Mastering the Five Mother Sauces
A professional kitchen functions on these five templates because they are reliable and adaptable. Once you understand the mechanics of the roux or the emulsion, you stop following directions and start building flavors based on what you have in the pantry.
Understand the starch and the heat
Most of these sauces require a roux, which is a simple paste of equal parts fat and flour. If you rush the cooking of the roux, your sauce will taste like raw flour; cook it until it smells like toasted nuts.
- heavy-bottomed saucepan
- whisk
- fine-mesh strainer
- double boiler
What goes in.
- 4 tbspunsalted butter
- 4 tbspall-purpose flour
- 2 cupsliquid (milk for Béchamel, stock for Velouté/Espagnole)
- 2egg yolks (for Hollandaise)
- 1 lbtomatoes, crushed (for Tomato sauce)
Controlling the Roux
Add your cold liquid gradually to the hot roux while whisking constantly. This prevents clumps and ensures a smooth, glossy consistency rather than a gritty paste.
The method.
Make the roux
Melt butter in a saucepan over medium-low heat. Whisk in flour and stir for 2-3 minutes until the foam subsides and the mixture smells toasted.
Hydrate the base
Add milk or stock in small splashes, whisking vigorously between each addition until fully incorporated. Simmer until the sauce coats the back of a spoon.
Finish the Hollandaise
Whisk yolks and lemon juice over a double boiler. Slowly drizzle in melted butter until the sauce holds a ribbon shape when you lift the whisk.
Strain
Pass every sauce through a fine-mesh strainer into a clean bowl to catch any stray bits of flour or egg.
Other turns to take.
Mornay
Stir Gruyère or Parmesan into Béchamel.
Béarnaise
Add tarragon and shallots to Hollandaise.
Demi-glace
Reduce Espagnole by half and combine with concentrated veal stock.
When it doesn't go to plan.
Keep your liquid warm when adding it to the roux to prevent the flour from seizing.
Never let the water in a double boiler touch the bottom of your Hollandaise bowl, or the eggs will scramble.
If your sauce develops a skin while sitting, place a piece of parchment paper directly on the surface.
The ones that keep coming up.
Why did my sauce clump?
Usually, the liquid was added too quickly or the heat was too high. Whisk harder, or pass it through a strainer to save it.
Can I use cornstarch instead of flour?
No. These sauces rely on the stable structure of a wheat-flour roux to hold up during long simmering or reheating.
