Eggs à la Tripe, Bourgeoise

Ingredients

Equipment Needed

• •2-quart (1.9-liter) heavy saucepan with lid
• •2-cup (475 ml) microwave-safe heatproof jug or small saucepan
• •6- to 8-inch (15- to 20-cm) fine-mesh sieve and flexible spatula
• •1-quart (950 ml) round serving bowl or timbale

Instructions

1. 1

   Hard-cook the eggs

   Set the eggs in a medium saucepan in one layer and cover them by 1 inch (2.5 cm) with cold water. Bring just to a boil over medium heat, cover, remove from the heat, and leave for 11 minutes. Transfer the eggs to cold water for 5 minutes, then peel them and keep them whole while the sauce cooks. The yolks should be completely set and golden, not ringed with green; cooling stops the cooking before that ring forms.

2. 2

   Stew onions without color

   Wipe the same saucepan dry and melt the butter over low heat. Add the chopped onions and ¼ teaspoon of the salt, cover, and stew gently for 10 to 12 minutes, stirring often, until the onions are completely soft and translucent but show no brown edges. If they begin to color, pull the pan from the heat and stir in 1 tablespoon from the measured milk, then return the pan over lower heat. Ça se rattrape if you catch it early; once the onions are deeply browned, the ivory finish cannot be restored.

   The onions must soften rather than fry. Listen to the pan: a quiet hiss is right, while loud sizzling means the heat is too high.
3. 3

   Bind with flour

   Heat the milk in a microwave-safe jug or small saucepan until it just reaches the boil. Sprinkle the flour evenly over the softened onions and stir over low heat for 2 minutes. This roux blanc (white roux) must lose its raw flour smell without taking color. Add the very hot milk in three additions, whisking each addition smooth before pouring the next, then season with the remaining salt, the white pepper, and nutmeg. If the milk went in too quickly and the roux formed beads, lift the pan from the heat and whisk firmly; the final sieve will catch any stubborn lumps.

4. 4

   Simmer twenty minutes

   Bring the sauce to the gentlest simmer and cook uncovered for the full 20 minutes, stirring across the pan floor every 2 or 3 minutes. It should give only lazy bubbles while the onions collapse and the raw edge leaves the flour. If it tightens enough to hold a trench behind the spoon, add boiling water a tablespoon at a time to replace what evaporated. If the milk catches on the bottom, do not scrape it up; pour the clean upper sauce into the heatproof jug, rinse the saucepan, and continue over lower heat.

5. 5

   Sieve and reheat

   Set a fine-mesh sieve over the heatproof jug and pour in the sauce. Rub it through firmly with a flexible spatula, pressing until only dry onion fibers remain; do not merely strain away the onions, because the pulp passing through the mesh gives the sauce its body. Rinse the saucepan, return the sieved sauce to it, and reheat over medium-low heat until very hot, glossy, and just bubbling at the edge. If it is too thick to pour generously, whisk in a teaspoon of boiling water; if too thin, simmer it for another minute. Taste and correct the seasoning.

6. 6

   Quarter and cover

   Warm a 1-quart (950 ml) round serving bowl or timbale with hot water, then empty and dry it. Quarter the eggs lengthwise and arrange them snugly in the warm dish, yolk sides showing. Pour the onion sauce over them at once, covering every quarter while the sauce is very hot. Serve immediately; the sauce warms the eggs without simmering their whites into rubber. À table!

Chef Tips

• •Plain yellow onions are right here. Sweet onions become sugary and lack the savory backbone this milk sauce needs; red onions spoil its pale color before the pan is even warm.
• •The source leaves the butter to the cook's judgment. Two tablespoons is the practical measure for this scaled pan, enough to sheath the onions while they soften without leaving the finished sauce greasy. Butter, not margarine.
• •Use whole milk, not cream. The sauce is deliberately milk-based, light enough to pour around the eggs and thickened by the roux and sieved onion pulp; cream would smother that balance.
• •Do not replace the fine sieve with a blender. A blender can whip air into the milk sauce, while rubbing through the mesh gives the quiet, close texture that marks the bourgeoise finish.
• •Bring toasted country bread to the table. The sauce is generous by design, and leaving it in the bottom of the dish would be very poor judgment.

Advance Preparation

• •The eggs can be hard-cooked up to 2 days ahead and refrigerated in their shells. Peel and quarter them only when the sauce is nearly ready so the cut yolks do not dry.
• •The onion sauce can be cooked, sieved, and chilled 1 day ahead. Cover its surface directly before refrigerating, then reheat gently and whisk in 1 or 2 teaspoons of boiling water if it has tightened.
• •Do not assemble the finished dish ahead. The very hot sauce poured over newly quartered eggs is part of the method, warming them without further cooking.
