Breath of the Wild
Mighty Fruitcake can be made in a lit Cooking Pot using Tabantha Wheat, Cane Sugar, Mighty Bananas and either an Apple or Wildberry; or by using Tabantha Wheat, Cane Sugar, Apple, Wildberry and any other ingredient with a "Mighty" effect (i.e., Mighty Thistle, Mighty Carp, Razorshroom, Razorclaw Crab or Mighty Porgy). The recipe which maximises the effect would be Tabantha Wheat, Cane Sugar, Apple/Wildberry, Mighty Bananas, and Mighty Porgy.
Regardless of the exact mixture, two different fruits must be used, at least one ingredient must have a "Mighty" effect, and there must be no ingredient with any other effect. The resulting dish will increase Link's offensive power to a variable degree and duration depending on the exact mixture used, as well as restoring an also-variable number of hearts. Cooking under a Blood Moon may increase this effect.
