Curry cooks comparing sugars
If you use chopped tomatoes as a curry base, the per-100g nutrition panel helps you compare tins without mistaking a seasoned tomato product for a plain one.
Who benefits from checking tomato labels?
Cooks who season their own sauce
If you add your own spices, herbs and salt, read the ingredients list as well as the nutrition panel. Sugars naturally present in tomatoes still appear under “of which sugars”, even when sugar is not listed as an ingredient.
Households cooking several servings
If you make curries in batches, compare pack quantities with the space you have to store them. For any opened tin, follow its instructions for transferring and keeping leftovers.
What matters when choosing tomatoes for curry?
Start with the ingredients and per-100g sugars figure, then choose a texture and pack quantity that suit the curry you intend to make.
| Priority | What to check | Your needs |
|---|---|---|
| Declared sugars | Compare “of which sugars” per 100g on the same basis. ASDA Groceries lists Mutti Polpa at 2.8g per 100g; Sainsbury's Groceries lists its Italian chopped tomatoes at 3.5g per 100g. These are figures for the specified products, not every variant. | I want to compare the amount of sugars declared in the tomato base, without assuming the lowest figure across a few tins is the lowest available everywhere. |
| Ingredients | Read the exact tin's ingredient list for sugar and other seasonings. ASDA Groceries lists sugar in its Chopped Tomatoes with Herbs, but not in its plain Chopped Tomatoes. | I would rather decide how to season my curry than rely on a pre-seasoned tin. I still need the nutrition panel to see its total sugars. |
| Texture | Check whether the product is described as finely or ordinarily chopped. Mutti describes Polpa as finely chopped and suitable for longer cooking; the finished texture also depends on how you prepare the sauce. | For a longer-simmered curry, I may prefer a finer tomato base; for a sauce with visible tomato pieces, I can choose a different chop. |
| Pack and leftovers | Check the number of tins, each tin's size and the opened-product instructions. Joybuy's Napolina 400g listing says to transfer opened contents to a non-metallic container, refrigerate and use within two days. | A multipack makes sense for the curries I have planned only if I can store the unopened tins and use each opened tin as directed. |
Buying mistakes to avoid
-
Using the sugars figure as an ingredients list
The number under “of which sugars” includes sugars in the tomatoes. ASDA Groceries lists 2.9g sugars per 100g for its Chopped Tomatoes with Herbs, yet sugar also appears in that product's ingredients.
Check ingredients for added sugar first, then compare per-100g sugars between tins of a comparable format.
-
Calling a plain tin sugar-free
Not listing sugar as an ingredient does not mean the tin contains zero sugars. ASDA Groceries lists 2.8g sugars per 100g for Mutti Polpa, whose displayed ingredients are tomatoes and salt.
Describe the figure you are comparing rather than treating “no sugar listed” and “no sugars” as interchangeable.
-
Buying a large pack without planning opened tins
Multipacks contain individually sized tins, while storage instructions apply once a tin has been opened. Joybuy's Napolina 400g listing instructs shoppers to transfer opened contents, refrigerate them and use them within two days.
Choose a pack quantity you can store, and check the instructions on each product before planning leftovers.
-
Assuming every chopped tin has the same texture
Mutti describes its Polpa as finely chopped and suited to longer cooking. A tin described only as chopped need not produce the same texture in your curry.
Check the product's description if you want a finer tomato base, rather than choosing solely by the sugars figure.
Brand examples and their label details
These figures describe specific plain chopped-tomato listings; check the label of the pack you buy, particularly if it is a different size or a seasoned variant.
Mutti
Mutti describes Polpa as finely chopped tomatoes suited to longer cooking.
- ASDA Groceries lists Mutti Polpa 400g at 2.8g sugars per 100g, with tomatoes (99.8%) and salt as ingredients.
- The same listing declares 0.30g salt per 100g; account for that when seasoning the curry.
Napolina
The Napolina 400g listing at Tesco Groceries is for chopped tomatoes and juice with citric acid.
- Tesco Groceries declares 3.6g sugars per 100g for that listing and does not list sugar among its ingredients.
- Check the nutrition and ingredients on the exact multipack rather than assuming every Napolina pack has an identical formulation.
Tesco
Tesco Italian Chopped Tomatoes 400g is a plain tomato and concentrated tomato juice product with citric acid.
- The Tesco Groceries ingredient list does not include sugar.
- Tesco Groceries declares 4.0g sugars per 100g for this tin, compared with 2.8g per 100g for the specified Mutti Polpa listing at ASDA Groceries.
Sainsbury's
Sainsbury's Italian Chopped Tomatoes are listed as a four-pack of 400g tins.
- Sainsbury's Groceries lists tomatoes, concentrated tomato juice and citric acid, with 3.5g sugars per 100g.
- The per-100g figure is for the specified Italian chopped-tomato four-pack, not every Sainsbury's tomato product.
ASDA
ASDA Groceries has separate plain and herb-seasoned chopped-tomato listings.
- The plain Chopped Tomatoes listing declares 3.8g sugars per 100g and does not list sugar as an ingredient.
- The Chopped Tomatoes with Herbs listing declares 2.9g sugars per 100g but does list sugar. Check which variant you have selected.
M&S
M&S Food lists Chopped Italian Tomatoes with tomato juice and citric acid.
- The specified listing declares 3.8g sugars and 0.02g salt per 100g.
- Compare its sugars figure with other plain tins if reducing the declared amount is your main consideration.

Image unavailable
Napolina Chopped Tomatoes 4 × 400g
The four-tin format may suit a few planned curries while keeping each 400g tin unopened until needed. Check this pack's nutrition and ingredients rather than assuming they match another Napolina pack size.
Image unavailable
Napolina Chopped Tomatoes 24 × 400g
Consider this larger pack only if twenty-four 400g tins fit your cooking plans and storage space. Read its own ingredients and per-100g nutrition panel: a different pack quantity does not, by itself, establish an identical formulation.
Questions about sugars and curry tomatoes
Does a lower sugars figure mean no sugar was added?
No. “Of which sugars” gives the total sugars, including those naturally present in tomatoes; the ingredients list answers a different question. ASDA Groceries lists sugar as an ingredient in its Chopped Tomatoes with Herbs despite declaring 2.9g sugars per 100g.
Which of the compared plain tins declares the least sugars?
Mutti Polpa has the lowest declared figure among the five specified plain chopped-tomato listings, at 2.8g per 100g on ASDA Groceries. That is a comparison of those listings, not a claim about every tinned tomato sold in the UK.
Should I use plain or herb-seasoned tomatoes for curry?
Choose a plain tin if you want to decide which herbs, spices and other seasonings go into the sauce. If you prefer a seasoned tin, check its exact ingredients: ASDA Groceries lists sugar in its Chopped Tomatoes with Herbs but not in its plain Chopped Tomatoes.
Does no sugar in the ingredients mean zero sugars?
No. The Mutti Polpa listing at ASDA Groceries names tomatoes and salt as ingredients but declares 2.8g sugars per 100g. Use the ingredients list to check what was added and the nutrition panel to compare total sugars.
What should I do with tomatoes left in an opened tin?
Follow the storage instructions on the tin you opened. Joybuy's Napolina 400g listing says to transfer the contents to a non-metallic container, cover, refrigerate and use within two days; check the exact product rather than applying that period to every brand.
