I just happen to love Pickapeppa sauce, and putting some of it in mayonnaise is easy, as would be adding Indian lime pickle, or mango chutney, plus hot sauce for a bit of heat, or even beet horseradish.
For a more surprising visual effect and a more complex dish, instead of halving the eggs, cut off the tops and bottoms, scoop out the yolks without damaging the whites, make the deviled yolk mix, then put it in a pastry bag and fill the eggs by piping the egg mixture back into the hollowed-out whites. Serve them standing up with the mayonnaise spooned over. A whole platter of these eggs for a buffet will pleasantly surprise everyone.
