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 à l’Écossaise (Scotch egg sauce) teaches the white roux in its plainest, most useful form. The one true thing to know before you touch the pan is this: cook the flour in the butter before the milk arrives. Pale does not mean raw. Give the roux its few quiet minutes and the finished sauce will taste of milk, butter, nutmeg, and egg, never flour paste.
The source formula assumed a saucier beside a second pan of boiling milk, with enough boiled haddock or cod moving through service to justify the quantity. Your honest equivalent is one heavy saucepan, a smaller pan for the milk, and a whisk. No stockpot or salamander belongs here. This version is expanded only to meet the requested two-quart yield, with the butter-flour-milk ratio and three-eggs-per-pint proportion intact. The separate sauce station is scaffolding, but the white roux and its full ten-minute simmer are the dish. One cook, one stove, one evening.
When it is right, the Sauce aux Œufs à l’Écossaise is ivory and softly spoon-coating, with warm cubes of white and yolk held throughout rather than mashed into it. The moment that matters is the milk meeting the roux: add it in measured pours and whisk into the corners. If it lumps, don't panic. Ça se rattrape, and the method tells you exactly how.
Sauce aux Œufs à l’Écossaise belongs to the Anglo-French fish table, where French white-roux technique met the British practice of serving boiled haddock and cod with a mild milk-and-egg sauce. Its Scotch name points toward that fish service, especially haddock, not toward the sausage-wrapped fried egg that shares the name in English. The classical repertoire kept the sauce deliberately quiet so it could soften salt cod and enrich fresh fish without concealing either.
The technique, the tradition, and the story behind every dish.

- •3-quart (2.8-liter) saucepan for heating milk
- •Large saucepan with lid for the eggs
- •Balloon whisk
- •Fine-mesh sieve
Instructions
- 1
Cook and dice eggs
Cover the eggs with cold water by 2.5 cm, bring the water just to the boil, then cover the pan and remove it from the heat. Leave the eggs for 11 minutes. Drain and cool them under running water only until they can be handled, then peel and cut both whites and yolks into neat 1 cm cubes. Keep them covered and warm. They must be fully set, but a grey ring around the yolk means they were boiled too fiercely.

Bring milk to boil
While the eggs stand, bring the milk just to the boil in a separate saucepan, stirring across the bottom occasionally so it doesn't catch. Lower the heat and keep the milk hot. If it scorches, don't scrape the pan floor; pour the clean milk carefully into another pan and leave the caught layer behind.

Cook the white roux
Melt the butter in the heavy saucepan over medium-low heat. Add the flour all at once and stir continuously for 3 minutes, reaching into every corner. This is a roux blanc, a white roux: it should foam softly and lose the smell of raw flour without taking any brown colour. The cooking cannot be shortened, because this is the step that separates a smooth milk sauce from flour paste.
If the roux begins to colour, lower the heat at once. A faint cream tint will do no harm, but brown roux belongs to another family of sauces. - 4
Whisk in hot milk
Take the roux off the heat and whisk in about 1 cup of the hot milk. It will seize into a thick paste at first. Whisk until completely smooth, then add the remaining milk in several larger pours, smoothing each addition before the next. Return the pan to medium heat. If lumps appear, stop pouring and whisk vigorously over gentle heat; if stubborn ones remain, pass the sauce through a fine-mesh sieve before seasoning. Ça se rattrape.
- 5
Season and simmer
Season with the white pepper, nutmeg, and 1 teaspoon of the salt. Bring the sauce to a gentle boil, then lower the heat and simmer for the full 10 minutes, whisking often along the bottom and sides. The sauce is ready when it tastes rounded rather than floury and leaves a light ivory coat on the back of a spoon. Taste before adding more salt, especially if the sauce will accompany salt cod.
- 6
Fold in eggs
Remove the sauce from the heat and fold in the warm diced eggs, whites and yolks together, using a broad spoon so the cubes remain distinct. Do not boil the sauce after the eggs go in, and don't stir it into submission; broken yolks make the sauce muddy and heavy. Spoon it generously over boiled or gently poached haddock, fresh cod, or properly soaked salt cod. À table!
Chef Tips
- •Use whole milk and real butter. The sauce depends on their clean sweetness, and fat substitutes leave a waxy roux that never settles properly. We don't apologize for butter.
- •Keep the egg cubes near 1 cm. Smaller pieces disappear into the sauce, while larger pieces fall away from the fish instead of traveling with each spoonful.
- •Salt for the fish you are serving. Fresh haddock and cod can take the full seasoning; salt cod usually asks for restraint, even after soaking.
- •A dry Muscadet has enough freshness to cut through the milk and egg without bullying delicate fish. Serve the sauce immediately and let the fish remain the center of the plate.
Advance Preparation
- •The eggs may be hard-boiled up to 3 days ahead and kept unpeeled in the refrigerator. Before making the sauce, peel them, warm them for 5 minutes in hot water, dry them, and cut them into cubes.
- •The sauce base can be prepared without the eggs up to 2 days ahead. Press parchment directly against its surface, chill promptly, then reheat over gentle heat with a small splash of milk before folding in freshly warmed egg.
- •Once the eggs are added, the sauce is best served the same evening. Reheat leftovers gently without boiling; freezing makes both the milk sauce and egg grainy.
