Building Silkier Sauces
The difference between a sauce that coats the back of a spoon and one that slides off the plate lies in the final moments of cooking. It is a game of patience and knowing when to pull the pan from the heat to keep the structure stable.
Control the heat, control the texture.
Avoid high heat once you begin the emulsification process, as excess heat destroys the suspension. Keep your butter cold and your liquid reduced before you begin.
- Stainless steel skillet
- Balloon whisk
- Fine-mesh strainer
What goes in.
- 2 tbspcold, unsalted butter, cubed
- 1/2 cupheavy cream or fortified stock
- 1 tspfresh herbs, finely minced
Monter au Beurre
This involves whisking cold, solid cubes of butter into a warm reduction off the heat. The cold fat creates a stable emulsion that thickens the liquid into a glossy coat.
The method.
Reduce the base
Simmer your stock or wine in a wide skillet until it is reduced by half; you want a concentrated, viscous liquid that tastes strong.
Remove from heat
Take the pan off the burner entirely. Adding butter while the pan is over a flame will melt the fat instantly rather than emulsifying it.
Incorporate the fat
Drop in one cube of cold butter and whisk vigorously. Once it disappears into the liquid, add the next cube. Repeat until the sauce turns opaque and velvety.
Finish and serve
Check the consistency by dipping a spoon in; the back should be coated evenly with no streaks of separated oil. Serve immediately.
Other turns to take.
Starch-thickened
Whisk a teaspoon of cornstarch into cold water before stirring into a simmering pan to create a translucent, gel-like sheen.
Protein-rich
Whisk in a single egg yolk mixed with a little warm liquid to create a thick, custard-like texture, common in classic carbonara.
When it doesn't go to plan.
Always use cold butter; the temperature contrast is necessary for the emulsion to hold.
If the sauce breaks and looks greasy, add a tablespoon of cold water or cream and whisk rapidly off-heat to pull it back together.
Strain your sauce through a fine-mesh sieve if you used shallots or garlic in the reduction to ensure a smooth mouthfeel.
The ones that keep coming up.
Why does my sauce look oily?
The sauce got too hot, or you added the fat too quickly. Take the pan off the heat and whisk in a small splash of cold liquid to re-emulsify.
Can I use margarine?
No. You need the milk solids and pure fat content found in high-quality unsalted butter to provide the proper structure for the sauce.
