The white mother sauce: milk thickened with a blond roux. The base of mac & cheese, lasagna, croque monsieur, and every gratin you've ever loved. Ratio to memorize: 1:1:10 — butter, flour, milk by weight.
Codified by Escoffier as one of the five mother sauces — the foundations from which hundreds of classical sauces descend.

Prep checklist
Milk — warm
Nutmeg — freshly grated
3 steps
Method
1
Melt the butter over medium heat, add the flour, and whisk 2 minutes until it smells like baked pastry but takes no color — this is a blond roux.
2 min — timer available in cooking mode
Why this works
The 2 minutes cooks out the raw flour taste. Rushing this is why homemade white sauce sometimes tastes like paste.
2
Add the warm milk in three additions, whisking each fully smooth before the next. It will seize, then loosen — keep whisking.
Why this works
Warm milk + gradual additions = no lumps, ever.
3
Add bay and simmer gently 8–10 minutes, stirring the bottom, until it coats a spoon thickly. Season with salt, white pepper, and nutmeg.

Chef's notes
Taste before serving and adjust salt and acid — the last 30 seconds of seasoning matter more than any single ingredient.
When it goes sideways
Common mistakes
Lumps
The liquid went in too fast or too cold. Whisk hard; if lumps persist, pass the finished sauce through a fine sieve — no one will ever know.
Tastes like flour
The roux needed another minute of cooking before the liquid. Simmer the finished sauce 5 extra minutes and the raw edge cooks out.
A skin formed
Press plastic wrap or buttered parchment directly onto the surface while it holds.
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.

Questions
Why white pepper?
Pure vanity, honorable vanity: black specks show in a white sauce. The flavor difference is minor; the tradition is strong.
