To get perfectly cooked eggs, put them in a pot of cool water, place them on the stove and boil them for a half hour. Once boiled, remove the eggs and refrigerate for 1-2 hours.
Once the eggs are cool, remove the shells by carefully tapping around the center and peeling. Crack and peel very carefully so the egg is pristine and free of tears and dents.
Slice 6 of them carefully in half (the other 6, you don’t need to be so careful because you’ll be using just the whites for filling).
Remove the yokes of all eggs by simply sliding them out, or using a very tiny spoon. Discard the yokes. Wash and dry you’re eggs so there is no egg yoke on any of them. You want them all pristine.
Set aside your 12 prettiest cut egg halves, and put the other 6 egg whites into a food processor with your mayo, horseradish and creamy cheese. Pulse until fully mixed. If you’re filling appears a little dry, give it a taste, and see if it could use either more horseradish, mayo or triple cream. Otherwise, you’re ready to pipe your filling into your eggs!
Carefully pipe your white filling into your egg halves. I highly suggest using a nice piping tip and pastry bag for this kind of egg, rather than spooning the filling in. It needs to look as elegant as possible.
Place your tiny chopped radishes or caviar carefully around the side of your eggs and serve!
