Boil the eggs for 10 minutes, until they are hard boiled. Place the eggs in a pot with an inch of cold water. Bring the water to a boil, and let the eggs cook for 10 minutes. After ten minutes, carefully place the eggs in cold water to stop the cooking process.
Peel the shells off all of the eggs.
Cut each egg lengthwise so that each half can sit by itself flat on a plate.
Take the cooked yellow yolks out of each egg white and place in a bowl.
Mix the cooked egg yolks with the mayonnaise, mustard, herbs and spices. Blend it well so that the mixture is smooth. (Add more mayonnaise if necessary.)
Using two teaspoons, gently scoop the egg yolk mixture to form small balls and place in each egg white half.
Garnish with a pinch of extra thyme and serve when ready.
These French deviled eggs can easily be prepared a few hours in advance. Just leave them in the fridge and take them out 15 minutes before you are ready to serve so that they get to room temperature.
