Keep a 227g tin for small meals if avoiding an opened remainder matters more than having a full recipe quantity. Choose a 400g tin for recipes written around that size; then compare chopped texture, ingredients and salt per 100g, and check the instructions for any leftovers.
A smaller tin is worth considering when one dish needs only a little tomato and you would rather not store a substantial remainder. Joybuy labels its Napolina 227g chopped-tomato tin as one serving; the amount you need still depends on the recipe.
If your usual sauce, stew or chilli calls for a 400g tin, start with that quantity. You can then choose between chunkier and finely chopped tomatoes according to the dish.
Check the ingredient list and declared salt per 100g on the particular tin. Similar-looking chopped tomatoes need not have the same ingredients or salt declaration.
Choose the quantity for your usual recipe first, then check texture and the pack label before deciding which tin to keep.
| Priority | What to check | Your needs |
|---|---|---|
| Tin size | Compare the stated net quantities: Napolina has a 227g chopped-tomato tin, while the named Mutti and M&S products are 400g. Check the quantity your recipe calls for. | I usually make one small meal and would rather open less tomato, or I cook recipes that call for a full 400g tin. |
| Texture | Napolina describes its chopped tomatoes as chunky. Mutti describes Polpa as finely chopped pulp and juice suitable for longer cooking; check whether you want pieces of tomato in the finished dish. | Visible tomato pieces matter in my dish, or I want a more finely chopped base for a sauce. |
| Ingredients and salt | Read the current ingredient list and compare salt on the same per-100g basis. The M&S listing declares 0.02g salt per 100g; Joybuy lists 0.30g per 100g for Mutti Finely Chopped Tomatoes 400g. | I want to see what is already in the tin before seasoning the dish. |
| Leftover storage | Read the instructions for the specific tin after opening. Joybuy says to refrigerate its Napolina 227g product in a non-metallic container and use it within two days; M&S gives three days for its 400g chopped tomatoes. | If I will use only part of a tin, I need to know how to store the remainder and when to use it. |
A 400g tin supplies the quantity for recipes written around a standard tin, but a small meal may leave an opened remainder.
Choose the tin size for the meal you usually make. If you open more than you use, follow that product’s instructions for storing the rest.
Storing an opened remainder takes space and means planning another use for it.
Napolina describes its chopped tomatoes as chunky, while Mutti describes Polpa as finely chopped pulp and juice. Whole tomatoes are another format when retaining their shape matters to the dish.
Check the format before buying: choose pieces when you want them visible, or finely chopped tomatoes when the recipe calls for a more even base.
Declared salt differs between named products: M&S lists 0.02g per 100g for its chopped Italian tomatoes, while Joybuy lists 0.30g per 100g for Mutti Finely Chopped Tomatoes 400g.
Compare current ingredients and salt per 100g on the tins you are considering, rather than relying on the front-of-pack description alone.
GOV.UK distinguishes best-before dates, which concern quality, from use-by dates, which concern safety, and gives canned tomatoes as a best-before example. Directions for an opened tin are a separate matter.
Read the date and storage wording on the can. Once opened, follow that product’s instructions for transferring, refrigerating and using any remainder.
