Just wanted to share this tip with everyone. You will be using your own recipe or search for the many fine ones here.
When you slice your egg in half, place the yolk into a ziplock bag. Add the rest of your ingredients to the ziplock and macerate or mush-up. Then cut off a small piece of a bottom corner and you have a little pastry bag to fill the eggs with. You can use a spatula to get every last bit. Sprinkle with paprika and there ya go!
