Lamb Rump:
Lamb rump usually needs to be cooked for many hours in sous vide, but this recipe is a bit different. Here the meat is cut from the leg of a good Danish lamb and aged for 60 days. This results in incredibly tender and flavorful meat, so in this recipe we suffice with giving it 2 1/2 hours.
Start by trimming the meat and seasoning it with salt and pepper.
Place it in a vacuum bag and cook it in
sous vide/water bath for 2.5 hours at 56 degrees Celsius (133 degrees Fahrenheit).
Remove the meat from the vacuum bag and pat it dry with a towel.
Use a blowtorch to sear the surface for a beautiful crust.
Stuffed Baked Potatoes:
Cut a cross in the top of each potato. Wrap them in foil and bake for 2 hours in the oven at 200 degrees Celsius (392 degrees Fahrenheit). They need to be completely tender and soft.
Dice onions, garlic, and bacon. Fry them in a pan until everything is crispy.
Remove the potatoes from the oven and unwrap from the foil. Let them cool slightly.
Scoop out the insides of the potatoes with a spoon and place in a bowl. Mash it lightly and mix with the bacon mixture, egg yolks, and chopped parsley. Season to taste with salt and pepper.
Return the filling to the hollowed potatoes and sprinkle with grated cheese.
Bake the potatoes for 10-15 minutes at 200 degrees Celsius (392 degrees Fahrenheit) on convection.
Onion Marmalade:
Slice the onions thinly.
Heat the oil in a pot and sauté the onions for a couple of minutes—they should not brown, just soften.
Add vinegar, balsamic, and sugar and reduce the heat.
Let the onions simmer on low heat for about 20 minutes.
Add honey, mustard, thyme, and salt. Let everything simmer until the onions are soft and the liquid has fully reduced.
Season to taste with salt and pepper. If the marmalade needs to be sweeter, add a bit more sugar, or if it needs more acidity, add a bit more apple cider vinegar.
Transfer the onion marmalade to clean, sterilized jars.
This recipe yields a large portion of onion marmalade. What is left can be stored in the refrigerator for about 14 days.
