Œufs Mayonnaise "Vapeur"
(uhf mah-yoh-nez vah-puhr)
Chapter 1 — Apéro & Hors d'Œuvres
The true measure of a French bistro isn't the complexity of its sauces, but the perfection of its simplest dishes. The œuf mayonnaise is an exercise in profound culinary restraint: an egg cooked to the exact second where the white is tender but the yolk remains a translucent, fudgy marvel, draped in a hand-whisked, mustard-laced emulsion. To achieve this standard in the American home kitchen, we don't boil our eggs; we steam them, a technique that violently shocks the albumen to guarantee flawless peeling every time. When you slice these in half and scatter them with chives, your kitchen will smell exactly like Spring Street at 1:00 PM on a Friday.
Before you start
The mayonnaise requires time for the vinegar and mustard to marry with the fat.
At minimum, chill the finished mayonnaise for one hour, but ideally, let it rest in the refrigerator overnight before serving for the absolute best depth of flavor.
Ingredients
- eggs6 large
- ice4 cup
- egg yolks2 large
- smooth Dijon mustard1 tbsp
- whole-grain mustard1 tsp
- Champagne vinegar1 tbsp
- fine sea salt1/2 tsp
- black pepper1/4 tsp
- neutral oil1 cup
- boiling hot water1 tbsp
- fresh chives2 tbsp
- flaky sea salt1/2 tsp
- crusty baguette1/2 large
Method
- 01
Set up a steamer basket inside a large pot over one inch of aggressively boiling water.
While the water heats, prepare a large ice bath; this is the emergency brake that halts the cooking process and prevents the tragic green ring of overcooked yolks.
- 02
Lower the cold eggs into the steamer basket, cover tightly, and steam for exactly 8 minutes and 40 seconds.
This highly specific timing ensures a yolk that is perfectly set but meltingly creamy at its core. When the timer sounds, immediately submerge the eggs in the ice bath for at least 15 minutes.
- 03
Whisk the egg yolks, both mustards, half a tablespoon of vinegar, fine sea salt, and black pepper in a heavy bowl for thirty seconds.
The golden rule of authentic mayonnaise is that salt cannot dissolve in oil. Whisking the salt into the water-phase ingredients first ensures it dissolves completely, curing the yolks and establishing the base for your emulsion.
- 04
Whisking constantly and confidently, begin adding the neutral oil a literal drop at a time until the mixture thickens and turns pale yellow.
Do not rush this, or the oil will overwhelm the water phase and break into a greasy puddle. Once you have incorporated a quarter cup drop-by-drop and the emulsion is stable, pour the remaining oil in a very slow, thin, steady stream while whisking vigorously.
- 05
Heat the remaining half tablespoon of vinegar and the boiling water together, then whisk this hot liquid into the finished mayonnaise.
The heat slightly cooks the proteins, tightening and stabilizing the emulsion while lightening its color to achieve the perfect draping texture.
- 06
Gently tap the chilled eggs to crackle their shells, peel them, and slice exactly in half lengthwise.
Because they were steamed, the shells will slip off effortlessly. Wipe your knife with a damp cloth between cuts to ensure pristine edges.
- 07
Arrange three halves per person on cold plates, season the yolks with flaky salt, and generously spoon the mayonnaise over the top.
Do not pipe the mayonnaise; it should thickly coat the egg and pool slightly onto the plate. Shower with chives and serve immediately alongside the baguette to wipe the plate clean.
Notes
If your whisking arm falters and the mayonnaise breaks into a greasy puddle, do not panic.
Place one teaspoon of hot water in a clean bowl, and slowly whisk your broken mayonnaise into the hot water, drop by drop, until the emulsion miraculously re-forms.
Never use extra virgin olive oil for a brasserie mayonnaise.
The violent mechanical action of whisking shears the polyphenol compounds in olive oil, releasing a profoundly bitter taste. Stick to grapeseed, sunflower, or canola oil.
