
Here are the different types of olives available for you to choose from:
- Manzanilla: Spanish green olive, lightly lye-cured then packed in salt and lactic acid brine
- Picholine: French green olive, salt-brine cured
- Kalamata: Greek black olive, harvested fully ripe, almond-shaped, brine-cured
- Niçoise: French black olive, harvested fully ripe, small in size
- Liguria: Italian black olive, salt-brine cured
- Ponentine: Italian black olive, salt-brine cured, packed in vinegar
- Gaeta: Italian black olive, dry-salt cured, then rubbed with oil, wrinkly in appearance
- Lugano: Italian black olive, very salty
- Sevillano: Californian, salt-brine cured, preserved with lactic acid
