Ingredients

Equipment Needed

• •Heavy frying pan for the bacon
• •Wide pot for boiling the eggs
• •Whisk
• •Slotted spoon
• •Kitchen timer

Instructions

1. 1

   Render the bacon

   Put the bacon lardons into a cold, heavy frying pan and set it over medium heat. Starting cold lets the fat render slowly before the meat browns, which is how you get bacon that is crisp all the way through rather than burnt on the outside and chewy inside. Cook, stirring occasionally, for about ten minutes until the pieces are deep gold and the kitchen smells of smoke and salt. Lift the bacon out with a slotted spoon onto kitchen paper and set aside. Leave the pan where it is.

   Do not throw away the bacon fat. A spoonful stirred into the finished sauce is a quiet Jutland trick that deepens the whole dish.
2. 2

   Soft-boil the eggs

   Bring a wide pot of water to a rolling boil. Lower the eggs in gently on a spoon so the shells do not crack against the bottom. Boil for exactly six and a half minutes for whites that are just set and yolks that are still soft and bright at the centre. Six and a half minutes is the number to remember. Any less and the whites slip around when you peel them. Any more and you lose the molten yolk, and the whole point of this dish is that the yolk meets the mustard sauce and the two become one thing.

   Lift the eggs straight into a bowl of cold water as soon as the timer goes. This stops the cooking and makes them easier to peel.
3. 3

   Start the roux

   Melt the butter in a medium saucepan over gentle heat. When it stops foaming, add the flour all at once and whisk it through. Cook this paste for two full minutes, stirring the whole time. You are not trying to colour it. You are cooking the raw flour taste out of it, and two minutes is what it takes. If you skip this step, the finished sauce tastes chalky and flat.

4. 4

   Build the sauce

   Pour the warmed milk into the roux in a slow, steady stream, whisking constantly. Warm milk into a warm roux gives you a smooth sauce without lumps. Cold milk into a warm roux is how you get a sauce that looks like porridge. Keep whisking as it thickens. After about five minutes you should have a silky sauce that coats the back of a spoon and leaves a clean line when you draw your finger through it. That is the consistency you want.

5. 5

   Season with mustard

   Take the sauce off the heat and whisk in both mustards, the sugar, a good pinch of salt, and a grind of white pepper. Taste it. The sauce should be sharp and warming but rounded, never harsh. If it tastes thin, add a little more coarse mustard. If it tastes too sharp, another pinch of sugar softens it. You'll know when it's right because it will taste finished, not like something still looking for its last ingredient.

   Never boil the sauce once the mustard goes in. Heat dulls the mustard's flavor and makes the sauce taste bitter. Keep it warm, nothing more.
6. 6

   Peel the eggs

   Peel the cooled eggs carefully. Soft-boiled eggs are fragile, so work under a trickle of cold running water and start the peel at the wide end where the air pocket sits. The shell should come away in large pieces. Trim any stray bits of white. Keep the eggs whole for now. Cutting comes at the plate.

7. 7

   Warm the eggs in the sauce

   Return the sauce to the lowest possible heat and lower the peeled eggs into it one at a time. Spoon the sauce over them gently so they warm through without cooking further. Two minutes is enough. You want the eggs hot on the outside and still molten at the centre, coated in pale yellow sauce like they've been dressed for Easter lunch.

8. 8

   Assemble and serve

   Place a thick slice of rugbrod on each plate. Lift two eggs onto each slice with a slotted spoon and halve them gently so the yolks begin to run. Spoon generous mustard sauce over the eggs and let it pool on the bread. Scatter the crisp bacon across the top, then the dill fronds, then the cress if you have it. Serve at once while the eggs are warm and the sauce is still glossy. Tak for mad.

Chef Tips

• •The quality of the mustard is the whole dish. Use a real Danish coarse mustard if you can find one, the kind with visible mustard seeds and a sharp, clean heat. Supermarket yellow mustard alone will give you a sauce that tastes flat and one-dimensional.
• •Room-temperature eggs crack less and cook more evenly. Take them out of the fridge fifteen minutes before you start, or warm them briefly in a bowl of tepid water.
• •Rugbrod is not optional here. The dark, dense rye is what holds up to the sauce. A slice of white toast goes soggy in seconds and the whole architecture collapses. If you cannot find rugbrod, use the darkest, densest rye bread you can get your hands on.
• •A cold beer or a small glass of aquavit belongs alongside this plate. The bitterness of the beer and the bite of the spirit cut through the richness of the sauce in a way that makes the whole meal feel balanced.

Advance Preparation

• •The bacon can be rendered earlier in the day and warmed briefly in a dry pan before serving.
• •The mustard sauce can be made up to an hour ahead and kept warm over the lowest heat, stirred occasionally. Press a piece of buttered baking paper directly onto the surface to stop a skin forming.
• •The eggs must be boiled and assembled just before serving. This is not a dish that holds. Cold eggs in cooled sauce is a different plate, and not the one you are making.
