Staghorn Sumac (Rhus typhina) Staghorn Sumac has the most delicious sour flavor of the summer. It carries aromas which clarify the fact that Sumac hails from the same family as mangoes and cashews (Anarcadiaceae).
Fresh sumac, collected at the right time, is an experience like no other. It is exceedingly rich and sour, the flavors bring your mouth alive and your nervous system to attention. Sumac can be found in such abundance in this country that it should be a part of everyone's diet (providing they are not allergic). Since it is in the same family as mangoes and cashews (and Poison Ivy for that matter), anybody suffering from allergies to mangoes or cashews should proceed with due caution.
