Thanks for the link!
I’ve done the ziploc method before - finally “splurged” (not much) & got a tip/bag. The bag cleans up easy if you do it right away. The tip makes for gorgeous swirled filling .... people “eat with their eyes” so I think that’s one reason the deviled eggs are so popular plus, there’s one guy in the family who would probably eat the whole batch if he weren’t so polite!
I am sure they come out much prettier in a pastry bag.
