Ingredients
- 10 eggs
- 1 gallon water
- Dry, brown onion skins from about 5 onions
- 6 Tbsp salt
- 1 Tbsp whole caraway seeds
Directions
- Hard boil the eggs, drain, and chill them in ice water.
- Add the salt, onion skins, and caraway seeds to 1 gallon of water and boil for about 5 minutes. Strain the liquid (“Sol”) into another container, discarding the skins and seeds.
- Roll each chilled egg to crack the shell all over — this lets the Sol and its flavors enter the egg.
- Place the eggs in a large container (a glass mason jar works well) and pour the hot Sol over them.
- Let sit for at least 12 hours. Serve with hot Düsseldorf mustard.
