The eggs are meant to be a little runnier than this - that lovely inbetween softboiled and hardboiled, but we overshot the mark as we were too engrossed in the pre-show buildup! Even so, it was a very tasty dish. I'm thinking, too, that you could replace the mustard with curry powder for a, well, curried version.
You can use whatever mustard you enjoy, but be cautious with the hotter ones as you may need to use less or face the wrath of the mustard god. We used dijon because it is one of my favourites, and I had it in the house at the time!
Ingredients
4 eggs
4 tablespoons butter
4 tablespoons flour
1/2 litre milk
3 tablespoon mustard
salt to taste
Method
Boil eggs and boil until they are cooked as you desire (technically medium boiled is what you aim for, but do whatever you like best). Peel.Make a roux with the butter and flour. Add milk in gradually until you have a white sauce. Add mustard, stir through, season with salt and pepper to taste. If your eggs have cooled too much add them to the sauce to reheat, otherwise place eggs in bowl/s and pour sauce over.
Eat with rye bread, flatbread, or even with strips of crispy bacon... we served it with my flatbread recipe (just omitting the caraway!)
