Upon retrieving a Rock Roast for Bladon, the Goron will Cook it using the nearby Cooking Pot, making a Deliciously Grilled Rock Roast. The smell from the Deliciously Grilled Rock Roast will wake Gonguron from his stupor. Eating the Deliciously Grilled Rock Roast restores Gonguron's strength, allowing him to hurriedly break through the nearby wall of hard rock, revealing Kayra Mah Shrine. After this, Rock Roasts will no longer appear at Gortram Cliff.
Link is unable to cook one should he take one to a different Cooking Pot or places it on Aji's grill, meaning Bladon is the only way to turn it into a Deliciously Grilled Rock Roast.
↑"Yummy! Delicious! Incredible! That texture! That crunch! Ooooh, and that gritty feeling as it glides down my throat! OH! Yes! Can't forget that savory flavor of condensed minerals seared in high heat to perfection! It's a taste explosion! It's restoring my strength! I'm like a phoenix reborn and ready to fly! In fact, I AM Death Mountain!! Your cookin' is the best of the best, brother!" — Gonguron (Breath of the Wild)
