Mastering the Reduction
This is how you turn a watery pan sauce into something that clings to the back of a spoon. It is the most reliable way to build intensity in a dish using nothing but heat and patience.
Control the surface area to control the speed.
The wider your pan, the faster the liquid evaporates. Use a wide skillet for a quick finish or a small saucepan if you want a slow, controlled thickening.
- wide stainless steel skillet
- silicone spatula
- tongs
What goes in.
- 1.5 cupsdry red or white wine
- 1 cuphigh-quality beef or chicken stock
- 1 tbspcold unsalted butter, cubed
How to know when it is finished
Dip a metal spoon into the liquid and pull it out. Run your finger across the back of the spoon; if the line stays clean and the liquid does not run back into the path, the reduction is ready.
The method.
Deglaze the pan
After searing your protein, pour the wine into the hot pan. Use your spatula to scrape every browned bit from the bottom.
Simmer
Bring the liquid to a steady simmer over medium-high heat. Do not boil it violently, as this can make the edges bitter.
Reduce by half
Keep the liquid moving. Once it reaches a syrupy consistency and reduces by roughly half, add your stock.
Finish with butter
Remove the pan from the heat. Whisk in the cold cubes of butter one by one. This emulsifies the sauce, giving it a glossy, velvet finish.
Other turns to take.
Balsamic Reduction
Simmer balsamic vinegar until it coats the back of a spoon; drizzle over grilled vegetables or caprese.
Citrus Reduction
Reduce fresh orange or lemon juice with a pinch of sugar to create a sharp glaze for roasted poultry.
When it doesn't go to plan.
Always use a non-reactive pan like stainless steel; aluminum can impart a metallic tang to acidic reductions.
Be wary of salt. Since reduction concentrates everything, it also concentrates salt. Taste only after the final reduction is complete.
If the sauce breaks or looks oily, whisk in a teaspoon of warm water to bring it back together.
The ones that keep coming up.
Can I speed up the process by cranking the heat?
High heat causes the sugars to caramelize too quickly, which often results in a burnt or bitter taste. A steady, medium-high simmer is faster and more reliable.
