What should you check?
Start with the quantity your cooking plan calls for, then choose the tomato cut and check the label of the pack you intend to use.
| Priority | What to check | Your needs |
| Pack quantity |
Count the tins and check their individual weight. A 4 x 400g pack contains 1.6kg; Sainsbury's describes the Napolina pack as approximately eight 200g portions, not a fixed recipe yield. |
Will I use several tins for the roast-day dish, or do I have later meals planned for the unopened ones? |
| Tomato cut |
Read the texture description, not just the word “chopped”. Napolina describes its standard chopped tomatoes as chunky; Mutti describes Polpa as finely chopped. |
For a thick sauce with visible pieces, standard chopped appeals to me. If the dish calls for a more even base, I would look at finely chopped tomatoes. |
| Ingredients |
Check the exact tin. Sainsbury's lists tomatoes 99.9% and citric acid for its Napolina pack; Cirio lists 65% chopped tomatoes, tomato juice and citric acid for its chopped tomatoes. |
If an ingredient or the finish of the sauce matters to me, I need the label for the product I am buying rather than an assumption about the category. |
| Opened tins |
Follow the pack's transfer, refrigeration and use instructions. The Sainsbury's Napolina label says to refrigerate and use within 2 days after opening; the Joybuy Mutti listing states 5 days. |
I may use only part of a tin for the roast, so I need to know how to keep the remainder for another meal. |

Questions about packs and leftovers
How much tomato is in a four-tin pack?
A 4 x 400g pack contains 1.6kg. Sainsbury's describes the Napolina pack as approximately eight 200g portions; that is a label serving guide, not the amount every Sunday roast recipe will require.
Should I choose standard or finely chopped tomatoes for a roast-day sauce?
Choose standard chopped tomatoes if you want visible pieces in a thick sauce. For a more even base, consider finely chopped tomatoes: Mutti describes its Polpa as consistent in texture and suited to long cooking or high temperatures.
Can I keep tomatoes left over from an opened tin?
Yes, if you follow the particular product's after-opening instructions. The Sainsbury's Napolina label says to refrigerate and use within 2 days, while the Joybuy Mutti listing says to refrigerate and consume within 5 days.
What should I check if ingredients matter to me?
Read the ingredients on the exact tin before use rather than assuming all chopped tomatoes have the same formulation. The Sainsbury's Napolina label lists tomatoes 99.9% and citric acid; Cirio lists 65% chopped tomatoes, tomato juice and citric acid for its product.
