If you have an Instant Pot I recommend the 5-5-5 method for making hard boiled eggs . Peel your eggs and slice in half lengthwise. Pop yolks out and add them to a zip lock bag.
Add mayo and mustard to the bag.
Seal bag and kneed until smooth and combined.
Add salt and pepper to taste.
Squeeze all the mixture into one corner of the bag.
Cut that corner off to make a 1/2 inch opening.
Pipe the filling into the egg whites and sprinkle with paprika.
