Everyone makes deviled eggs differently, and I am no exception.
I cannot tell you how much I DESPISE mustard so I always omit it. If your mom uses vinegar, try some pickle juice. Instead of the traditional paprika, use Lawry's seasoning salt or cayenne (SPARINGLY) or skip that entirely and stick a chunk of pickle in it like my granny Ernie used to do or a chunk of crunchy bacon. You get the point.
If this is your first time making deviled eggs I encourage you to play around with different ingredients until you find the right mix for you!
Even if you've made deviled eggs a million times before, try something new. Feel free to add to these ingredients or omit what you don't like.
