No, Worcestershire sauce and hoisin sauce aren't the best substitutes for one another, though they are helpful in a pinch. What these two sauces do have in common is their sweet and umami flavor. (*) That said, they have major differences. Worcestershire sauce is thinner than hoisin and with a fruitier flavor. On the other hand, hoisin is thicker and has a vinegar tang. We only recommend using these sauces as substitutes for one another when only a small amount is needed. If you plan on using Worcestershire as a dipping sauce, we advise against it because of the consistency. Fun fact: Instead of considering Worcestershire sauce to substitute hoisin sauce, we recommend using oyster sauce because of its similar consistency and seafood base.
