Baked blowfish with Sansho

Many people might know "Tettiiri" and "Tessa" as blowfish cuisine. When I was a child, my father liked baked blowfish with Japanese pepper, Sansho. They burned Sansho with it, and it smelled bad for me. It was the first experience of Sansho for me, then I hated it. But now I love Sansho.
