Home-canned tomato sauce. It keeps a year when the acid is right — which for modern low-acid tomatoes means added lemon juice or citric acid, every time.
How long it keeps
Unopened, this keeps 12 months — which is what puts it on the long shelf.
| As sold | Unopened, in the cupboard | Once opened |
|---|---|---|
| homemade, canned | 9–12 months | — |
Counted from the date on the package. Figures are the USDA FSIS FoodKeeper table's, for unopened storage at room temperature; FoodKeeper counts a month as 30 days.
The table was not pulled from USDA — fsis.usda.gov answers 403 to non-browser clients from this machine — so it came from a mirror of the data.gov dataset and its vintage is unverified. Treat a single figure as indicative, not as a use-by date.
