Smörgåskaviar ('sandwich caviar') is the Swedish word for a fish roe spread eaten in the Nordic countries and released in the 1950s.^[1][2] Despite its name, smörgåskaviar is not actual caviar, i.e. sturgeon roe. Instead, it is a paste made most often from cod roe and a variable mix of other ingredients. Whole roe is aged for up to two years in barrels in which the roe is layered with sugar, salt, and a sugar-salt brine, and turned regularly. After brining, it is smoked and then processed further. It is emulsified with oil such as rapeseed, soybean or cod oil. Other ingredients are added including potato flakes, tomato sauce, vinegar, onion, sugar, salt and sometimes dill or chives. The final paste contains 30–60% roe. It is sold in tubes in smoked and non-smoked variants.^[2][3]

Smörgåskaviar is mostly used on bread or a hardboiled egg.^[4]
