Cooks comparing salt in barbecue sauces
If a tomato sauce or marinade will also contain stock, cheese, cured meat or a prepared condiment, comparing the tomatoes’ salt per 100g helps you account for one ingredient at a time.
Who is this choice for?
Cooks making a chunky grill-side sauce
If you want visible tomato pieces in a sauce for grilled vegetables, meat or beans, chunky chopped tomatoes offer that starting texture. Napolina describes its chopped tomatoes as suitable for thick sauces.
Cooks making a more uniform sauce
If a glaze or quick sauce calls for smaller tomato pieces, finely chopped pulp may suit the texture better. Check its salt figure separately rather than choosing on texture alone.
What should you check?
Start with the nutrition panel, then choose the texture for the dish and a pack size that fits how you will use opened tins.
| Priority | What to check | Your needs |
|---|---|---|
| Salt | Compare salt per 100g on the exact tin and read the ingredients for added salt. Nidirect describes 0.3g or less per 100g as low in salt; this is different from a comparative “reduced salt” claim. | I want to compare tins on the same basis, especially if the finished sauce will contain other salty ingredients. |
| Texture | Check whether the tomatoes are chunky and chopped or a finer pulp. Napolina describes its chopped tomatoes as suited to thick sauces; Mutti describes Polpa as finely chopped. | Visible pieces would suit my grilled-vegetable topping; for a more uniform glaze, I would choose a finer base. |
| Leftovers | Read the opened-storage directions on the specific tin before buying several. Marks & Spencer says to transfer and refrigerate its opened tomatoes and use them within three days; Joybuy gives a two-day instruction for its Napolina 400g listing. | If a recipe uses only part of a tin, I need a plan for the remainder before choosing a multipack. |
What can go wrong when choosing?
-
Assuming plain tomatoes have no salt
The listed 400g products differ: Marks & Spencer gives 0.02g salt per 100g, Napolina 0.10g and Mutti Polpa 0.30g. Mutti also lists salt as an ingredient.
Compare the current labels per 100g. A low salt figure alone does not establish a formal comparative “reduced salt” claim.
-
Choosing the texture after planning the sauce
Chunky chopped tomatoes leave visible pieces, while finely chopped pulp gives a more uniform starting texture. That difference matters when the sauce is intended as either a rustic topping or a glaze.
Choose the tomato format to match the finished dish; simmer a tomato-in-juice base if the sauce needs thickening.
-
Opening a multipack without a leftover plan
Opened-storage directions vary by product. Marks & Spencer specifies three days for its chopped tomatoes after transfer and refrigeration, while Joybuy specifies two days for its Napolina 400g listing.
Check each tin’s directions, transfer leftovers as instructed and choose a pack size you can use across planned meals.

These are product and grocery-range references for comparing labels and textures, not a statement that every item is sold on Joybuy.
M&S

- The fine texture offers a starting point for a more uniform sauce.
- Its listed salt figure is higher than those of the M&S and Napolina products compared here.
Tesco

Questions about salt, texture and storage
Does a plain tin of tomatoes necessarily contain less salt?
No. Compare the exact product’s salt per 100g and ingredients: Marks & Spencer lists 0.02g per 100g for its Chopped Italian Tomatoes, Napolina 0.10g for its Chopped Tomatoes and Mutti 0.30g for Polpa. Nidirect’s guide calls 0.3g or less per 100g low in salt, which is not the same as a formal comparative “reduced salt” claim.
Should I choose chunky or finely chopped tomatoes for a barbecue sauce?
Choose chunky chopped tomatoes if you want visible pieces in a thicker, rustic sauce; Napolina describes its Chopped Tomatoes as suitable for thick sauces. Mutti’s finely chopped Polpa offers a more uniform starting texture for a sauce or glaze. Compare the salt labels separately from texture.
What should I do with tomatoes left after opening a tin?
Follow that product’s storage directions, because the stated periods differ. Marks & Spencer says to transfer its Chopped Italian Tomatoes to a non-metallic container, refrigerate and eat within three days; Joybuy’s Napolina Chopped Tomatoes 400g listing says to transfer, cover, refrigerate and consume within two days.
Why compare the tin’s salt if the recipe uses other ingredients?
The tomatoes’ salt figure covers only the tomatoes, not stock, condiments, cheese or cured meat added to a barbecue dish. Compare tins per 100g, then consider the other ingredients in the finished sauce.
Is a supermarket product page enough to choose by salt content?
Use it to compare products while shopping, but check the label on the tin you receive before cooking. Marks & Spencer advises reading the label because product information can change.
