We will be traveling about 2 hours to a surprise b'day party for my brother. After going over the menu with S-I-L, we agreed that I would bring deviled eggs. Am I crazy to try and transport them? Any suggestions/recipes would be appreciated. I thought I would cook the eggs, split them, make the filling here at home. I'll pack everything in a cold cooler. Then fill them when we get there. Will the whites fall apart and will I have a big mess on my hands? Should I take something else? I am looking at fingerfood ideas. Thank you.
