Scorching Fruit and Mushroom Mix
"Grants a low-level attack enhancement in hot places. This dish contrasts the sweetness of fruit with the savoriness of mushrooms."
Tears of the Kingdom
If Link cooks Fire Fruit with a "neutral" mushroom or mushrooms - Hylian Shroom or Skyshroom - in a Cooking Pot, he will create Scorching Fruit and Mushroom Mix. Eating this will give him Hot Weather Attack - Attack Up in places requiring Heat Resistance - in addition to restoring a number of hearts. Cooking under a Blood Moon may increase this effect.
If an ingredient with a different effect is added, the effects will cancel out and leave the result as plain Fruit and Mushroom Mix or similar once cooked. There is no benefit to cancelling out effects in this manner.
A basic meal of a Skyshroom and a Fire Fruit, with no blood moon or other critical success involved, will restore 1 heart and give Link Hot Weather Attack for one minute and 30 seconds. Note that "Hot Weather Attack" does not itself give Heat Resistance, and heat-resistant Armor such as the Desert Voe Set must be worn to avoid taking damage.
