Did you know?
Sardines are named after Sardinia — the Italian island where they were historically abundant. They are one of the fastest-reproducing and most sustainably harvested fish in the ocean with a lifecycle of only 2-3 years. Portugal is the world's largest exporter of canned sardines with the industry dating to the 1880s. Portuguese canned sardines aged like wine — vintage sardine tins are sold as premium gifts.
