Apple Sauce
Sauce aux pommes turns four plain ingredients into a softly cinnamon-scented companion for roast duck, goose, or hare. Covered gentle cooking is the whole technique: let the apples slump in their juices, then whisk.

Sauce aux œufs au beurre fondu teaches a small but useful truth: a sauce need not be thickened to feel complete. Here the butter stays fluid, lemon gives it a clean edge, and hot egg provides the substance. Know this before you touch a pan: the eggs must stay in bold cubes. Stir them into crumbs and the sauce loses its generous character.
The old service assumed a saucier at the stove, œufs durs, hard-boiled eggs, held hot, and chopped parsley already scalded before the order arrived. A stockpot never off the fire and a salamander served many classical sauces, but this entry calls on neither. At home, one saucepan does the work, and the egg water scalds the parsley before becoming a gentle water bath. The source's quarter-pound of butter and three eggs already make a sensible quantity for four, so its ratio and sequence remain intact; only the measurements and timing have been clarified. One cook, one stove, one evening.
When it is right, the butter gleams around distinct pieces of ivory white and yellow yolk, with green parsley scattered through and lemon cutting the richness cleanly. The fold is the step that matters most: roll the pan gently, keep the heat low, and never beat the eggs into the sauce.
Sauce aux œufs au beurre fondu belongs to the cuisine bourgeoise table and the national classical sauce repertory, not to one French province; it was served warm with poached fish, boiled vegetables, and potatoes. Its place beside the emulsified butter sauces can mislead: it is deliberately not a hollandaise, because the butter remains simply melted and the œufs durs supply texture rather than thickening. The grand kitchen gave this economical household combination a formal place in service without disguising its simplicity.
The technique, the tradition, and the story behind every dish.

Instructions

Cook the eggs
Put the eggs in a small saucepan and cover them with cold water by 1 inch (2.5 cm). Bring just to the boil, lower the heat to a gentle simmer, and cook for 10 minutes. Cool them under running water only until they can be handled, then peel while still warm. Cut each egg into bold ¾-inch (2 cm) cubes and keep them covered in a warm bowl. Small dice will crumble when folded, so resist the little knife work; the large pieces are the dish.
A faint grey rim around an overcooked yolk is not handsome, but it does not ruin the sauce. Never apologize at your own table. Cut the eggs generously and carry on. - 2
Scald the parsley
Return the egg water to the boil. Put the chopped parsley in a fine-mesh sieve, lower it into the water for 10 seconds, then lift it out and press it thoroughly dry with the back of a spoon. Scalding softens the parsley's raw edge without turning it to paste. Reserve a bowlful of the hot water for the finishing water bath, then empty and dry the saucepan completely.

Melt without coloring
Melt the butter in the dry saucepan over the lowest heat. When only a few small pieces remain, lift the pan from the heat and swirl until they disappear; the butter must be fluid and golden, never toasted. Stir in the salt, pepper, and lemon juice in that order. The lemon may gather in tiny beads because this is melted butter, not an emulsion. That loose appearance is correct. If tan milk solids begin to catch, pour the clear butter immediately into a clean bowl, leaving the specks behind, wipe the pan, and return the butter. Ça se rattrape. If the whole pan has taken on a nutty aroma, begin again because the sauce's character has changed.

Fold, never stir
Add the warm egg cubes and scalded parsley to the seasoned butter. Roll the pan gently from the wrist to coat them, using a spoon for one careful fold only if a few pieces remain bare. Warm over the lowest heat for 30 to 60 seconds without simmering. If cool eggs make the butter cloudy or cause it to begin setting, place the saucepan in the reserved hot water and roll it gently until the butter becomes fluid and glossy again. Ça se rattrape. Do not whisk, mash, or chase the cubes around the pan.

Serve at once
Taste and correct the salt, then transfer the sauce to a warmed sauceboat. Spoon it generously over poached white fish, boiled leeks, asparagus, cauliflower, or new potatoes while the butter is fluid and the eggs are hot. Serve within 10 minutes. Cooking well is not cooking fancy. À table!
Chef Tips
- •Use fresh unsalted butter. There is no roux, stock, or reduction to hide a tired flavour, so the butter carries everything. Butter, not margarine.
- •Cut the eggs into pieces about the width of your thumb. The whites should hold clean edges and the yolks should remain mostly inside their cubes; chopped egg would make a different sauce.
- •Scald the parsley only briefly and press it dry. Wet parsley spits when it meets butter and leaves the finished sauce watery around the edges.
- •This quantity gives roughly ¼ cup (60 ml) per person, enough to coat a piece of poached fish or a generous serving of vegetables without burying it.
Advance Preparation
- •The eggs may be hard-boiled one day ahead and chilled in their shells. Before making the sauce, peel them and warm them whole for 3 minutes in hot, barely simmering water, then dry and cut them into large cubes.
- •The parsley may be chopped and scalded up to 2 hours ahead. Press it dry, cover it, and let it lose its chill before adding it to the butter.
- •Do not make the assembled sauce far ahead. If service is delayed, hold the covered saucepan in warm water for no more than 10 minutes and roll it gently before serving; direct heat will fry the egg edges.
