Capers (in Spanish: alcapparas)
Capers are the unopened flower buds, preserved in salt or in vinegar, from the Capparis spinosa, also called Flinders rose. This plant is native to the Mediterranean, and can also be found in the area of Mazarrón. In a way it is tempting to pick the flower buds yourself to make capers.
But not from the plant that is photographed here. We fear that this one could be contaminated because it grows in a mining site.
