I always recommend assembling your charcuterie platter on the same day whenever possible. This will give you the best presentation without any veggies drying out, crushing your delicate details, or adding any condensation. However, that doesn't mean you can't work ahead! The day before your event, fold the salami roses, rinse and dry your fruits, mold your little cheese bunnies, and make your deviled eggs. With those ready to go, you'll have less work to do on the day of, and you'll be able to assemble your Easter-themed appetizer board and go. If you know you won't have time to make your board the day of, try assembling everything except the deviled eggs on your tray, then wrapping it very well with plastic wrap.
