1 dozen eggs
1/3 cup Hellman's mayo
1T course mustard
2T soft butter
salt to taste
and your own splash of character!
Truffle Oil is great, but it only takes a drop. Chives, tarragon, basil - all good options. We have been on an infused salt kick lately. The Sun Ripened Tomato makes for a very tasty egg.
The greatest challenge is not to over cook the eggs. Consider a timer, or better yet, an Egg Cooker.
