They took the yolks and put them in a bowl and mixed in all the other ingredients (except the paprika).
My very smart cousin suggested putting all of the filling into a sanwich bag since we don't have a fancy pastry bag like they show in the picture. Check out this neat homemade pastry bag that put the filling into all of the eggs with a super neat way. Cookbook can be seen in the background too :)
Here is the finished product sprinkled with paprika. My husband and cousin enjoyed their special treat and I didn't have to make them so I enjoyed that :)
