The last few packs of Viennas I've bought, the casings are EXTREMELY tough and chewy. There's no snap to them anymore. Maybe they're not using as many, because they're not producing as many (because of covid canceling ball games, festivals, etc.) and being older makes them tough?
Either way, what's the point of spending the extra money if there's no snap when you bite it?
Does anyone know if Nathan's hotdogs have snap?
