It could mean "iced eggs". More likely, to my mind, it means "eggs in jelly". But I'm only guessing. So I made up something that fits the name, looks good, and can be fed to vegetarians. Personally I wouldn't eat it by choice, but it's not bad. Quantities produced enough for about 8-10 people to have a slice and decide that that's interesting but quite enough, thank you.
Take three hardboiled eggs. Separate the whites from the yolks, and chop both finely.
Put the yolks in the bottom of a suitable mould. Make up about 5 fl oz of gelatine, pour over the yolks, and leave to set in a cool place.
Now put the chopped whites on top of the yolk layer. Pour over about 8 fl oz of gelatine. Sprinkle chopped parsley over the surface. Leave to set.
When firm, turn out and slice. You should have a yellow layer, a white layer, and a thin green layer. Quite pretty. Serve cold, with salt.
