When I was a child these were my favourite thing about holidays with my grandma. Mine are never as good as hers no matter how hard I try....actually they are quite easy:
Boil eggs, as many as you like, until yolks are cooked. Pour out hot water and add cold water to cover. Once cool enough, peel eggs and slice in half lengthwise. Remove the yolks into a bowl and mix with mayonnaise, seeded mustard, salt, pepper and the leftover juice from sweet pickles (don't leave this out-it's what gives the flavor). Fill each egg white with the mix and top with sliced sweet pickles and sweet paprika.
