Yes, I have made it. I just used a basic recipe, with 2 to 1 ratio of mustard to mayo, then I added a bit of chopped cilantro to the mix, along with the egg yolk. I think I used about 1 teaspoon of chopped cilantro, 2 tablepoons of mustard and 1 tablespoon of mayo (I used Veganaise) for 6 eggs. I think I would add a little bit more cilantro if I made it again, it wasn’t particularly spicy.
If I were making them for people who are not afraid to try something new, I think I would also add a tiny bit of chopped pickled jalapeño. Like 4 itty bitty pieces per egg. Pieces no bigger than 1/8 of an inch squares of the pickled peppers, or else it would be way too hot. No one in my family would eat these, so I’ve yet to try it.
Recently, I made some deviled eggs with smoked paprika. Those were really good. I think they’d even be better with the addition of cilantro. Some people will be freaked out by the appearance of them, though.
I’ve never used lemon or lime juice or vinegar in my deviled eggs.
I have also heard of adding some mashed avocado to the mix. I think that would be really good with the cilantro and it would make the whole mixture even greener, rather than yellow with green specks, plus you’d get a larger amount of filling to put back into the eggs.
