Taste test the filling at this point to see if you need to make any adjustments.
I prefer piping the filling in with a zip lock baggie because I have more control over the amount of filling for each egg; plus makes a fancier presentation.
Some recipes say you can crumble and mix all your ingredients right in the sandwich bag to save some dishes… but Mom doesn’t like that method because it’s harder to get the yolk crumbled well and you might end up with a lumpy filling or large chunks of yolk in your deviled egg filling.
