Piping is a nice touch. Well.... That's what I think.Curried eggs in the UK means exactly that - a curry made with eggs in it. Devilled eggs or stuffed eggs are much more popular in the States than here. Here they are considered a retro buffet - rather like cheese & pineapple on sticks or cocktail sausages on sticks. I can remember then appearing at buffets in the 60's & early 70's but virtually never these days.
As Nigella Lawson says:
However she goes on to say:
I do make them sometimes in lots of different ways with all kinds of spices added and often a little yoghurt as I can't eat mayo (& anyway, it saves on calories) - but I don't bother with a piping bag.
