What is deidaras favorite food?

Deidara's favorite food is never explicitly stated in the Naruto series.

However, we do know he enjoys eating clay, which he uses for his art. This is because he considers his art to be his life and believes that eating the material he uses for it is a way to fully experience it.

It's also possible that he enjoys explosive foods, given his affinity for explosives. But this is pure speculation.

Ultimately, his favorite food is left up to interpretation, as the series doesn't provide a clear answer.
