What ends it. The food and the tin slowly react. That changes taste and texture rather than making it unsafe. How to make it last longer

Sardines in tomato sauce

Sardines in tomato sauce are oily fish, and that is the point of them. The NHS says a healthy diet should include at least one portion of oily fish a week, around 140 g, and names sardines among them (NHS). On a long-life diet, a tin of sardines is the easiest way to meet that.

Per 100 g with their sauce, CoFID records 18.5 g of protein and about 3 g of omega-3 fatty acids. Omega-3 is one of the few nutrients a cupboard of tins and dried goods genuinely runs short of, and oily fish is where nearly all of it comes from. The NHS also notes that canned sardines contain bones you can eat.

Cooking with them

The sauce is a seasoning, not a filler: it goes into the dish with the fish. Sardine and tomato curry builds a curry on it, and sardine and breadcrumb pasta breaks the fish through pasta with crisp crumbs for crunch.

How long they keep

USDA FoodKeeper gives low-acid tins, fish included, two to five years; we plan on two. Once opened, the Food Standards Agency advises against storing food in the tin (FSA). Decant, refrigerate and eat within two days.

Per 100 g there is 315 mg of sodium, about 0.8 g of salt: between the NHS’s low and high marks, so taste before seasoning.

Storage

Cool, dark. The sauce is a seasoning, not a filler: it goes into the dish with the fish.
