As it is not a meat food item, Wigfrid will not eat it.

In all DLCs, Dragonpie increases the player's perceived temperature by 1 degree per second for 10 seconds when consumed. The same is true for Don't Starve Together.
This food item can heal much more Health and Hunger than most of its ingredients. Due to this, and the rarity of Dragon Fruits, it is best to cook Dragonpies rather than eating Dragon Fruits on their own.
In the Hamlet DLC, it is best to completely avoid buying Dragonpie from The Sterling Trough Deli, as it is nearly twice as expensive as meals such as Honey Ham which have similar stats.
Because Wurt will not eat meat, Dragonpies are a fairly decent substitute to Honey Ham, Beefy Greens and Bacon and Eggs, as they have a fairly identical statline of large hunger and decent healing. Dragonpie also boasts an impressive 15-day spoilage time, which can be considerably useful.
Trivia
During the Pig Fiesta event in Hamlet, Dragonpie takes on a more festive appearance.
