there is a variety from mullet instead of tuna, which is described as follows:
\"Also called Sardinian caviar, bottarga is made with salted and pressed mullet roe. It looks like a square brownish-orange salami and keeps for months in the refrigerator if well wrapped. Bottarga is sliced paper-thin and served with olive oil as an antipasto, and it flavors one of Sardinia\'s most famous pasta dishes, maccheroni alla bottarga.\"
