For savoury bake-sale recipes, compare the salt declared per 100g on the exact tin before deciding how many to buy. ASDA Groceries lists 0.01g per 100g for both ASDA Chopped Tomatoes and Just Essentials by ASDA Chopped Tomatoes; Marks & Spencer lists 0.02g for its Chopped Italian Tomatoes. Texture and batch size still matter, and the salt in toppings and other ingredients needs separate consideration.
Who is this for?
School bake-sale organisers
If you are making pizza-style slices, savoury muffins or pasta bakes, you need enough tomato for the batch and ingredient information for the sale. Check the school’s arrangements before deciding how food will be packaged.
Parents comparing tomato bases
Checking the tin’s salt figure can help you compare the tomato component. Look at cheese, sauces, stock and other ingredients separately when planning the finished bake.
Bakers choosing a sauce texture
Visible tomato pieces may suit one recipe, while a finer pulp may spread more evenly in another. Decide which texture the bake needs, then check that product’s salt declaration.
What should you check?
Start with the nutrition panel and recipe texture, then work out the number of tins the batch will use.
| Priority | What to check | Your needs |
| Declared salt |
Compare salt per 100g on the exact variant. ASDA Groceries lists 0.01g for ASDA and Just Essentials by ASDA chopped tomatoes; Marks & Spencer lists 0.02g for its Chopped Italian Tomatoes. Check the ingredients list as well. |
I want to compare the tomato base on the same per-100g basis, rather than judge it by its packaging or description. |
| Whole recipe |
Check the ingredients you will add to the tomatoes, including cheese, sauces, stock, seasonings or cured meat. A tin’s salt figure describes the tomatoes, not the finished bake. |
The recipe includes other ingredients, so I need to consider those before describing the finished food. |
| Texture |
Decide whether pieces of tomato will work in the bake or whether a finer pulp is needed. Napolina describes its chopped tomatoes as chunky; Mutti’s product is finely chopped. Their stated salt values also differ. |
I need a tomato base that spreads or cooks as the recipe requires, without assuming a texture tells me its salt content. |
| Quantity |
Calculate the tomatoes needed from the recipe and check the number and size of tins in a pack. Read the exact tin’s instructions before planning to use opened leftovers. |
One or two tins may cover a small batch; for a larger batch, I want to buy the quantity I can use and store appropriately. |
| Sale arrangements |
Confirm the school’s food-sale process and whether items will be packaged before sale. Keep ingredient information for every component, not just the tomatoes. |
I need to organise ingredient and allergen information before deciding how to present the bakes for sale. |
What can catch you out?
-
Assuming Italian tomatoes contain less salt
For the products compared here, Napolina states 0.10g salt per 100g and the ASDA Groceries listing for Mutti Finely Chopped Tomatoes states 0.30g. Both ASDA chopped-tomato products state 0.01g per 100g. These figures describe the named products, not every tin from either brand.
Read the nutrition panel for the exact tin, then make a separate decision about texture.
-
Checking the tomatoes but not the toppings
Cheese, sauces, stock and cured meat can contribute salt to a savoury bake. Choosing a tomato tin by its per-100g figure does not establish the salt content of the finished recipe.
Review the full ingredient list for the bake before choosing quantities or describing it to buyers.
-
Buying more tins than the batch needs
A multipack may leave unopened tins after a small bake sale, while opened tomatoes need storage according to their own label.
Calculate the batch requirement first and check the pack count before ordering.
-
Settling packaging before ingredient information
How food is prepared and packaged affects which allergen-labelling guidance applies. The Food Standards Agency sets out requirements for food businesses producing food prepacked for direct sale in England, Wales and Northern Ireland; that description should not be assumed to cover every school fundraiser.
Ask the school how the sale will operate, retain the labels for every ingredient and clarify the applicable packaging arrangements before baking.
Relevant brand references
These figures refer to the named tomato products, not to every product made by each brand.
ASDA
ASDA Chopped Tomatoes 400g is an own-label option to compare when declared salt is the main consideration.
- ASDA Groceries lists 0.01g salt per 100g and ingredients including tomatoes, concentrated tomato juice and citric acid.
- Check the label on the tins being purchased in case product information has changed.
Just Essentials by ASDA
The named 400g chopped-tomato tin provides another own-label salt figure to compare.
- ASDA Groceries lists 0.01g salt per 100g, with tomatoes, tomato juice and citric acid in the ingredients.
- That figure should not be applied to other products in the range without checking their labels.
M&S
Chopped Italian Tomatoes are a further named option for comparing declared salt.
- Marks & Spencer lists 0.02g salt per 100g and ingredients including Italian chopped tomatoes, tomato juice and citric acid.
- Check local stock before relying on this product for the event.
Napolina
Napolina describes its chopped tomatoes as chunky, which may matter when tomato pieces are wanted in the bake.
- Napolina states 0.10g salt per 100g for its chopped tomatoes.
- That declared figure is above the named ASDA and M&S examples; check the exact pack when buying.
Mutti
Finely Chopped Tomatoes offer a finer pulp where the recipe calls for a more even tomato texture.
- The ASDA Groceries listing identifies tomatoes and salt in the ingredients and states 0.30g salt per 100g.
- If minimising the tomato component’s declared salt is the priority, compare that figure with the other named products before choosing by texture.

Common questions
Do ‘reduced salt’ and ‘no added salt’ mean the same thing?
No. Check the wording of each claim, the ingredients list and the declared salt per 100g separately. ASDA Groceries lists 0.01g per 100g for its ASDA and Just Essentials by ASDA chopped tomatoes, whose listed ingredients do not include added salt; its Mutti Finely Chopped Tomatoes listing includes salt in the ingredients and states 0.30g per 100g.
What if the savoury bakes are packaged before sale?
Confirm who is organising the sale and how the food will be packaged before preparing labels. Food Standards Agency guidance says food businesses producing food prepacked for direct sale in England, Wales and Northern Ireland must provide the food name and a full ingredients list with allergenic ingredients emphasised. Ask the school which arrangements apply to its event.
How should I plan to use tomatoes left in an opened tin?
Follow the storage directions on the exact tin rather than assuming every brand gives the same period. Plan the batch around the quantity needed, and check the label’s instructions for transferring and refrigerating any leftovers.
