Fresh anchovies are an oily fish that look and taste similar to sardines. They vary in size and can be bought either fresh or cured. Cured anchovies were originally left whole and packed in salt, but now they tend to be boned, cleaned and preserved in salt or oil and sold in cans or jars. Fresh anchovies don't travel well so are best eaten in the Mediterranean. They're not easy to find in the UK because there isn’t a great demand for them, but try Italian or Spanish delis. Otherwise buy them cured or preserved - supermarkets do a limited range but delis tend to sell a wider range.
