Glace de Viande
Meat stock reduced to a concentrated glaze. Think sauce concentrate, not a beverage challenge.
Ingredients
- 2 litres unsalted, gelatin-rich brown beef or veal stock
Measures: 1 tbsp = 15 ml; 1 tsp = 5 ml. Yields are approximate. Pan width and heat affect reduction time; the texture gets the final vote.
Method
Check the stock
Use strained, defatted stock with good flavor and no added salt. Commercial salted broth is not a suitable input. Stock-making time is additional.
Reduce
Simmer uncovered in a wide heavy saucepan, skimming foam. As the volume drops, transfer to a smaller pan so the edges do not scorch.
Slow down
At roughly 250 ml, reduce the heat and stir frequently. Stop when glossy and syrupy, usually 150–250 ml total. It will become much firmer when cold.
Portion
Pour into small shallow containers to cool promptly. Refrigerate or freeze in small portions; label the date and starting stock.
Checkpoint: Hot glaze clings strongly to a spoon; chilled glaze is firm. Final volume varies with the original stock.
Failure modes and fixes
Too thick: loosen with water. Scorched: discard the burnt portion without scraping. If the whole batch tastes burnt, there is no graceful rollback.
More rescue techniques →Put it to work
Whisk 1–2 tsp into a pan sauce or loosen with unsalted stock. This is concentrated seasoning and body, not a full ladle per plate.
Storage and reheating
Cool promptly in shallow containers and refrigerate within 2 hours (1 hour above 90°F / 32°C). Keep at 40°F / 4°C or colder for 3–4 days, or freeze in portions. Bring reheated cooked sauces to a rolling boil; for butter-finished sauces, ideally store the base and add fresh butter after reheating. Cream sauces may separate after freezing.
