YumYum

YumYum was a pre-War company in the United States, producing packaged foods. YumYum Deviled Eggs was their major product.

Background
The box of deviled eggs lists "Dried" as one of the food's features, meaning that YumYum probably used freeze-drying to produce foodstuffs.

Before the War, YumYum ran promotional advertisements over the radio, such as the one alongside Part 1 of the Escape from the 42nd Century radio play. These advertisements would star "Devilish Dan", a devious young man who was always causing trouble; often to the chagrin of his neighbor, Mr. Mosely.

Appearances
The YumYum name appears in Fallout 3, Fallout: New Vegas, Fallout 4 and Fallout 76 on the box of their product, YumYum Deviled Eggs.
