Deviled Eggs with Colman's Mustard

Cook the eggs - Add the eggs and 2 cups of water to your Instant Pot. The eggs should be placed on a rack so that they're not touching. Set the Instant Pot for 10 minutes, and do a quick release when the cook time has elapsed. Plunge the eggs into cold water.
Prep the eggs - Carefully peel the eggs. With a sharp knife, slice each egg in half and pop the yolk into a bowl.
Make the filling - Smash the egg yolks with a fork. Stir in the mayonnaise and the Colman's Mustard.
Fill the eggs - Fill the eggs however you do it normally - either use a piping bag or simply use a spoon.
Chill - Chill into the fridge until ready to serve.
