Buffet cooks using tomatoes in several dishes
If sauces, casseroles, dips or bakes will sit alongside cheese, cured meats or other seasoned foods, the tomato base is one part of the salt calculation.
Who is choosing these tomatoes?
Shoppers choosing a tomato texture
Chunky chopped tomatoes suit dishes where visible pieces are welcome. Finely chopped pulp offers a more even base for a sauce or soup.
Multipack shoppers planning ahead
Several dishes may call for several tins. Compare salt per 100g independently of pack size, then check that the quantity and best-before dates suit your plans.
What should you check before buying?
Start with the salt figure per 100g, then choose the tomato format and pack quantity that fit your recipes.
| Priority | What to check | Your needs |
|---|---|---|
| Salt per 100g | Compare the same per-100g measure on each can. The NHS low-salt labelling threshold is 0.3g or less per 100g; check the ingredient list separately for added salt. | I want to know how much salt the tomatoes contribute before adding stock, cheese or seasoning to a buffet dish. |
| Tomato texture | Check whether the tin contains chunky chopped tomatoes, finely chopped pulp or whole plum tomatoes. Decide whether the dish needs visible pieces or a more even base. | For a thick sauce, I may want tomato pieces; for a smoother dip or soup, I can choose a finer texture or plan to blend the tomatoes. |
| Exact variant | Read the nutrition and ingredients on the can you are buying. Do not transfer a plain chopped-tomato figure to a flavoured or differently prepared variant. | I want the salt comparison to apply to the actual tins going into my recipes, not just to a familiar brand name. |
| Quantity and storage | Count the tins needed for your dishes and check best-before dates. For leftovers from an opened tin, follow that product’s storage directions. | A multipack helps with planning only if I will use the quantity; I also need a plan for any tomatoes left after preparation. |
What can catch you out?
-
Assuming every tomato tin is free of added salt
Mutti lists salt among the ingredients of its Polpa, while its stated salt figure is 0.30g per 100g. That matters when the recipe also uses seasoned ingredients.
Read both the ingredient list and the salt-per-100g line, then decide how much seasoning the finished dish needs.
-
Comparing figures based on different quantities
A whole-tin figure and another product’s per-100g figure do not provide a like-for-like comparison.
Compare salt per 100g first. If you need the contribution from a recipe, calculate it using the quantity of tomatoes you will use.
-
Using one variant’s label for another
Ingredients and nutrition figures apply to the particular product, not automatically to every flavour or tomato format from the brand.
Check the exact can, particularly if you switch from plain chopped tomatoes to a flavoured or finely chopped version.
-
Buying a multipack without a menu plan
A larger pack may leave more tins than a small buffet needs, while availability can change before Boxing Day.
Work out the quantity for each dish and check best-before dates and availability when you shop.
Brand and product-line references
These figures describe specific tomato products, not every tin made or sold under each name.
M&S
M&S Chopped Italian Tomatoes are a chopped-tomato option for recipes where the tomato base should contribute little salt.
- M&S lists 0.02g salt per 100g and ingredients of Italian chopped tomatoes, tomato juice and citric acid.
- Check the current can label: M&S advises that product information can change.
Napolina
Napolina describes its plain chopped tomatoes as chunky and suited to thick sauces.
- Napolina lists 0.10g salt per 100g for its chopped tomatoes, within the NHS low-salt labelling threshold.
- Check flavoured and other tomato variants separately rather than applying the plain product’s figure to them.
Mutti
Mutti Polpa is finely chopped tomato pulp for dishes needing a more even tomato texture.
- Mutti lists 0.30g salt per 100g, meeting the NHS low-salt labelling threshold of 0.3g or less per 100g.
- Polpa contains added salt and sits at that threshold, so account for other seasoned ingredients in the dish.

Questions about salt and storage
What counts as low salt on a tinned tomato label?
The NHS defines low salt as 0.3g salt or less per 100g. Compare that per-100g figure across tins: M&S lists 0.02g for its Chopped Italian Tomatoes, Napolina lists 0.10g for its Chopped Tomatoes, and Mutti lists 0.30g for Polpa. Check the current label of the exact variant you buy.
Does a low-salt figure mean no salt was added?
No. Mutti lists added salt in its Polpa ingredients even though its 0.30g-per-100g figure meets the NHS low-salt labelling threshold. Read the ingredient list as well as the nutrition panel if added salt affects your choice.
How should I store tomatoes left after opening a tin?
Follow the instructions for the particular product. M&S says to transfer its opened Chopped Italian Tomatoes to a non-metallic container, refrigerate them and eat them within 3 days; a Joybuy listing for Mutti Finely Chopped Tomatoes says to refrigerate after opening and consume within 5 days.
Is a retailer’s product page enough to choose a tin?
Use it to plan, then check the can you receive. M&S advises that product information can change, so the current ingredients, nutrition and storage instructions on the pack matter when making your final choice.
