grand caperons are a variety of caper grown in italy. they are produced from the flowers of the caper plant, a shrub in the caprifoliaceae family, which are picked before they open completely, then salted and preserved in vinegar. Large capers are larger than ordinary capers and have a sweeter, more fragrant flavour. They are often used in cooking to add a tangy, aromatic touch to dishes, particularly meat and fish dishes.
