I bought some sasa-kamaboko.
笹かまぼこ is a specialty 蒲鉾 (fish cake) of 仙台 and Miyagi Prefecture, flattened and grilled into a fan shape resembling a 笹 leaf, rather than the usual half-cylinder loaf shape of ordinary 蒲鉾.
Writing
Also written 笹蒲鉾, but 笹かまぼこ (partial hiragana) is the standard spelling on packaging and menus.
Often sold as a souvenir (お土産) from the Tohoku region, and eaten as is, grilled again, or torn by hand as a snack with beer.
