Myths are stories, told from generation to generation, with the purpose to calm the soul for unexplained facts, also as dictate an expected behavior.

I found this great review from a TotC session where some blind-tests were made and they found out that:

  • Vermouth and lime juice were acceptable if kept refrigerated ;
  • Dry shake does add mouth feel to cocktails with egg.

I found this information very useful since I tend to keep away from buying vermouth for myself and also that pre-squeezed lime juice has a weeked shelf-life.
