God's Tongue (神の舌 Kami no Shita) is a Superhuman Ability that grants the wielder an ultra-acute sense of taste.
God's Tongue is a unique skill that grants the wielder a superhuman level of taste beyond that of even the most seasoned food and ingredient experts. With it, one can detect even the tiniest imperfections in any dish with only a single taste.
Notable feats that can be achieved using the God's Tongue include:
- Being able to recognize and differentiate 8 different types of salt blindfolded.
- Being able to know exactly how long a specific portion of a dish was overcooked with a single taste of the broth.
God's Tongue is a highly valuable and respected skill in the culinary world that even Erina Nakiri, who was only 15 years old at the start of the series, could deem a dish unworthy and effectively end a chef's career with a single taste.
This skill is granted upon birth, although its full power did not manifest in Erina until she was roughly four years old where her one-shot version showed that she had superior taste as an infant, even noting that her mother's breast milk "tasted awful".
While a powerful tool, it is a double-edge sword as it has affected both Mana Nakiri and Erina. Mana's ability to detect culinary imperfections became so well developed, all food began to taste disgusting to her, causing her to stop eating in all together, only getting nutrients from IV drips. Erina on the other hand was subjected to a brutal training regimen by her own father at the age of four, to nurture her gift for his own goals. She nearly lost all joy in eating food and cooking as well had she not met Jōichirō Saiba.
