The **God of the Culinary Arts' Magic Spoon** (B-grade) was a spoon used by the God of the Culinary Arts to taste the saltiness of dishes. Over time, it absorbed the God of the Culinary Arts' aura, allowing anyone who ate with it to taste the flaws in their cooking.
Rita had used it many times, and it indeed allowed her to identify what was wrong with her dishes. But the problem was that while she could tell something was wrong, it never gave her a solution!

It required way too much intuition to figure out the process.
