The shortcut the pros keep in the door of the fridge: demi-glace concentrate turning any pan's fond into a two-minute restaurant sauce.

Mise en place
Before you start
Yield: One skillet's worth
Prep checklist
Red Wine — or white — match your protein
In the post-sear pan: shallot in the fat 1 minute; wine scraped and reduced by half, 2–3.
Water + demi concentrate + thyme; simmer 2 minutes to a light glaze.
💡
Concentrate is triage, not cheating — it brings the gelatin and depth of hours in a teaspoon. Homemade demi (see the sauce library) remains the summit.
Cold butter mounted off-heat; season; pour over whatever earned it.
Taste before serving and adjust salt and acid — the last 30 seconds of seasoning matter more than any single ingredient.
Afterwards
Keep, reheat & pair
Storage
Airtight jar in the fridge, 3–5 days. Press plastic wrap onto the surface of starch-thickened sauces to stop a skin forming.
Freezing
Most sauces freeze 2–3 months; freeze in ice-cube trays for single portions. Emulsified butter/egg sauces don't freeze — they break on thawing.
Reheating
Reheat gently over low heat, whisking; butter- and egg-based sauces split when boiled. Loosen with a spoonful of warm water or stock.
Make ahead
Most sauces keep 3–5 days refrigerated and freeze in ice-cube trays for instant single portions. Emulsified butter sauces are best made within the hour.
