A "Marianito" here in Bilbao is just a smaller sized vermouth. Most people order that instead of a" Vermouth". This "prepared" version is what we call a Marianito Preparado.. Every bar has their own recipe, but it's quite Vermouth-forward: something like 7 parts Martini - 2 parts Campari - 1 part Gin. Difford's recipe could be my favorite though, more Negroni-styled 😎
