Sumac is a spice that comes from the bays of a wild shrub that grows in all Mediterranean regions, in particular in Sicily and southern Italy, as well as in certain parts of the Middle East, notably Iran. It is the fruit of the sumac of corroys, a dark red fruit, harvested at maturity, then dried before being reduced to powder to give the purple spice. In Iran, we place the table spice like salt and pepper with us, so that everyone can season at their convenience. On the nose, it is a scented and fruity spice, recalling balsamic vinegar. Its flavor is acerbic, that is to say that it makes a slightly rashed sensation feel at the level of the tongue, subtly bitter, phenomenon is due to the tannins of the spice.
