The game-changer that saved my reputation: temperature control is everything. Never assemble warm egg salad - those proteins will break your mayo emulsion faster than you can say 'office potluck disaster.' This recipe comes from someone who's made every possible mistake, wasted $200 learning what NOT to do, and finally cracked the code through expensive trial and error. My sister-in-law who once said my cooking 'needed work' now specifically requests this for family gatherings.
