What should you check?
Start with the quantity your recipe calls for, then choose a tomato format and pack size you can use and store.
| Priority | What to check | Your needs |
| Pack quantity |
Four 400g tins contain 1.6kg in total. Compare the recipe’s tin or gram quantity with the pack size, and allow cupboard space for unopened tins. |
My recipe needs more than one tin, or I will use the spare unopened tins for another meal. If neither applies, individual tins may be enough. |
| Tomato texture |
Check whether the product is regular chopped, finely chopped or whole peeled tomatoes. Napolina describes its chopped product as chunky, while Mutti describes Polpa as finely diced. |
For a base with visible pieces, I would start with chopped tomatoes. If I want a finer dice, I would choose a finely chopped product; whole peeled tomatoes may need preparation for my recipe. |
| Opened tins |
Read the exact product’s refrigeration and use-within instructions. Sainsbury’s lists two days after opening for Napolina’s four-pack; the cited ASDA tin says four days, and Mutti’s four-pack says five days. |
If the recipe leaves part of a tin unused, I need a plan to store it as its label directs and use it within the stated period. |
| Product label |
Check the ingredients and allergy information on the exact product, along with its date and storage instructions. Do not assume different tomato formats have identical labels. |
I want to know what is in the tins I am buying and how to keep any that remain unopened. |

Common questions
How much tomato is in four 400g tins?
A 4 x 400g pack contains 1.6kg in total. Sainsbury’s describes Napolina’s pack as approximately eight 200g portions, but the quantity needed for a family dinner depends on the recipe’s tin or gram measure.
Should I choose chopped or finely chopped tomatoes for a Mexican-style dinner?
Choose regular chopped tomatoes if you want visible pieces, or a finely chopped product if a finer dice suits the dish. Napolina describes its chopped tomatoes as chunky, while Mutti describes Polpa as finely diced; these are product descriptions, not a quality ranking.
How should leftover tomatoes from an opened tin be stored?
Follow the instructions on the exact product. The cited Napolina four-pack says to refrigerate and use within two days; ASDA’s 400g tin says to transfer leftovers to a suitable non-metallic container, refrigerate and use within four days; Mutti’s four-pack says to refrigerate and consume within five days.
What does a best-before date mean on tinned tomatoes?
GOV.UK says a best-before date relates to quality, whereas a use-by date relates to safety, and identifies canned tomatoes as a best-before food. Follow the tin’s storage instructions and check its packaging and contents before use.
