Ingredients:
- Whole Milk 500 ml Must be whole milk for richness.
- Unsalted Butter approx. 50 g For the Roux
- All-Purpose Flour approx. 50 g For the Roux
- Onion 1 half
- Bay Leaf 1 piece
- Whole Cloves 2-3
- Salt 1 Pinch
- White Pepper 1 Pinch
- Nutmeg Pinch Freshly grated is best.
Method
Step 1: The Infusion (The Secret Step)
- Take your half onion and place the bay leaf against the flat side.
- Use the cloves like "nails" to pin the bay leaf into the onion. This is your Oignon Piqué.
- Place the milk and the studded onion into a saucepan.
- Gently bring the milk to a simmer (just before it starts to boil).
- Turn off the heat, cover the pan, and let it sit for 10–15 minutes. This lets the onion and spices infuse like tea.
- Remove the onion and discard it. Your milk is now seasoned.
Step 2: The Roux
- In a separate clean saucepan, melt the 50g of butter over medium-low heat.
- Add the 50 g of flour and whisk constantly for about 2 minutes. You want to cook out the "raw" flour taste, but don't let it turn brown. It should stay a pale golden color.
Step 3: Combine
- Gradually pour the infused milk into the roux, a little bit at a time.
- Whisk vigorously after each addition to ensure there are no lumps.
- Once all the milk is in, keep whisking until the sauce comes to a gentle simmer and thickens into a velvety consistency.
- Add your salt, pepper, and a final grating of nutmeg.
Why do it this way?
By pinning the bay leaf and cloves to the onion, you create a "flavor bomb" that is incredibly easy to remove. It saves you from fishing out individual cloves or straining the sauce through a sieve at the end.
